Boiler feed pumps are also referred to as feed pumps (see ) and designed as multistage. (Also see.) They serve to feed a steam generator such as a boiler or a nuclear reactor with a quantity of feed water corresponding to the quantity of steam emitted. Today, all boiler feed pumps are. The design of boiler feed pumps regarding, and is largely governed by the developments which have taken place in power station technology. The trend in fossil-fuelled power stations is towards larger and larger power station units ( 1000 MW in 2011). This has led to boiler feed pumps with a of 30 - 50 MW. Until 1950, the average in the outlet cross-section of the pump (discharge pressure of the feed pump) was in the 200 bar region.
By 1955 the average discharge pressure had risen to 400 bar. The were in the region of 350 tonnes/h in 1950, compared to 3200 tonnes/h (in some exceptions up to 4000 tonnes/h) today. Boiler feed pumps operate at fluid of 160 to 210 ºC. In exceptional cases the temperature of the fluid handled may be higher still. Feed pumps for 1600 MW nuclear power stations are constructed for mass flow rates of up to 4000 tonnes/h and feed pump discharge pressures of 70 to 100 bar.
Until 1950 approximately, boiler feed pumps were made of unalloyed steels; since then they have been made of steels with a chrome content of 13 - 14%. This change of materials was made necessary by the introduction of new chemical feed water compositions. The development of highstrength, corrosion and erosion resistant martensitic chrome steels with good anti-seizure properties as well as the continuous development of all pump components (bearings, shaft seal, pump hydraulic system, etc.) paved the way for present-day boiler feed pumps with rotational speeds of 4500 to 6000 rpm. The mass flow rates of centrifugal pumps rose rapidly in conjunction with the rise of unit outputs in power stations.
Today's full load feed pumps for conventional 800 to 1100 MW power station units are constructed with four to six stages with stage pressures of up to 80 bar. Feed pumps for 1600 MW nuclear power stations are of the single-stage type. Drive In the case of conventional power stations above 500 MW full load feed pumps are increasingly driven by steam turbines. In most cases condensing turbines running at 5000 to 6000 rpm are used.
Usually drive part load feed pumps, both in fossil-fuelled and in nuclear power stations. Speed control of electrically driven feed pumps is effected by either (e. Variable speed turbo couplings) or by electrical systems by means of (up to a drive rating of approximately 18 MW in 2011).
Four options of installing boiler feed pump drives are commonly used at present. 1 Boiler feed pump Fig. 1 Boiler feed pump: Model with VP-EM-RG-HP layout The low-speed booster pump is usually driven by the free shaft end of the turbine via a step-down gear or directly by the free end of the electric motor.
2 Boiler feed pump Fig. 2 Boiler feed pump: Arrangement layouts of feed pump sets The single or double suction booster pump serves to generate the necessary NPSHR of the system for the high-speed boiler feed pump connected downstream. 3 Boiler feed pump Fig. 3 Boiler feed pump: Double-suction boiler feed booster pump Design For conventional power stations boiler feed pumps are designed as:. Multistage, see Fig. 4 Boiler feed pump., see Fig.
5 Boiler feed pump Fig. 4 Boiler feed pump: Barrel pull-out model with tapping stage Fig. 5 Boiler feed pump: Ring-section model with tapping stage These two types only differ in the construction of their pressure-retaining enclosure, which influences the manufacturing costs and ease of installation.
There are no differences with regard to operating reliability and robustness also in abnormal operating conditions. The dimensions of the rotating parts and flow passages can be designed identically. Two aspects of deciding between a ring-section and a barrel pull-out pump are described below:. The smaller the mass flow rate and the higher the pressure, the higher the material and manufacturing costs of barrel pull-out pumps. This does not apply to the same extent to ring-section pumps. Barrel pull-out pumps have some advantages over ring-section pumps when it comes to repairing a pump installed in the system.
If a rotor has to be replaced, the barrel (see ) can remain installed in the piping. This is significant with regard to the of a power station unit, if no full pump back-up is available or if pump replacement is very time-consuming. In the case of nuclear power stations, single-stage feed pumps with double-entry (see ) and double volute casing are usually adopted. 6 Boiler feed pump Fig. 6 Boiler feed pump: Double-suction reactor feed pump made of cast iron Cast pressure-retaining casing parts are increasingly replaced by forged parts. As an example, such a feed pump could be designed with a of about 4200 m3/h and a head of about 700 m at a rotational speed of 5300 rpm. 5 Boiler feed pump Heads of reactor feed pumps are in the region of 800 m for boiling water reactors and 600 m for pressurised water reactors.
The flow rates are about twice as high as those of a comparable boiler feed pump in a fossil-fuelled power station. Casing For boiler feed pumps two factors have to be considered regarding the wall thickness of the casing: the pressure loads and the different temperature conditions it needs to withstand. These two criteria are satisfied by adopting a high-strength ferritic casing material which enables the wall thickness to be kept thin enough to avoid any overloads as a result of temperature fluctuations, yet of adequate thickness to guarantee the requisite safety against internal pressure. Barrel casing. The casings of barrel pull-out pumps and barrel casing pumps are usually made of unalloyed or low-alloyed ductile forged steel. Deposit welding is used on all surfaces in contact with the feed water to coat them with corrosion and erosion resistant. In order to weld the pump into the, an adapter must be provided if the materials of the nozzles to be connected are from different material groups.
The discharge-side (discharge pressure containing) barrel cover is fastened by means of large non-torqued studs. Sealing is provided by a profile joint which is pressurised purely by the prevailing pressure (of up to several 100 bar) without any external forces acting on it. 7 Boiler feed pump Fig. 7 Boiler feed pump: Profile rings Ring-section pumps. The casings of ring-section pumps are preferably made of forged chrome or carbon steel plated with austenitic (iron solid solution) material. The between the individual stage casings (see ) seals off by metal-to-metal contact, the individual casings being clamped together axially by tie bolts between the suction and discharge casings (see ). Thermal shocks causing various thermal expansions mainly lead to additional loads on the tie bolts and sealing surfaces of the stage casings.
A common feature of barrel pull-out pumps and ring-section pumps is that the greater the wall thickness, the greater the thermal stress caused by thermal shocks, which in turn reduces the service life of the pump. The provision of injection water at a pressure situated between the suction and discharge pressure of the pump is a frequent requirement.
This is taken care of by tapping water from one of the pump stages of both barrel pull-out pumps and ring-section pumps. Tapping a stage of a boiler feed pump. In the case of ring-section pumps, a partial flow at an intermediate pressure can easily be tapped through a tapping nozzle in one of the stage casings. 5.
In the case of barrel pull-out pumps, the inside of the barrel is divided into three pressure zones so that a partial flow at the required intermediate pressure can be led off directly to the outside. 4 Barrel pull-out pump The sealing function is taken care of by a profile joint between the discharge and the tapping pressure, and by a metal-to-metal joint between the tapping and the inlet pressure. 7 Boiler feed pump Especially the profile joint allows a great degree of relative motion of the sealing surface, as required for any temperature shocks. Rotor design The of boiler feed pumps has a very small static deflection as the bearings are spaced as closely as possible, the shaft diameter is relatively large and the are usually shrunk onto the shaft (for high performance). The pump shaft is generally insensitive to and runs smoothly (see ) without any radial contact during normal operation. The hub diameter at the back of the impeller is increased and the impeller inlet geometry is designed with a minimum diameter, so as to reduce the remaining axial forces (see ) which have to be absorbed by the. The rotors of single-stage reactor feed pumps are even stiffer than those of boiler feed pumps, and their static deflection is smaller than that of multistage boiler feed pumps.
Axial thrust balancing Some arrangements of boiler feed pumps for conventional power stations cause at the impellers. 10 to 12 The magnitude of this axial thrust depends on the position of the on the characteristic curve, the rotational speed and the amount of wear on the internal clearances (see ). Additional disturbing forces can arise in the event of abnormal operating conditions, e.g. On larger boiler feed pumps the axial forces at the pump rotor are balanced by means of a hydraulic through which the fluid handled flows. The balancing device is often combined with an oil-lubricated thrust bearing (see ). As this balancing device absorbs more than 90% of the axial thrust, a relatively small thrust bearing can be used.
The balancing device may comprise a balance disc with balance disc seat, or a balance drum or double drum with the corresponding throttle bushes. Axial thrusts arising in reactor feed pumps with double-entry impeller (see ) are balanced hydraulically; residual thrusts are absorbed by an oil-lubricated thrust bearing. 6 Boiler feed pump Balancing of radial forces on the pump rotor Radial forces arise from the weight of the rotor, mechanical unbalance or hydraulic. The radial forces are balanced by two oil-lubricated radial bearings as well as by throttling clearances through which the fluid handled flows in axial direction. Such throttling clearances are located at the impeller neck on the impeller inlet side, or in the case of multistage boiler feed pumps for conventional power stations on the discharge side of the impeller (interstage bush) and at the balance drum. If the rotor is in an off-centre position, a re-centring reaction force will be generated in these clearances, which largely depends on the pressure difference and the clearance geometry (LOMAKIN effect).
The LOMAKIN effect is severely reduced when, due to abnormal operating conditions, the feed water in the clearance is not in a purely liquid phase (see ). The hydrostatic action of the clearances contributes more to reducing shaft deflection than the mechanical stiffness does. Ford cougar 2017. The system is designed in such a way that operating speed always remains well away from the of the rotor, allowing hydraulic exciting forces (particularly in low flow operation) to be absorbed in addition. An additional or a double volute can reduce radial thrust.
6 Shaft seal Common shaft seals for boiler feed pumps are mechanical seals, floating ring seals and labyrinth seals. Gland packings are less common these days. Warming up and keeping warm Transient or low flow operating conditions cause additional loads on boiler feed pumps. This leads to additional stresses and strains as well as to deformation of components with various consequences on their functionality.
Nowadays, almost all boiler feed pumps must be able to handle both cold starts (high-temperature shock loads) and semi-warm starts without any damage. In these start-up procedures hot feed water abruptly flows into the cold pump, which results in the inner components heating up much faster than the pressure boundary. Depending on the frequency of starts and the gradient curves of and (load cycles) this can shorten the service life of the pump. On machines with particularly thick walls the heat will propagate more slowly in the thick-walled components, thus increasing internal stresses. Contact between parts of the and the cannot, generally, be ruled out as narrow clearances are used as.
This applies to the impeller neck on the impeller inlet side, the discharge-side clearance between, and interstage bush as well as the balancing device with several throttling clearances (depending on the design). Critical operating conditions such as the formation of vapour bubbles, for example, cannot be completely avoided in the inlet line.
Brief contact between the stator and the rotor leads to high unbalance forces in the narrow clearances. For this reason the material pairs have to be resistant not only to corrosion and erosion but also especially to wear (incorporating good anti-seizure properties). Profiled chrome steels and a special clearance geometry have proven successful. In operating conditions with a very low or zero flow, e.g. In the turning gear mode of a turbine-driven boiler feed pump, temperature layers establish in the fluid handled, which may cause deformation of the rotors and, after a slight delay, also of the non-rotating components. Once the clearance gaps are closed the rotor will be subjected to a significantly higher friction moment, leading to overload of the turning gear and to standstill of the pump.
In this case, the temperature will no longer be equalised at the rotor, which will further aggravate the rotor deformation. This can result in several hours of downtime for the pump. Usually the only remedy is to let the machine cool down to reduce or eliminate the critical temperature layers and the deformation. Several actions can be taken to optimise the thermal behaviour of the pump: Avoid large differences in temperature in and on the pump. Thermally separate the cold areas (shaft seal area) from the area through which the hot fluid passes (hydraulic system and balancing device) by means of an insulation chamber system; provide a thermal seal to prevent convection flows and special thermosleeves. Insulate the outside of the pump. Warm up or keep warm the pump by means of forced flow through the machine, usually via throttled pressure supply.
Temporarily or permanently interrupt the cooling water supply in the area of the mechanical seal (secondary circuit). Limit the operating parameters for critical operating conditions (ΔT) (top/bottom of the barrel casing) and/or ΔT between casing and feed water.
Reduce the effects of large temperature differences. Rotate the pump in stand-by mode using turning gear. Employ synchronised turning gear (minimise or prevent actual standstill time). Drain water from critical thermal areas. Select good thermal characteristics when choosing. Fit a non-contacting seal (floating ring seal). The above measures are frequently used for as their outer dimensions, wall thickness, drive (turbine with turning gear) and operating modes are considered more critical than those of.
If possible, these measures are always automated to safeguard the of the. Minimum flow valve A minimum flow valve ensures a and thus prevents damage which could occur in as a result of either an impermissible increase in temperature leading to vaporisation of the pump content or low flow cavitation.
