  • Boiler feed pump | KSB

    Boiler feed pumps are also referred to as feed pumps (see Reactor pump) and designed as multistage radial flow pumps. (Also see Multistage pump.) 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 centrifugal pumps. The design of boiler feed pumps regarding

  • HVAC Hot Water Heating Systems | Old House Web

    Most hot water and steam heating systems have steel boilers with a service life of about 20 years. Cast iron boilers, which are less common, have a service life of about 30 years. Old cast iron boilers converted from coal fired units may last much longer but are usually quite inefficient. Inspect all boilers for signs of corrosion and leakage.

  • INCREASING THE ENERGY EFFICIENCY OF BOILER AND HEATER …

    Typical Energy Balance of a Boiler/Heater (before improvements) Energy in fuel enters the boiler (energy input 100 percent). From the boiler, 4 percent of heat loss is through radiation and convection, 18 percent is in flue gasses and 3 percent is in blowdown. Energy in heating medium (e.g. steam) exits the boiler.
