Pumps for boilers
Thread Content
I took a look at the boiler technology posts in this section and saw only one post about pumps used in heat transfer oil boilers. I’d like to learn more about the use of pumps in other types of boilers; thank you!
We don’t use many pumps for boilers; the main ones include the boiler feed pump, deaeration pump, dust removal pump, and chemical dosing pump.
Pumps used in boilers mainly include feed water pumps for steam boilers and steam pumps； Circulating hot water pumps for hot water boilers, etc. The specific pump model is selected based on parameters such as the boiler’s output and rated operating pressure.
Pumps used in boilers mainly include: the feedwater equipment for steam boilers consists of steam piston pumps, electric centrifugal pumps, and recirculation pumps for forced circulation, whose function is to supply water to the boiler continuously. General steam piston pumps are used in small industrial boilers or as backup pumps in the event of a power outage ； Electric centrifugal pumps are the most widely used feed water pumps in boilers. Power station boilers employ this type of pump. Due to the high pressures in boilers, feed water pumps are always multi-stage centrifugal pumps, which can be divided into three categories: segmented type, horizontally split type, and cylindrical type ； The working fluid in the circulation pump is high-temperature and high-pressure boiler feed water, and shaft-sealless designs are generally used. Shaft-sealless pumps come in two types: those equipped with shielded motors and those equipped with wet motors, with the latter being more widely used. Hot water boilers use recirculation pumps, and the specific model to be selected should be determined based on the boiler’s parameters as well as the pump’s flow rate and head.
The pumps we use include boiler feed water pumps, condensate water pumps, fire pumps, ammonia pumps, and phosphate pumps
