Boiler – Fundamentals and Best Practices
Steam Production When heat is added to water, its temperature rises at a rate of 0.56 C (1 F) for each heat input of 2.095 kJ/kg (1 Btu/lb) If we take water at 0 C (32 F) and we add 419 kJ/kg (180 Btu/lb) then we will increase the temperature of the water by 100 CGet Price
Boilers | Why return condensate to the boiler? The best reasons …
2010/4/21 · If condensate isn't returned to the boiler, the steam system must make up the loss with cold, untreated, raw water that has to be prepared for boiler operation. This preparation has a cost. The make-up water also contains substantially less BTU content that must be raised in the deaerator or atmospheric feed water heater.Get Price

How to Correctly Size a Steam Boiler | Info Centre | News
All steam boiler manufacturers use this rating because they must take the standard assumption that water evaporates at 100ºC and that feed water is 100ºC. The actual evaporation temperature of water at higher pressures is higher than 100ºC and the amount of condensate return will affect the feed water temperature.Get Price
How do you calculate steam output on a boiler?
2020/4/24 · How do you calculate steam output on a boiler? Use btu/hr (British thermal units/hour) heat input rate to calculate boiler steam flow. It takes 970.28 btu/hr to produce 1 pound of steam at the above conditions. If 50 million btu/hr are being applied to the boiler, divide by the 970.28-btu/lb to yield 51,531-lb/hr steam flow.Get Price
