Steam Calculators: Boiler Calculator

Steam, Boiler, and Blowdown Pressure are the same. Combustion Efficiency is the % of fuel energy that is directly added to the feedwater and not otherwise lost or used. Blowdown Rate is the % of incoming feedwater mass flow rate that leaves the boiler as a saturated liquid at boiler pressure.

Boiler and Condenser Pressures - Rankine Cycle

2019-6-28 · Boiler and Condenser Pressures. As in the Carnot, Otto and Brayton cycle, the thermal efficiency tends to increase as the average temperature at which energy is added by heat transfer increases and/or the average temperature at which energy is rejected decreases. This is the common feature of all thermodynamic cycles. Condenser Pressure

Boiler Feedwater Treatment (Part I): Why Water …

2015-8-20 · Boiler feedwater. Boiler 'feedwater' is the water supplied to the boiler. Often, steam is condensed and returned to the boiler as part of the feedwater. The water needed to supplement the returned condensate is termed 'make-up water'. Make-up water is usually filtered and treated before use.

2019-6-25 · Steam heating boilers are used to generate steam at low pressures, such as 15 psig. Generally, these two basic heating systems are treated as closed systems, because makeup requirements are usually very low. High-temperature hot water boilers operate at pressures of up to 500 psig, although the usual range is 35-350 psig.
