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.

INCREASING THE ENERGY EFFICIENCY OF BOILER

2019-11-18 · 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. Energy output (boiler thermal efficiency) is between 75 and 77 percent.

Boiler (power generation) - Wikipedia

2019-10-13 · A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam generator.
