Steam Calculators: Boiler Calculator

Mar 17, 2015· 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.

Making sense of boiler ratings - HPAC Magazine

Aug 16, 2017· 1) IBR Gross Output: This is the amount of heat energy actually transferred to the water during steady state operation. The assumption of this particular rating is that any heat lost through the boiler jacket is wasted and does not contribute to the building heating load. This rating assumes the boiler is in an unheated space.

Boiler Capacity - Engineering ToolBox

Boiler load - the capacity of a steam boiler - is often rated as boiler horse powers, lbs of steam delivered per hour, or BTU. Lbs Steam delivered per Hour. Large boiler capacities are often given in lbs of steam evaporated per hour under specified steam conditions. BTU - British Thermal Units.

Normally superheating takes place in three or four stages in a big boiler. This calculation example is based on three stage superheating. The heat load of the first superheater stage is SHI = mSH (hSHI −h′′),2. φ & (3) where hSHI,2 is the specific enthalpy of steam after the first superheater stage.

Boiler load control: Header pressure or steam flow

If the load increases then the master pressure output will increase and thereby increase the set point of the fuel flow and air flow controllers causing the boiler to increase steam output to meet the new load demand with the header pressure eventually returning to set point and steam flow increasing to the required value to support the load condition.

Boiler - Wikipedia

Energy. The source of heat for a boiler is combustion of any of several fuels, such as wood, coal, oil, or natural gas. Electric steam boilers use resistance- or immersion-type heating elements. Nuclear fission is also used as a heat source for generating steam, either directly (BWR) or, in most cases,
