Boiler Capacity - Engineering ToolBox

Example - Boiler Horsepower to lbs of Steam Conversion. 200 hp x 34.5 = 6900 lbs of steam per hour. Lbs of steam can be converted to hp by dividing lbs steam per hour by 34.5. Example - Lbs of Steam to Boiler Horsepower Conversion. 5000 lbs of steam / 34.5 = 145 hp boiler. Converting Boiler Horse Power (BHP) to kBtu/hr

Steam Boiler | Working principle and Types of Boiler

Mar 04, 2020 · Boiler or more specifically steam boiler is an essential part of thermal power plant. Steam boiler or simply a boiler is basically a closed vessel into which water is heated until the water is converted into steam at required pressure. This is most basic definition of boiler. The basic working principle of boiler is very very simple and easy to

Steam Mass Flow Rate - an overview | ScienceDirect Topics

The pilot plant was built indoors in the same format as a standard vertical boiler. The steam mass flow rate was 13.8 t/h at full load. The steam produced by the boiler was throttled down to 50 bar and condensed in a small air condenser formed by two cells of a typical lubrication-oil fin fan cooler.

Calculating Boiler Efficiency - Leaders in Steam Engineering

In order to calculate boiler efficiency by this method, we divide the total energy output of a boiler by total energy input given to the boiler, multiplied by hundred. Calculation of direct efficiency- E= [Q (H-h)/q*GCV]*100. Q= Quantity of steam generated (kg/hr) H= Enthalpy of steam (Kcal/kg) h= Enthalpy of water (kcal/kg)
