Learn MoreNov 03, 2006 · What is the boiler horsepower of a boiler generating 21,500 lbs of steam per hour at 155 psi? The factor of evaporation is 1.08. BHP = (LB/HR*fe)/34.5 BHP = (LB/HR*fe)/34.5 BHP = 21500 * 1.08 / 34.5 BHP = 673 Where, BHP boiler horsepower Lb/Hr pounds per hour Fe factor of evaporation (can be assumed to be equal to 1)

Learn MoreThis is not an evaporation rate, and is subject to the same from and at factor. To establish the actual evaporation by mass, it is first necessary to know the temperature of the feedwater and the pressure of the steam produced, in order to establish how much energy is added to each kg of water.

Learn MoreFor small boilers, the general conversion is 1t / h = 0.7MW, the unit's power generation efficiency is generally 30% - 40%, that is, the evaporation (t / h) x 0.7x boiler power generation efficiency = power generation (MW). Therefore, it can be roughly estimated that the production of 1 MW of electricity will consume 3-4 tons of steam.

Learn MoreJun 23, 2017 · Equivalent Evaporation might be more simply defined as the quantity of water at 100°C that a boiler can convert into dry/saturated steam at 100°C from each kJ of energy that is applied to it. This defines it in terms of kg (of water/steam) per kJ of energy.

Learn MoreMar 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.
