17/3/2015 · 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.

Read MoreFlue Gas Waste Heat Boiler Thermal Efficiency Calculation Kefid 17:02:11 Boiler heat efficiency refers to the heat input into the boiler, most of which are absorbed by the boiler heating surface to produce water vapor, which is the heat that is effectively utilized, and the remaining heat is called heat …

Read MoreEvaporator The heat load of the evaporator part of the boiler can be calculated as: φ EVAP = m& SH (h′′ − hECO 2) + m& BD (h′ − hECO 2) (2) where m& SH is the mass flow of steam before superheater [kg/s], h ′′ the specific enthalpy of saturated steam at steam drum pressure [kJ/kg], hECO 2 the specific enthalpy after economizer m& BD the mass flow of blowdown water from steam drum, and h ′ the specific enthalpy of saturated water at steam drum pressure [kg/s]. 8 fSuperheater Normally superheating takes place in three or four stages in a big boiler.

Read MoreThe thermal efficiency of a boiler specifies the effectiveness of the heat exchanger of the boiler which actually transfers the heat energy from fireside to water side. Thermal efficiency is badly affected by scale formation/soot formation on the boiler tubes.

Read Morecalculation of heat input of water to boiler ZOZEN Boiler Co., Ltd. as a professional industrial boiler manufacturer, we are founded in 1988. In the past 30 years, we design and produce more than 400 different types of boilers, such as gas-fired and oil-fired boilers, biomass-fired boiler, thermal oil heaters, chain grate boilers, CFB boilers and etc.
