The following are the ultimate analysis for coal: Calculate the stoichiometric air requirement. Carbon-38%, Ash-35%, Hydrogen-5%, Sulphur-2%. For the same data, calculate the theoretical CO 2. If the actual measured CO 2 is 8%, find out the excess air levels? 29. A packaged boiler is operating at 5% O 2. Find out the excess air level? 30.
Calculating Power Plant Coal Consumption--ZBG
Feb 12, 2021 · Boiler Capacity = 5200 X 18 = 93600 kg/hr =93600 / 1000 = 93.6 TPH. 5-Calculate the Theoretical air & Excess air required to burn 10 MT of coal having carbon (C) 48%, Hydrogen (H2) 3.8%, Oxygen (O2) 8.2% & Sulphur (S) 0.6% in it. For complete combustion operator is …
What are boiler efficiency and boiler evaporation ratio
150 MW requires coal consumption: 10765/(10500 kJ/kg to 25000 kJ/kg)x150 This is the theoretical value of the estimation, and the actual power plant coal consumption is related to the quality of coal and the efficiency of boilers.

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.
=steam flow (enthalpy of steam -enthalpy of feed water) / coal flow * gcv. For example if there is a 80mw boiler with 540 dig centigrade of main steam temperature, feed water temperature of 300 dig centigrade, coal flow 56 ton, gcv 4000 kcal/kg then the boiler efficiency will be =307(826.28-242.58)/56*4000=80%.
Boiler Horsepower. 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.
