Flue Gas Waste Heat Boiler Thermal Efficiency Calculation
Troubleshooting a Circulator Pump | DoItYourself.com
The losses caused by the sensible heat of flue gases can be calculated as: m& i φ L 3 = m& fuel ⋅ ∑ ⋅ hi (11) i m& fuel where m& fuel is the fuel mass flow [kg/s], m& i the mass flow of a flue gas component, and hi the specific enthalpy of a flue gas component (e.g. CO2) [kJ/kg].
Dec 16, 2020 · Heat Load on Furnace. You can calculate heat load on furnace from the heating requirement of process air. Q = Air flow rate*Heat Capacity*(620 110) Q = 6000*0.25*(620 110) = 765,000 kcal/h. Considering 5% heat loss from furnace actual heat requirement will be Q = 765,000*1.05 = 803,250 kcal/h.
L1 = percentage of heat loss owing to dry flue gas. C p = exact heat of flue gas, kCal/kg. T a = ambient temperature, o C. T f = temperature of flue gas, o C. GCV fuel = fuel gross calorific value. m = mass of fuel dry flue gas, kg/kg = fuel combustion products: SO 2 + CO 2 + nitrogen air provided definite mass + fuel nitrogen + flue gas of O 2
The heat efficiency of a flue gas waste heat boiler is the percentage of the effective heat in the heat injected into the fuel. The anti-balance test method is usually used to measure boiler thermal efficiency. The calculation formula for the thermal efficiency of the anti balance method: η= 100- (q2+q3+q4+q5+q6) 1. q2-flue gas heat loss The exhaust heat loss is the heat loss caused by a part of
