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 the heat that is taken away by the smoke of the boiler. Its size is related to the amount of smoke, the smoke exhaust and the reference temperature and the

Get A QuoteWith shell boilers, economizers will generally only be fitted to boilers using natural gas as the main fuel and then only on larger units. It would be unlikely that a reasonable economic case could be made for boilers of less than 4000 kg/h F and A 100°C evaporative capacity. The economizer will incorporate a flue gas bypass with isolating

The heat emitted by the flue gas = (flue gas inlet enthalpy value x inlet temperature-outlet enthalpy value x outlet temperature) x flue gas volume The method of calculating boiler evaporation is as follows 1.

Get A Quotesens) in kJ/kWh is a function of the flue gas mass flow rate (m FG) in kg/kWh, flue gas temperature (T) in K, and specific heat capacity of the flue gas (C FG)) in kJ/kgK: (4) Thus, the higher the mass flow rate and the higher the temperature of the flue gas, the higher the heat lost up the stack.

Then, the gas volume required for the operating hours of a 1 ton natural gas boiler = 0.7 MW * 3600 s / 36.22 MJ / Nm3 / 92% = 75 m3 / h. Note: The actual power of the boiler is generally not equal to the rated power, so the consumption of gas is only a rough estimate.

Get A QuoteThis calculation translates the steam load (in pounds per hour) to boiler horsepower. Each boiler is given a boiler horsepower (BHP) rating based on the steam output capacity at 212°F and 0 psig. For this calculation, you will enter the steam load in pounds per hour, which will be divided by a constant of 34.5.
