Calculation method of excess air ratio for blast furnace

Abstract: As the influence of nitrogen content in fuel gas is not considered in the conventional calculation method (1) of the excess air ratio in the flue gas, the calculation method is not appropriate in the calculation of thermal efficiency for the blast furnace gas fired boiler. In this paper, the calculation formula (18) of the excess air ratio in the flue gas for the blast furnace gas

Boiler modulation – is more better? - HPAC Magazine

Boilers are rated on their thermal efficiency, which is simply the ratio of the chemical energy added to the boiler over the energy added to the boiler water. As more heat is transferred from the hot gas into the boiler water, the thermal efficiencies increase and the exiting (flue) hot gas temperatures decrease.
