What factors will affect the thermal efficiency of a gas boiler?

The thermal efficiency of a gas-fired boiler affects the benefits that the boiler creates for the company per unit time; on the other hand, it affects the operating cost. The factors affecting the thermal efficiency of the boiler are as follows: (1)Boiler flue gas emissions carry away some of the heat. (2)The thermal efficiency of the boiler is affected by incomplete combustion of the fuel. (3)...

Why is the thermal efficiency of a gas steam boiler greater than 100%?

First of all, we must first know what is the high calorific value and low calorific value of the gas steam boiler fuel? The fuel calorific value is divided into high calorific value and low calorific value. High calorific value: All the heat released when the fuel is completely burned, including the latent heat of vaporization from the condensation of water vapor in the flue gas into water. Low ...
