The boiler adopts the idea of furnace design to reduce the furnace volume heat release rate, and with the professional burner, the NOx emission is as low as less than 30mg/Nm³. 99% of the natural gas is methane (CH4), which contains a large amount of hydrogen (H). The flue gas after combustion contains a large amount of water vapor. Through theoretical calculation, the share of water vapor in the flue gas is about 18%, if the water vapor is condensed into water to recover the latent heat of vaporization in it, the heat recovery is about 5%, and the boiler efficiency can be improved to more than 100%.
Boiler heat loss refers to the difference between the total heat released by the complete combustion of fuel in the boiler and the heat used by the boiler. It includes the heat taken away by the flue gas discharged from the boiler, the heat lost in the surrounding air by the furnace stack, the heat not released due to the unburned or incomplete combustion of the fuel, and the physical heat taken away by the ash. These losses are expressed as a percentage of the total heat released by the complete combustion of the fuel.
