Dec 20, 2021 · The radiant heating surface of the gas boiler is a fully corrugated furnace, and the convection heating surface uses a threaded smoke tube. A flue gas condensation recovery device is arranged at the tail of the boiler. The size of the furnace is consistent with the flame, which greatly reduces the heat loss, and the thermal efficiency can reach more than 95%.

in boilers, but the most common types of fuel include coal, oil, and natural gas. During the combustion process, oxygen reacts with carbon, hydrogen, and other elements in the fuel to produce a flame and hot combustion gases. As these gases are drawn through the boiler, they cool as heat is transferred to water.
