The difference between a condensing boiler and an ordinary gas boiler is that the smaller the heat load of the condensing boiler, the higher the thermal efficiency. The heat load of the entire heating season is about 30-50%, so the condensing boiler can maintain a higher thermal efficiency.
Boiler House: It is introduced that the lower the return water temperature of the condensing boiler, the higher the thermal efficiency, but when the return water temperature is lower than 50 ℃, the ordinary gas boiler will produce a large amount of condensate, so the condensing boiler has high requirements on the boiler material.
The full premixed combustion method can control the ratio of air and gas within the range to ensure that the excess air coefficient of the mixed gas is between 1.2-1.3, which can not only ensure the full combustion of fuel, but also reduce the generation of nitrogen oxides and reduce boiler heat loss .
The condensing boiler adopts a blast-type fully premixed burner. The surface of the combustion head is made of metal fiber braid. Only a layer of light blue flame is formed on the cylinder wall of the combustion head, and due to the high temperature of the cylinder wall, a High-temperature radiation source. Compared with stainless steel atmospheric burners, metal fiber burners have both radiation heat exchange and convection heat exchange, and the heat exchange effect is better.
