The application of condensing technology can effectively improve the operating efficiency of oil-fir

Condensing technology is a new energy-saving and environmentally friendly technology, and it is the key to improving the efficiency of condensing oil and gas boilers. The principle of condensing technology is not complicated. A simple summary is to recover the heat energy in the flue gas by condensing the flue gas. Zhengzhou Fangkuai Boiler Factory will explain in detail the application of condensing technology to effectively improve the operating efficiency of oil-fired and gas-fired boilers.



The exhaust gas temperature of traditional boilers is generally around 160~250℃ or even higher, so that the water produced during fuel combustion (such as natural gas: CH4+2O2→CO2+2H2O) is in the superheated state of water vapor in the flue gas, and the smoke Gas is lost from the chimney. The thermal efficiency of traditional boilers can only reach 85%~91%. The condensing gas boiler reduces the exhaust gas temperature to 50~70℃, fully recovers the sensible heat in the flue gas and the condensation latent heat of water vapor, and the thermal efficiency can reach up to 109%.

The core of the condensation technology is to reduce the heat loss of fuel combustion and efficiently absorb the heat generated by the fuel. At the same time, due to the condensation of the flue gas, the harmful substances in the flue gas are collected into the condensed water, reducing acidic substances and other pollutants into the air. emission. More advanced condensing gas boilers use smokeless combustion technology, which reduces the emission of nitrogen oxides (NOx can cause acid rain and greenhouse effect) to beyond 35mg/kwh.
