How does the condensing gas boiler work?
In the conventional boiler, the exhaust gas temperature is generally 160 to 250C or higher, so that the water (such as natural gas: CH4 + 2O2? CO2 + 2H2O) generated in the combustion of the fuel is in a state of superheat in the flue gas.
Condensation boiler is the key to condensation technology, is a new energy-saving, environmentally friendly technology; her principle is not complicated, a simple summary is through the flue gas condensate recovery of flue gas heat.
More advanced condensing gas boilers use smoke-free combustion technology, so that nitrogen oxides (NOx can lead to acid rain and greenhouse effect) emissions reduced to 35mg / kwh outside.
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 flue gas to the harmful substances in the flue gas collected into the condensate, the acidic substances and other pollutants are reduced to the air
Conventional boiler thermal efficiency is generally only 85% to 91%.
