Difference between condensing wall-hung boiler and ordinary wall-hung boiler

There are three main differences between condensing wall-hung boilers and ordinary wall-hung boilers, as follows:

1, combustion technology is different.

The condensing wall-hung boiler recovers the residual heat in the flue gas, and its combustion mode is fully premixed proportion adjustment, and the exhaust temperature can be reduced to about 40℃. In conventional wall-hung boilers, the mixing ratio of gas and air can not always achieve complete combustion, so the heat loss taken away by flue gas is large, the pollutant emission index is high, and the thermal efficiency under partial load is low compared with full load. The exhaust temperature is higher than 120℃.

2, the service life is different.

Because of the advanced technology, the service life of condensation wall-hung boiler is generally much longer than that of traditional wall-hung boiler, which is about 25 years in theory. Due to the design of heat exchanger, combustion chamber and other key parts, as well as water quality problems, the service life of ordinary wall-hung boilers can theoretically reach 15 years.

3. Energy saving efficiency is different.

The thermal efficiency of condensing wall-hung boiler is greater than 9 1%. The new condensation technology can automatically control the flue gas temperature, and recover the heat in the flue gas during combustion, so that the flue gas temperature can be reduced to 50~70℃, which is very energy-saving. The thermal efficiency of ordinary wall-hung boilers can only reach 85%~9 1%, because the flue gas temperature of ordinary wall-hung boilers is high, and the water generated during fuel combustion is in a vapor state in the flue gas, which leads to the loss from the flue gas and reduces the thermal efficiency.
