What is the use of condensing waste heat recovery boiler technology?
Traditional boiler, the exhaust temperature is generally 160 ~ 250 ℃, flue gas in the water is still in a state of overheating, can not condense into liquid water and release latent heat of vaporization.
The condensing waste heat recovery boiler, which reduces the exhaust gas temperature to 50 ~ 70 ℃, fully recovered the smoke in the sensible heat and water vapor latent heat, enhance the thermal efficiency; condensate can also be recycled.
So the traditional boiler thermal efficiency can only reach 87% to 91%.
It is well known that the thermal efficiency of the boiler is calculated from the low calorific value of the fuel and does not take into account the heat loss of the latent heat of vaporization in the high calorific value of the fuel.
