CH4+2O2=CO2+2H2O）In high temperature discharge, it is discharged in the form of acid superheated vapour in air, this is not only
Also can aggravate the greenhouse effects of the earth to environment.
For above-mentioned, condensing waste-heat recovery device generally carries out hot friendship using multigroup distributive pipe in parallel with high-temperature flue gas
Change, the latent heat that the sensible heat in high-temperature flue gas and water recovery are discharged is utilized, for preheating backwater, reach energy-conservation it
Purpose.But, due to being limited by waste-heat recovery device volume, each distributive pipe is often difficult to flow, and flow difference causes
It is heated uneven, heat exchanger effectiveness can not give full play to, the latent heat that the sensible heat and water recovery in high-temperature flue gas is discharged is not
Can make full use of.
