Due to the advantages of high thermal efficiency and green environmental protection, gas-fired boilers currently occupy a high number of boiler companies, so are gas-fired boilers polluting? What substances do gas boiler rooms emit?

　　Are gas boilers polluted?

　　Gas-fired boilers have relatively few pollutants. Except for a small amount of sulfur or other components, carbon dioxide and water are produced when fully burned, which is much better than coal-fired and other environmental protection aspects. The specific types of pollutants are as follows:

　　1. Carbon monoxide, gas will produce carbon monoxide when it cannot be fully burned.

　　2. Sulfur dioxide, after entering the atmosphere, sulfur dioxide SO2 is oxidized to sulfuric acid (SO4) to form acid rain in the cloud, which is harmful to the environment.
