Problems solved by technology

[0005] Commonly used gas-fired boilers are designed according to the high calorific value of natural gas as fuel. When used to burn biomass gas, the output will be much lower at first, and the thermal efficiency of the boiler is low, because the calorific value of biomass gas is only 1 / 8~ of natural gas. 1 / 6, if the air distribution is not good, it will be difficult to burn out, and the stability will be poor when the heat load is low

Abstract

The invention discloses a steam boiler combusting biomass gas. The steam boiler combusting the biomass gas comprises a boiler body and a combustion chamber which are arranged at the top and bottom separately, wherein the boiler body comprises a smoke discharge channel communicating with the combustion chamber, and boiler barrels used for holding water, and a smoke discharge port is formed in the smoke discharge channel; the boiler barrels are located at the upper side and the lower side of the smoke discharge channel, a plurality of water-cooling wall pipes communicating with the boiler barrels are arranged in the smoke discharge channel, and a steam outlet is formed in the boiler barrel at the upper side; a biomass gas combustor is installed at a gas inlet end of the combustion chamber; and a secondary air connector is formed in a part close to the junction of the combustion chamber and the smoke discharge channel, in the combustion chamber. The steam boiler combusting the biomass gasis high in heat efficiency, clean and environment-friendly, and extremely low in pollutant discharge.

Description

technical field [0001] The invention relates to the field of steam boilers, in particular to a steam boiler burning biomass gas. Background technique [0002] The steam boiler is a kind of energy conversion equipment. The energy input to the steam boiler has the form of chemical energy in the fuel, electric energy, heat energy of high-temperature flue gas, etc., and after the conversion of the steam boiler, it outputs a steam carrier with a certain heat energy. [0003] In the context of increasingly stringent national environmental protection policies, environmental protection emission standards have gradually increased. Traditional industrial boilers that use coal and fuel oil as fuel have been difficult to meet the country's continuously upgrading environmental protection emission requirements. On the one hand, the energy cost of steam boilers has doubled, which is difficult for enterprises to bear. On the other hand, some enterprises do not have a nearby supply of pipeli...
