Description

Technical Field

[0001] The utility model relates to the technical field of boilers, in particular to a coal-fired and gas-fired dual-purpose boiler. Background Art

[0002] At present, boilers are usually used as energy conversion equipment in urban heating systems. Boilers can be divided into coal-fired boilers and gas-fired boilers according to the fuel used. Since the gas produced by coal burning contains a large amount of air pollutants, especially particulate matter, these air pollutants will cause serious urban air pollution if they are directly discharged without treatment. Gas-fired boilers are widely used because they do not produce particulate matter. However, most boilers are still coal-fired boilers. Due to the different structures of coal-fired boilers and gas-fired boilers, fuels cannot be mixed.

[0003] In short, coal-fired boilers account for the vast majority of usage, but they can cause air pollution. Although gas-fired boilers are environmentally friendly, they rely on a stable gas supply. At present, the gas source problem has not been well solved, so there are certain disadvantages in using only coal-fired or gas-fired boilers. It is necessary to provide a coal-fired and gas-fired dual-purpose boiler that can reduce the environmental burden and not affect the normal use of the boiler to the greatest extent.
