Abstract

The invention provides an atmospheric clean coal-fired hot water boiler, which comprises a combustion chamber, a fire grate and a return smoke pipe. The front end of the furnace is connected to the hopper, and the rear end is connected to the slag outlet. There are 4 blowers under the grate. The return smoke pipe includes the first return smoke pipe and the second return smoke pipe. One end of the first return smoke pipe is connected to the combustion chamber The top is connected, the other end is connected to the smoke chamber, one end of the second return smoke pipe is connected to the smoke chamber, and the other end is connected to the smoke outlet. The boiler of the invention uses clean briquette coal as the main fuel, has the advantages of sufficient combustion, high heat energy utilization rate, and small smoke and dust, has wide application fields, can replace bulk coal boilers, and is beneficial to environmental protection.

Description

technical field [0001] The invention belongs to the field of heating equipment and relates to an atmospheric clean type coal hot water boiler. Background technique [0002] As the country gradually increases the control of air pollution, the use of coal-fired boilers that use loose coal as fuel is restricted, while oil-fired boilers, gas-fired boilers, and coal-fired boilers are used more and more. The fuel costs of oil-fired and gas-fired boilers Expensive and difficult to promote. In recent years, briquette boilers have been vigorously promoted because of their advantages such as low operating costs, low pollution emissions, and energy saving. The market prospect is good. [0003] Briquette is a clean fuel, the main components include anthracite, coke powder, binder, rice husk or sawdust, combustion improver and desulfurizer, etc. Briquette boilers using this as fuel may not be equipped with dust removal equipment. It also has the characteristics of small initial investme...
