Abstract

The invention discloses a transformed coal-fired boiler to deal with the current hazy weather. The transformed coal-fired boiler comprises a boiler body, wherein at least one burner is arranged under the boiler body, each burner is connected with a burner combustion liquid inlet pipe, the tail end of each burner combustion liquid inlet pipe is connected with a liquid inlet pipe, an air blower duct is arranged under each burner, and each burner is provided with an electronic ignition device; an air control butterfly valve is arranged on each air blower duct, a butterfly valve air regulating handle is installed on each air control butterfly valve, and each air control butterfly valve is installed on the corresponding air blower duct through a butterfly valve flange; a liquid inlet electromagnetic valve is arranged on each burner combustion liquid inlet pipe, and each burner is also connected with an excess liquid drainage pipe. The coal-fired boiler is low in operation cost, an original coal-fired boiler can be reutilized, experimental detection proves that emission is totally qualified, labor force is reduced, and fully-automatic ignition and liquid feeding are achieved, so that the automation degree is increased.

Description

technical field [0001] The invention belongs to the field of boilers, in particular to a modified coal-fired boiler. Background technique [0002] At present, the smog weather in our country is getting worse and worse. The state has stepped up efforts in environmental governance and banned heavily polluting coal-fired boilers. Many units and enterprises in the traditional thermal field have suffered economic losses. If the original coal-fired boiler is transformed into a boiler burning alcohol-based liquid fuel, it can not only meet the requirements of the national emission standard, but also fully reflect the social and economic benefits. Therefore, there is an urgent need for a low-emission environment-friendly boiler with a high degree of automation and the ability to burn alcohol-based fuels. Contents of the invention [0003] The invention proposes a reformed coal-fired boiler, which solves the problem that common boilers in the prior art are likely to cause environm...
