Industrial coal-fired boiler

Abstract

The invention relates to the technical field of boilers, in particular to an industrial coal-fired boiler. The industrial coal-fired boiler comprises a bottom frame, a boiler body, a crawling ladder and a sealing mechanism, a plurality of supporting rods are arranged at the top of the bottom frame, the boiler body is arranged at the top ends of the supporting rods, the boiler body is of a hollow structure, a pot cavity is formed in the boiler body, a furnace body is arranged in the pot cavity, and the crawling ladder is installed on one side of the boiler body. Convenience is brought to use ofthe industrial coal-fired boiler, a platform is installed at the top end of the boiler body, and people can stand on the upper edge to carry out operation on the top end of the industrial coal-firedboiler through the platform; and hot gas and smoke dust generated by combustion in a furnace cavity are discharged out of the industrial coal-fired boiler through a steel pipe, and when the hot gas and the smoke dust pass through the steel pipe, heat in the hot gas and the smoke dust can be transferred to the pot cavity through the steel pipe to heat water in the pot cavity, so that the heat of waste gas is reused, energy consumption is reduced, and the economic benefits are increased.

Description

technical field [0001] The invention relates to the technical field of boilers, in particular to an industrial coal-fired boiler. Background technique [0002] Industrial coal-fired boilers refer to coal burned as fuel. After the heat of coal is transformed, steam or hot water is generated. Industrial coal-fired boilers are compactly arranged, occupy a small area, have short installation periods, low installation costs, and low user investment. The recovery benefit is fast. [0003] However, the existing climbing ladders for industrial coal-fired boilers are not installed stably enough, and they may fall down or cause burns when they come into contact with the furnace body of the industrial coal-fired boiler, which reduces the safety of the industrial coal-fired boiler. The oxygen in the furnace cavity of industrial coal-fired boilers is not sufficient enough to make the coal burn more thoroughly, thereby reducing the utilization rate of coal, increasing the input of raw ma...

Problems solved by technology

[0003] However, the existing climbing ladders for industrial coal-fired boilers are not installed stably enough, and they may fall down or cause burns when they come into contact with the furnace body of the industrial coal-fired boiler, which reduces the safety of the industrial coal-fired boiler. The oxygen in the furnace cavity of industrial coal-fired boilers is not sufficient enough to make the coal burn more thoroughly, thereby reducing the utilization rate of coal, increasing the input of raw materials, and reducing economic benefits. At the same time, coal is burned in the furnace cavity When it is not sufficient, it is easy to produce harmful gases. The hot gas and smoke generated by the combustion in the furnace cavity are directly discharged into the air, and the heat of the exhaust gas is not reused, which increases energy consumption. Large particle pollutants in the smoke will also pollute the air. cause serious pollution
