Smokeless, coal saving type heat transfer oil stove with large mechanical fire grate

Abstract

The present invention relates to a smokeless coal-saving large-size mechanical fire grate heat-conducting oil-burning boiler. It is characterized by that said furnace body has heating zone and hot gas supply zone, the interior of furnace body of heating zone is equipped with heat-absorbing tube bank, the bottom portion of heating zone is equipped with a hot gas inlet, and the top portion of said heating zone is equipped with a draught fan; the hot gas supply zone possesses a coal-burning device, said coal-burning device has a combustion furnace cavity, meachinical fire grate, coal-adding device and high-temperature gas outlet. Said invention also provides the concrete structure of said furnace cavity. Said invention is simple in structure and can completely solve the problem of discharging black smoke by burning coal.

Description

technical field [0001] The invention relates to an improved smokeless coal-saving large-scale mechanical grate heat-conducting oil furnace. Background technique [0002] Heat conduction oil furnace, also known as organic heat carrier boiler, is a new type of industrial boiler that has only been developed in recent years. Due to its small size, flexible installation and layout, and low operating costs, heat-conducting oil series boiler equipment is very popular among users and has a broad market prospect. [0003] The form of heat transfer and circulation of the heat conduction oil furnace is to use the heat conduction oil as the medium, and the circulation oil pump is used to force the heat conduction oil to circulate in the liquid phase, and the heat energy is transported to the heat-consuming equipment through the pipeline, and the heat conduction oil after heat transfer and cooling passes through the return pipeline Get back to the heating furnace to reheat to form a clo...

AI Technical Summary

Problems solved by technology

The existing heat-conducting oil furnace coal-fired devices basically have the problem of insufficient coal-fired combustion, and the emission of black smoke is serious. For some large-scale mechanical grate (including chain grate, reciprocating grate, etc.) coal-fired facilities, The situation is slightly better, and the exhaust gas is also gray or black gray. On the one hand, it causes environmental pollution, and on the other hand, there is a serious waste of energy. Large-scale coal-fired devices with a combustion power above 2.8MW have a coal consumption of 6- 20 tons / 24 hours, or even more, the coal consumption is quite large, the pollution of coal-fired flue gas is quite serious, and the waste of coal resources is quite alarming, which seriously restricts the smooth implementation of an environmentally friendly and energy-saving society
