Combustion device convenient to use

Abstract

The invention discloses a combustion device convenient to use and aims to provide a combustion device which is simple to operate and convenient to use. The combustion device comprises a furnace shell, a furnace container, an igniter, a smoke discharging pipe, a conveyor and an air blower, wherein the furnace container is arranged inside the furnace shell; a furnace bar device is arranged at the bottom of the furnace container; a gap is formed between the furnace container and the furnace shell; the igniter penetrates through the furnace shell and the furnace container and is close to the upper end surface of the furnace bar device; the smoke discharging pipe is arranged at the upper part of the side wall of the furnace container and penetrates through the furnace shell; the conveyor is arranged at the upper part of the side wall of the furnace container and is opposite to the smoke discharging pipe; the air blower is arranged on the furnace shell and is communicated with the gap; the gap of the furnace container is communicated with the lower space of the furnace bar device; an air inlet pipe is arranged at the upper part of a pipeline in the gap of the conveyor; the air inlet end of the air inlet pipe is located in the gap; a channel for taking out coked blocks is formed in the lower part of the furnace container; the channel extends to the furnace shell; and a cover for opening and closing the channel is arranged on the furnace shell. The combustion device does not need to halt in the process of taking out the coked blocks; the continuity of baking heat supply can be ensured.

Description

technical field [0001] The invention relates to the technical field of combustion equipment, in particular to an easy-to-use combustion device. Background technique [0002] In the existing combustion device for biomass fuel, the material is transported into the furnace through the corresponding conveying mechanism. When some biomass fuel with high tar content is used for combustion, coking is easily formed in the furnace of the combustion device. It is combing through the ash discharge grate device, and the dissolution of the coking mass cannot be achieved. Any time the burning time increases, the coking mass will become larger, resulting in a serious reduction in the air intake capacity of the grate, which in turn causes the biomass fuel to burn slowly and heat supply. The amount is reduced and cannot meet the heating requirements.

[0002] In the existing combustion device for biomass fuel, the material is transported into the furnace through the corresponding conveying mechanism. When some biomass fuel with high tar content is used for combustion, coking is easily formed in the furnace of the combustion device. It is combing through the ash discharge grate device, and the dissolution of the coking mass cannot be achieved. Any time the burning time increases, the coking mass will become larger, resulting in a serious reduction in the air intake capacity of the grate, which in turn causes the biomass fuel to burn slowly and heat supply. The amount is reduced and cannot meet the heating requirements

At the same time, since the furnace is closed, the staff can only take out the coking blocks when the heat supply is significantly reduced during use. The pipe is clamped by auxiliary tools. The smoke outlet pipe is usually connected with the drying device. Every time coking occurs, the combustion device needs to be shut down to cool down and disassembled, which takes a long time and seriously affects the continuity of heating.

Furthermore, a gap is set between the furnace shell and the furnace to realize the heat preservation of the combustion device. Although this heat preservation method can achieve the heat preservation effect, when the air in the gap reaches a certain temperature, there is still heat radiation loss, and the energy saving effect is still high. needs improvement

At the same time, the temperature of the smoke outlet pipe of the existing combustion device is high during use, and the heat radiation loss is relatively large, resulting in waste of heat energy
