Description

Technical Field

[0001] The utility model relates to the technical field of biomass fuels, in particular to a slag discharging device for a biomass combustion furnace. Background Art

[0002] The biomass combustion furnace uses biomass formed fuels, such as broken firewood, firewood, straw, corncobs, various fruit shells, and various biomass briquettes, etc. Through the air supply of a blower, the control of the furnace temperature and the air intake volume is realized, so that the fuel is fully gasified and burned in the furnace. This combustion furnace has multiple functions such as cooking, heating, and boiling water, and the waste generated by combustion is mainly ash slag.

[0003] The existing biomass combustion furnace adopts dry or wet treatment for the discharge of ash slag. Dry treatment requires special arrangements on the combustion furnace and the smoke pipe to ensure the system's sealing while removing ash. Subsequently, the ash slag is conveyed to the ash storage by a screw conveyor or a chain conveyor. Wet treatment is to wet-treat the ash slag at the bottom of the combustion furnace for easy centralized cleaning, and it can also be transported as agricultural organic fertilizer.

[0004] For the above two mainstream methods of cleaning ash slag, dry treatment requires special device arrangements to ensure sealing. Otherwise, ash slag leakage and floating will pollute the air and make it more difficult to clean. At the same time, the high temperature of the ash slag is likely to cause harm to the operator and the heat recovery efficiency is low. Although wet treatment is inexpensive and easy to collect, the ash slag cannot be placed in the combustion furnace for a long time, otherwise it is easy to corrode the combustion furnace. For this reason, we propose a slag discharging device for a biomass combustion furnace. Content of the Utility Model

[0005] The purpose of the utility model is to provide a slag discharging device for a biomass combustion furnace, which includes a first cooling component fixedly connected to the bottom end of the biomass combustion furnace.

[0013] 1. In the present utility model, the bottom of the combustion furnace is connected through a connecting pipe, and the ash slag enters the first cooling component. The ash slag is initially cooled by the cooling water circulating in the external condensing pipe.
