Biomass fuel combustion furnace

Abstract

The invention discloses a biomass fuel combustion furnace. The biomass fuel combustion furnace comprises a smoke collecting hood (1), a heat exchange chamber (2), a combustion chamber (3), a furnace pipe chamber (4), a hopper (5) and a control system. The smoke collecting hood (1) is arranged at the upper end of the heat exchange chamber (2), and the lower end of the heat exchange chamber (2) is connected with the combustion chamber (3). The lower end of the combustion chamber (3) is connected with the furnace pipe chamber (4). A feeding port (17) is formed in one side of the combustion chamber (3) and connected with the hopper (5) through a spiral feeder (20). A motor of the spiral feeder (20) and the control system are electrically connected. A furnace pipe overcomes the defects that furnace pipe ventilation holes are prone to blockage, and starting of an ignition device is hindered through a large amount of ash; rapid ash cleaning is facilitated, the device overhauling time is shortened, and the combustion efficiency of the device can be better improved; and automatic control and various sensors are adopted in the whole system, real-time monitoring can be achieved, the labor cost is saved, and device running safety performance detection is improved.

Description

technical field [0001] The invention relates to the technical field of heating equipment, in particular to a biomass fuel combustion furnace. Background technique [0002] Biomass Molding Fuel (Biomass Moulding Fuel, referred to as "BMF") is made of agricultural and forestry wastes as raw materials, through crushing, mixing, extrusion, drying and other processes, and made into various shapes (such as block, granular, etc.), which can A new type of clean fuel for direct combustion. Biomass fuel has a large calorific value, about 3900-4800 kcal / kg, and does not contain other sundries that do not generate heat. Its carbon content is 75-85%, ash content is 3-6%, and water content is 1-6%. 3%, absolutely does not contain coal gangue, stones and other impurities that do not generate heat but consume heat. Biomass briquette fuel is widely used and economically sustainable, and it has been paid more and more attention by people. [0003] However, incomplete combustion often occur...

AI Technical Summary

Problems solved by technology

[0003] However, incomplete combustion often occurs during the combustion process, which will generate a large amount of dust particles to accumulate and block the bottom of the furnace. After a long time, the combustion efficiency of biomass will be seriously affected, and some energy will be wasted. In order to give full play to the advantages of biomass particle combustion, A new type of combustion furnace is needed
