Description

Technical Field

[0001] The utility model belongs to the technical field of combustion furnaces, and specifically relates to a combustion furnace for efficient utilization of biomass natural gas heat energy. Background Art

[0002] A high-efficiency biomass combustion furnace is a device specifically designed to burn biomass fuels (such as wood, agricultural waste, energy crops, etc.) to generate heat energy. This type of combustion furnace usually adopts advanced combustion technologies and designs to improve combustion efficiency, reduce pollutant emissions, and maximize the utilization of biomass resources.

[0003] Chinese Patent with application number CN202121579890.8 discloses a high-efficiency biomass combustion furnace, which relates to the field of combustion furnaces. It includes a bottom plate, and support legs are fixedly installed on the lower surface of the bottom plate. In this high-efficiency biomass combustion furnace, by setting a second motor, a rotating shaft, and a dispersing rod, the rotating shaft can be driven to rotate, and the biomass can be dispersed by the dispersing rod, facilitating the smooth entry of the biomass into the furnace body. By setting a first motor, a crushing shaft, and crushing teeth, the crushing shaft can be driven to rotate, and the biomass can be broken by the crushing teeth, enabling the biomass to burn better and more fully.

[0004] In the above-mentioned prior art, the biomass material is broken by setting a dispersing rod and crushing teeth. However, in actual use, the broken material directly falls onto the heating grid plate and accumulates, which easily leads to a reduction in combustion efficiency and incomplete combustion of some biomass materials. Moreover, the gas generated by combustion is directly discharged, resulting in energy waste.

[0005] In view of this, the present utility model is specifically proposed. Content of the Utility Model

[0016] Preferably, a blower is installed on one side of the furnace body, an installation groove is opened on the front side of the furnace body, and a cleaning door is rotatably fitted on the inner wall of the installation groove.

[0017] After adopting the above technical solutions, the present utility model has the following beneficial effects compared with the prior art. Of course, any product implementing the present utility model does not necessarily need to achieve all the advantages described below at the same time:

[0018] By setting the material distribution roller shaft and the touch rod, the crushed biomass material enters the blanking shell. When driving the material distribution roller shaft, the rotation of the material distribution roller shaft makes the biomass material in the blanking shell evenly discharged. When the material distribution roller shaft rotates, under the extrusion of the eccentric wheel, the touch rod moves up and down, knocking on the heating grid plate, causing the heating grid plate to vibrate, and dispersing the material accumulated on the heating grid plate, improving the combustion effect of the biomass material. Through the heat energy recovery mechanism, the heat energy in the flue gas is recovered and utilized, improving the energy utilization rate.
