Multi-fuel combustor

Abstract

The invention discloses a multi-fuel combustor, which comprises a biomass gas mechanism, a natural gas mechanism, a light fuel mechanism, and a fuel combustion device connected with the biomass gas mechanism, the natural gas mechanism and the light fuel mechanism. The fuel combustion device comprises a fan set and a combustion mechanism connected with the fan set; a combustor, a combustion furnace head connected with the combustor, and a fire watching pipe located at the outer side of the combustor are arranged on the combustion mechanism; the light fuel mechanism penetrates through the fire watching pipe so as to enter the combustor; the combustion furnace head is provided with a plurality of air rotary vanes and connecting pipes, an air cone and a fuel gas branch pipe; the plurality of air rotary vanes are located in the combustion furnace head; the air cone is matched or connected with the connecting pipes; the fuel gas branch pipe is connected with a fuel gas hole in the air cone. The multi-fuel combustor provided by the invention is simple and scientific in design, and can adopt multiple fuels, so that a user can select the favorable fuel to switch for combustion, the production cost is reduced, the profit margin is improved, and the multi-fuel combustor is wide in application range so as to be worth to be popularized.

Description

technical field [0001] The invention belongs to the technical field of heating systems, and specifically describes multi-fuel burners for heating systems such as horizontal fuel oil and gas boilers. Background technique [0002] Biomass gas (producer gas) is to use crop straw, forest waste, edible fungus residue, livestock manure and all combustible substances as raw materials to convert combustible energy. Biomass gas is inevitable for agricultural development and utilization of biological resources. However, the current combustion quality of biomass gas burners is low, and the heat energy released is not as good as that of traditional fossil fuels. In addition, it is troublesome to prepare combustion materials and is prone to failure. [0003] In heating systems such as horizontal oil-fired and gas-fired boilers, the burners currently used can only burn a single fuel and cannot be adapted to various fuels. The scope of application of the burner is small, and it cannot be...

Problems solved by technology

However, at present, the combustion quality of biomass gas burners is low, and the heat energy released is not as good as that of traditional fossil fuels. In addition, it is troublesome to prepare combustion materials, and it is prone to failure, etc.

[0003] In heating systems such as horizontal fuel oil and gas boilers, the burners currently used can only burn a single fuel and cannot be adapted to various fuels.

The scope of application of the burner is small, and it cannot be well promoted. Users cannot choose fuels that are beneficial to them according to the market fuel price, thereby reducing production costs.
