Problems solved by technology

[0003] Existing staged combustion devices for the co-combustion of biomass liquid fuel and metal particles generally use the biomass liquid fuel to burn the metal particles when the two are fully combusted. After the two are in contact, the metal particles accumulate in the biomass liquid. In the fuel, there are blank spots of biomass liquid fuel in the contact part of the accumulated metal particles. During the combustion process, the biomass liquid fuel burns rapidly, which cannot effectively burn the metal particles sufficiently, reducing the combustion effect

Abstract

The invention belongs to the technical field of staged combustion, particularly relates to a staged combustion device for co-combustion of biomass liquid fuel and metal particles. The staged combustion device aims at solving the problem that when an existing biomass liquid fuel and metal particle co-combustion staged combustion device performs sufficient combustion of the biomass liquid fuel and the metal particles, the metal particles are generally combusted through the biomass liquid fuel, after the biomass liquid fuel and the metal particles make contact, the metal particles are accumulatedin the biomass liquid fuel, blank points of the biomass liquid fuel exist at the contact positions of the accumulated metal particles, in a combustion process, the biomass liquid fuel is rapidly combusted, the metal particles cannot be effectively and sufficiently combusted, the following solution is provided, and the staged combustion device comprises a combustion furnace. According to the staged combustion device, through arrangement of a net plate and an ejecting rod, when the metal particles are subjected to secondary combustion, the metal particles fall on the ejecting rod of the net plate, the ejecting rod is of a sawtooth structure, and therefore the metal particles are ejected up, the contact area of the metal particles is reduced, and the combustion area is maximized in the combustion process.

Description

technical field [0001] The invention relates to the technical field of staged combustion, in particular to a staged combustion device for co-combusting biomass liquid fuel and metal particles. Background technique [0002] Metal has a very high energy density, and a large amount of energy will be released during its combustion process. It has significant advantages such as high heat flux density, no carbon emissions, and recyclability; The material liquid fuel is placed in the same combustion furnace so that the two are co-combusted to achieve the effect of burning metal particles. Therefore, the combustion operation needs to be carried out through a staged combustion device in which the biomass liquid fuel and metal particles are co-combusted. [0003] Existing staged combustion devices for the co-combustion of biomass liquid fuel and metal particles generally use the biomass liquid fuel to burn the metal particles when the two are fully combusted. After the two are in cont...
