Dry distillation, reversal combustion and normal combustion integrated biomass combustion method and device

Abstract

The invention discloses a dry distillation, reversal combustion and normal combustion integrated biomass combustion method and a distillation, reversal combustion and normal combustion integrated biomass combustion device. Three combustion modes are realized simultaneously by using a special feeding device and a special combustion device; the feeding device is independent of a furnace body; materials are fed by a feeding box on one side of the furnace body, the reversal combustion is performed at a fire grate near the side of the feeding box, biomass fuel entering the furnace from the feed port of the furnace body is positioned below the obliquely arranged fire grate and is normally combusted; and after the biomass fuel is combusted for certain time, the feed box is heated by the produced heat, so that the biomass fuel in the feed box is promoted to be subjected to dry distillation, and the produced combustible gas enters the fire grate through a passage between the feed box and the furnace body and is combusted. Through the combination of the three combustion modes, the insufficient utilization of the biomass fuel is reduced, and ash content is reduced. Meanwhile, the invention provides a combustion device for realizing dry distillation, reversal combustion and normal combustion; and the three combustion modes are realized by using the feed device on one side of the furnace body and the obliquely arranged fire grate.

Description

technical field [0001] The invention relates to biomass combustion, in particular to a biomass combustion method and device integrating dry distillation, reverse burning and normal burning. Background technique [0002] We know that in order to fully burn biomass fuel and reduce ash content and reduce pollution, biomass fuel must be subjected to various combustion methods, including dry distillation, reverse combustion, and normal combustion. However, the current stove structure cannot make it Biomass fuels all go through these three combustion methods, so the defects of the prior art are that the biomass fuels cannot be fully burned, producing too much ash and polluting the environment with too many pollutants. Therefore, it is necessary to design a biomass combustion device that can integrate dry distillation, reverse combustion and normal combustion. Based on this device, a specific biomass combustion method should also be given. Contents of the invention [0003] The ...
