Abstract

The invention discloses a biomass fuel hot air stove, which aims to provide a biomass fuel hot air stove with simple structure, low cost, convenient repair, full fuel combustion, high heat conversion efficiency and small occupied area. The biomass fuel hot air stove comprises a stove body, a feeding system, a grate (8), a flue (9) and a curved reflex arch (16), wherein the stove body is divided into three parts including an air chamber (5), a combustion chamber (15) and a heat conversion device by the feeding system together with the curved reflex arch (16). After the biomass fuel fed by the feeding system is combusted on the grate (8), the volatile component of the biomass fuel is combusted over the combustion chamber (15) for the second time. The generated heat enters the heat conversion device together with the high-temperature smoke for heat energy conversion, then cold smoke is discharged from the flue (9), and the obtained hot air can be used for heating. The biomass fuel hot air stove can be widely used in the field of common hot air heating.

Description

technical field [0001] The invention relates to a biomass fuel hot blast stove. Background technique [0002] In industrial production, many processes use layer-fired hot blast stoves for heating. Due to the high calorific value of coal, less volatile matter, and the relatively simple structure of coal furnaces, people usually still use coal as the main energy fuel. With the increasing shortage of coal resources, countries all over the world are vigorously developing and innovating the technology of biomass combustion and utilization to solve various problems caused by the energy crisis in the future. However, due to the high water content, low volatile point, high volatile matter and low energy density in biomass fuel, it is difficult to form stable combustion conditions using the existing layer-fired coal-fired hot blast stove technology. At present, the biomass-fired hot blast stove products that can be practically used all use fluidized bed combustion technology or vap...
