Biomass furnace with liftable furnace grate

Abstract

The invention provides a biomass furnace with a liftable furnace grate, which comprises an outer hearth of the furnace, an inner hearth of the furnace, the furnace grate and a lifting mechanism, wherein the lifting mechanism is formed by mutually hinging four movable bars; a hinged part of a first movable bar and a second movable bar is connected with the furnace grate; a hinged part of a third movable bar and a fourth movable bar is connected with a furnace base; the distance from the furnace grate to a pot navel is changed through regulating the lifting mechanism, so as to enable that a pot bottom is used within the best temperature range of flame; and a flame blocking ring is positioned between an upper cover plate and a pot ring, and the cross section of the flame blocking ring is in the shape of an inverted isosceles trapezoid. According to the adoption of the flame blocking ring, high temperature flue gas and the flame circulate in the furnace and directly go at the pot bottom, so that carbon in fuels and combustible gas and solid particles in the flue gas can be fully combusted, the heated area of the pot bottom is increased, the residence time of the flame and the high temperature flue gas in the furnace is prolonged, the heat efficiency is improved, and the best heating effect is achieved. The biomass furnace is simple and convenient to regulate, is suitable for combusting various fuels and is an ideal product for building new socialist countryside and synthetically utilizing straw.

Description

technical field [0001] The invention relates to a stove, in particular to a biomass stove with a liftable grate, which is particularly suitable for a high-efficiency and energy-saving biomass stove for burning various fuels. Background technique [0002] Traditional rural stoves are mostly hand-built masonry structures with rough construction techniques. Due to insufficient combustion of coal or biomass, a large amount of smoke is released, and the indoor air pollution caused has become a major threat to human health. As countries around the world pay more and more attention to energy efficiency and air pollution, as well as the urbanization of rural areas in China and the improvement of farmers' living standards, traditional cooking and heating stoves and their inefficient combustion methods can no longer meet the needs. Household high-efficiency and low-emission biomass stoves can not only reduce coal consumption, reduce pollutant emissions, and improve indoor air quality,...
