Biomass energy gasification furnace apparatus

Abstract

The invention discloses a biomass energy gasification furnace appliance, which is invented to solve the problem such as difficult elimination of burnt dust in the prior art. The biomass energy gasification furnace appliance comprises an upper furnace body and a lower furnace body that are axially installed, and a furnace grill is installed at the middle bottom of the lower furnace body; a feeding hole is installed at the top of the upper furnace body; a fuel gas outlet is opened on the lateral wall at the lower part of the upper furnace body; a gas bushing is axially installed inside the upper furnace body, and a gap is installed between the gas bushing and the top and inner wall of the upper furnace body so as to form a gas passage; the lower end of the gas bushing is positioned below the underside extension line of the fuel gas outlet; and a cooling water jacket is axially installed at the external surface of the upper furnace body corresponding to the gas bushing. The structure above is used so that combustible gas produced from the furnace bodies enters the gas passage in reversed manner from the upper part, thereby prolonging the buffer time when fuel gas is detained inside the furnace body by using indirect cooling of external water jacket, enhancing dedusting effect, and solving the problem of serious plugging of burnt dust better.

Description

technical field [0001] The invention relates to a biomass energy gasifier appliance. Background technique [0002] With the advancement of science and technology, biomass gasifiers are favored by many businesses and users for their advantages of high efficiency, energy saving, and wide application range. Biomass energy gasification furnace is to pyrolyze and dry biomass raw materials such as straw, branches and leaves, weeds, wood chips, grain husks and cores under the condition of isolated air to obtain combustible gas. After purification, the combustible gas can reach the standard of urban artificial gas , with a calorific value above 15 MJ / m3, it is an ideal gas source for civil cooking gas. Although our country has made gratifying achievements in the promotion and application of biomass energy at this stage, the structure of the existing biomass energy gasifier is relatively simple, there is coke dust that is difficult to handle, and the kitchen hygiene is affected duri...
