Furnace-oven integral biomass fuel gasifying direct combustion furnace

Abstract

A furnace-oven integral biomass fuel gasifying direct combustion furnace relates to a fire furnace comprising a base, an ash casket, a funnel, a lower furnace body, a movable grate, an upper furnace body, a water outlet, a fume outlet, a sealed water box, a large cover plate, a small cover plate, a sealed water tank, a plugboard, and a blower. A furnace inner barrel is coated with fire resisting cement heat preservation layer and provided with an inner water sealing ring, an upper cover is provided with an oven bench and configured with a secondary air fitting pipe 16, the upper furnace body 9 consists of an anaerobic gasifying chamber and a gasifying combustion chamber, the combustion material is thereon provided with a penetration proofing plate 8, the lower part inside the furnace is provided with the grate, an ash clearing chamber is arranged below the grate, a closed ash clearing door is arranged, the ash cleaning chamber is externally connected with a primary air pipe 23 and a blower 22; the lower furnace body 4 and the upper furnace body 9 are installed fixedly and integrally and are connected with the base, the upper cover plate 13 is matched with a furnace ring cover and the upper cover plate is thereon provided with a gasifying furnace, thus achieving full gasifying combustion of combustion materials in the furnace, having simple structure, low cost, no pollutant discharge and being favorable for application in civil or public heating and other heat sources.

Description

technical field [0001] The invention relates to a fire-burning furnace, in particular to a biomass fuel gasification direct-fired furnace in which a furnace and a stove are integrated. Background technique [0002] There are many kinds of civil or public burning stoves, and the fuels used are also different, generally coal stoves, oil stoves or wood stoves. There are also biomass fuels such as crop rice husks, weeds, and straws as fuels, but generally they must be pressed into blocks and then directly sent to the furnace for burning. There are also gas furnaces that gasify biomass fuel and then burn it, but most of them have complex structures and high costs, and it is difficult to popularize and apply them for general civilian use. Contents of the invention [0003] The purpose of the present invention is to provide a biomass fuel gasification direct combustion furnace. The combustion material in the furnace is equipped with an anti-penetration plate, and is equipped wit...
