An automatic ash discharge device for a burner has a furnace base, a duct set, and a discharge set. The furnace base has a combustion chamber, a mounting opening, a discharge mouth, two guiding faces, and multiple inlet holes. The combustion chamber is formed in the furnace base. The guiding faces are formed aslant in the furnace base. The inlet holes are formed through the guiding faces. The duct set is connected to the furnace base and has two casings and a blower. The casings are mounted on the furnace base respectively corresponding to the guiding faces and communicate with the combustion chamber. The blower communicates with the casings. The discharge set is connected to the furnace base and has a receiving tank connected to the furnace base and communicating with the combustion chamber, and a discharge shaft rotatably mounted in the receiving tank.

An apparatus for waste recycling that is suitable for residence building level in both volume and rate of supply of waste with a waste disposal and treatment container having the following parts: waste eliminator comprising a thermally and acoustically insulating casing with odour insulating raw waste receiving space; all-purpose shredder and crusher; crushed and/or shredded waste conveyor; liquid waste purifier; gasification plasma reactor; gas conveyor and purifier; slag collector; re-hydration means for re-hydrating solid waste in the gasification plasma reactor; and safety means. Each one of these parts is organized in fluid communication with its neighbor parts.

A method processes slag occurring in a combustion chamber. An incineration grate is formed at least in its end region that is facing the slag-removing device as a separating grate, which has openings, via which the chamber is connected to a fine-slag discharge chamber, and at least one fine fraction of the slag is ejected through the openings into the discharge chamber and discharged in a substantially dry state, and the remaining coarse fraction is fed to the slag-removing device and discharged. In this case, the average particle size of the at least one fine fraction is smaller than the average particle size of the coarse fraction. The separating grate has at least in certain regions air feeds that are distributed over its entire width and via which air is fed in a controlled manner to the slag, and the air feeds are isolated from the openings and formed separately.

A combustion-type exhaust gas treatment apparatus has a combustion treatment chamber for treating exhaust gas by combusting and decomposing the exhaust gas, a main burner for forming a flame in the combustion treatment chamber by supplying a mixture gas produced by premixing a fuel gas and an oxidizing gas, and a scraper for scraping off solid matters adhering to an inner wall of the combustion treatment chamber. The mixture gas is adjusted within combustion range and supplied to the main burner during treatment for treating the exhaust gas by combusting and decomposing the exhaust gas when the scraper is not in operation, and the mixture gas is adjusted outside combustion range and supplied to the main burner during treatment for treating the exhaust gas by combusting and decomposing the exhaust gas when the scraper is in scraping operation.

Systems and methods are disclosed for pyrolysis of waste feed material. Some systems include a main retort and a secondary retort. Syngas is produced by pyrolysis in the main retort, and is then mixed with combustion air and ignited, in some cases to produce energy. Carbon char travels to the secondary retort and is exhausted from the system through an airlock.

A gasifier system for reducing the particle size of non-gas byproducts of the gasification process. The gasifier system generally includes a grinder that permits uninterrupted syngas flow during gasification of biomass that contains high amounts of silica and/or salts. The described system and method incorporates a grinder that breaks apart the resultant non-gas byproducts into finer particles that may be flushed out of a gasifier using the syngas stream. The particles may then be easily separated from the gas stream in a separator and collected in a char or waste bin for removal/disposal.
