摘要:
The present invention addresses the problem of providing a carbonaceous fuel gasification method capable of gasifying a carbonaceous fuel at a high yield, a iron mill operation method for utilizing a carbonaceous fuel through gasification thereof at a high yield, and a gasified gas production method capable of producing a gas through gasification from a carbonaceous fuel at a high yield. The problem is solved by supplying a carbonaceous fuel, and a gasification agent containing H 2 , CO 2 , and H 2 O, to a fluidized bed gasification furnace which employs aluminum oxide as a fluidization medium.
摘要:
A direct carbonaceous material to power generation system integrates one or more solid oxide fuel cells (SOFC) into a fluidized bed gasifier. The fuel cell anode is in direct contact with bed material so that the H2 and CO generated in the bed are oxidized to H2O and CO2 to create a push-pull or source-sink reaction environment. The SOFC is exothermic and supplies heat within a reaction chamber of the gasifier where the fluidized bed conducts an endothermic reaction. The products from the anode are the reactants for the reformer and vice versa. A lower bed in the reaction chamber may comprise engineered multi-function material which may incorporate one or more catalysts and reactant adsorbent sites to facilitate excellent heat and mass transfer and fluidization dynamics in fluidized beds. The catalyst is capable of cracking tars and reforming hydrocarbons.
摘要:
A gasification apparatus for solid fuel, especially an apparatus for producing syngas by pressurized gasification of coal powder, including a gasification chamber (II) and a syngas cooling chamber (III). The inner wall of the gasification chamber is a water-cooling wall (4). The inner side of the water-cooled wall is evenly coated with a layer of fire-resistant material (16). There is an annular cavity between the water-cooling wall of the gasification chamber and the furnace body. A syngas cooling device, a vertical pipe (22), a gas distribution device (24), a defoaming device, and a dewatering and deashing device (21) are provided in the syngas cooling chamber. Said syngas cooling device is connected with a cone-shaped disk at the bottom of the gasification chamber. The vertical pipe (22) is connected with the syngas cooling device. The lower portion of the vertical pipe (22) is connected with the trumpet-shaped gas distribution device (24) via a smooth transition. A baffle device is arranged above the gas distribution device (24), above which a defoaming device is arranged. The apparatus has a simple structure and is easy to operate. A high temperature gasification method for dry powder of carbonaceous material comprises spraying the combustible material and oxygen into the furnace and followed by ignition.
