摘要:
A biomass thermochemical gasification apparatus is provided that can manufacture high-quality fuel gas out of solid biomass in an industrial manner. This fuel gas can be used as fuel for a gas engine and a gas turbine for example and also can be used as synthesis gas for methanol synthesis.A high-temperature combustion gas generation apparatus (101) for biomass operates entirely by biomass and the heat source thereof does not depend on fossil fuel. A coarsely-ground powder biomass (205) subjected to gasification and gasification agent (303) are introduced to a primary gasification reaction room (202) and generate gasification reaction by, as reaction heat, radiation heat from a wall face of the primary gasification reaction room (202) heated by combustion gas (109a) generated in the high-temperature combustion gas generation apparatus (101) and are dissolved. Consequently, the biomass (205) is converted to clean and high-quality generated gas.

A burner includes a plurality of air nozzles open toward a furnace and which are disposed unsymmetrically with respect to the central axis of the burner and so combined that the velocity of combustion air to issue from one or more of the nozzles is higher than the mean air velocity through the total air nozzle opening area and the velocity of combustion air from the rest of the nozzles is lower than the mean velocity. The opening area of the lower-velocity air nozzle or nozzles accounts for from 30 to 60% of the total opening area. A fuel nozzle or nozzles are located within or adjacent the lower-velocity air nozzle or nozzles. The amount of air to issue from the lower-velocity air nozzle or nozzles is not more than 70% of the theoretical air for the fuel to jet out of the burner.

Provided is a method for producing a production gas and an apparatus using the same with which a load may be increased in biomass treatment and the quality of the production gas may be improved. According to the present invention, a raw material fluid (F2) containing a biomass (M1) is supplied from an upstream end (22a) toward a downstream end (22b) in a raw material passage (22) separated from the outside by a reaction tube wall (21), and the raw fluid (F2) of the raw material passage (22) is heated from the outer side of the raw material passage (22) through the reaction tube wall (21) by a first heating means (F1). The raw material passage (22) comprises a first gasification region (23) where a first gasification reaction occurs in which at least part of the biomass is gasified by heating conducted by the first heating means (F1), and a second gasification area (25) disposed closer to the downstream end (22b) than to the first gasification region (23). Additional heating of the raw material fluid (F2) is conducted by a second heating means (30) at the second gasification region (25).

摘要:
A method for producing synthetic gas with which a virtually soot-free synthetic gas having a good composition can be efficiently obtained by a simple device using a liquid biofuel as the starting material, and it is thereby possible to produce a high-quality liquid fuel such as methanol, gasoline or kerosene. Steam and a liquid biofuel produced by pyrolysis of a biomass are fed to the gasification space inside a reactor tube that is not loaded with a catalyst inside the reactor tube and heated to 800 to 1,200° C. from the outside via the reactor tube walls to induce an endothermic reaction and thereby a steam reforming chemical reaction between the steam and the liquid biofuel. By setting the molar ratio of the fed steam and carbon in the liquid biofuel ([H2O]/[C]) at 0.3 or higher, a synthetic gas having a good composition that is virtually free of tar and soot and is primarily H2 and CO is obtained.

A method of burning fuel with lowered emission of nitrogen oxides comprises feeding pulverized fuel to the main burner in a combustion furnace and additionally feeding pulverized fuel to the region of the furnace where the first fuel is about to conclude its combustion, using inert gas with or without a low oxygen content as a conveying fluid, while supplying oxygen or air to a region downstream of the region for fuel addition.
