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 () for biomass operates entirely by biomass and the heat source thereof does not depend on fossil fuel. A coarsely-ground powder biomass () subjected to gasification and gasification agent () are introduced to a primary gasification reaction room () and generate gasification reaction by, as reaction heat, radiation heat from a wall face of the primary gasification reaction room () heated by combustion gas () generated in the high-temperature combustion gas generation apparatus () and are dissolved. Consequently, the biomass () is converted to clean and high-quality generated gas.

Biomass gasification apparatus

Methanol is synthesized from a gas produced through gasification of biomass serving as a raw material, making use of a biomass feeding means for feeding biomass into a furnace main body and, located above the biomass feeding means, combustion-oxidizing-agent-feeding means for feeding into the furnace main body a combustion-oxidizing agent containing oxygen or a mixture of oxygen and steam.

Method for producing pulp by using an alga containing cellulose in the cell wall and having the long algae body with the ratio of length to width being 10 to 200 as an ingredient by giving no special treatment or by giving a simple bleaching treatment to produce pulp.

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.

Method of burning fuel with lowered nitrogen-oxides emission

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.
