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.

Biomass gasifycation furnace and system for methanol synthesis using gas produced by gasifying biomass

A burner for combustion of a pulverized coal mixture having two kinds of rich and lean concentration has, a height of a burner panel reduced and the overall burner simplified. A rich/lean separator (10, 20, 30) is provided within a pulverized coal conduit (2) so that a high concentration mixture is formed in an outer peripheral portion and a low concentration mixture is formed in a central portion within a single pulverized coal conduit. Thus, a rich mixture burner and a lean mixture burner, which have been conventionally provided separately, may be formed into a single burner. Recirculation of air is accelerated by a cutaway slit (20d, 30d) provided in a central portion of the rich/lean separator to make the air flow rate distribution uniform in a pulverized coal nozzle. Also, a duct and an air blow box for the combustion air to be supplied to the pulverized coal flame are not integrally formed continuous in the height direction, but are divided into a plurality of discontinuous units.
