A combustion burner includes a mixture nozzle (,) defining a mixture fluid passage through which a mixture fluid (,) containing pulverized coal and conveyor gas flows toward a furnace, secondary and tertiary air passages surrounding the mixture nozzle (,), through which secondary air (,) and tertiary air (,) for combustion purposes flow, respectively; and air injection nozzles (,) provided in the vicinity of an outer periphery of a distal end of the mixture nozzle (,). The air (,) is injected from the air injection nozzles (,) toward the axis of the mixture nozzle, so that the high-temperature gas in the vicinity of the outer periphery of the distal end of the mixture nozzle (,) is drawn into the mixture fluid (,) in the vicinity of the outer periphery of this distal end.

Combustion burner and combustion device provided with same

A burner apparatus for pulverized coal comprises a pulverized coal supply pipe, a starter oil burner extending within the pulverized coal supply pipe to define therebetween a tubular passage through which a mixture of combustion air and pulverized coal passes into a furnace, a flame holder provided at an outer periphery of one end of the pulverizerd coal supply pipe facing to the furnace, a cylindrical member disposed in the tubular passage for dividing a part thereof into two coaxial passage parts, and a valve adapted to close an axial end opening of the cylindrical member for varying a concentration of pulverized coal in a radial outer passage part of the coaxial passage parts.

A carbon monoxide-oxygen system fuel cell having overcome various drawbacks of such fuel cell and capable of using CO, as it is, as its fuel without employing any shift converters is provided, which fuel cell is provided with a diaphragm between an anode and a cathode to separate the two electrodes and characterized in using a solution containing at least a monovalent copper and a halide as a complexing agent for the copper, as the electrolytic solution for the anode, and reacting CO in the form of a carbonyl complex of the copper in the electrolytic solution.

Carbon monoxide-oxygen fuel cell

A combustion process for reducing nitrogen oxides in combustors is proposed wherein combustion takes place successively forming an incomplete combustion zone, a reducing combustion zone, and a complete combustion zone, respectively corresponding to primary burners, secondary burners and air ports or after-burners, successively arranged in the direction of gas stream in a furnace. According to the present invention, it is possible to reduce nitrogen oxides by improving a manner of combustion without providing any denitrating apparatuses for exhaust gas.
