    Abstract: A power generating combustion system and method are provided with a first stage combustion system that may include a wet oxidation reactor or a direct contact boiler and a second stage combustor including a stoichiometric burner to produce the substantially complete combustion of a wide range of fuels and mixtures of fuels to produce combustion products usable in generating power. The system design temperatures and pressures allow the substantially complete combustion of garbage, municipal and industrial waste and low quality fuels to generate power.

    Abstract: A method for operating a coal dust furnace comprises blowing into the furnace a mixture of combustion air and combustion coal dust having a specified range of grain sizes, the range of grain sizes having an upper limiting grain size, and, for reducing the temperature of the flame, also blowing into the furnace additional temperature reducing coal dust, the range of grain sizes of the additional coal dust lying essentially above the specified upper limiting grain size, this temperature reducing coal dust subsequently being burnt in additional areas of the furnace. The two types of coal dust are blown into the furnace in concentric streams each surrounded by an annular stream of its associated combustion air. If the combustion coal dust is the central stream, then its combustion air is fed in a swirling stream.

    Abstract: A method of operating a furnace for minimizing the formation of NOx and SOx in combustion gases comprises (a) conveying a pulverized coal in an air stream towards the furnace, and (b) separating the stream into a fuel rich portion and a fuel lean portion. The fuel rich portion is introduced into the furnace in a first zone. The fuel lean portion is introduced into a second zone in a quantity such that there is excess air over that required for combustion of all of the fuel within the furnace.

    Abstract: In a burning air feeding device (9) of alternating heat-exchanging type, the feed of burning air and the discharge of a burned exhaust gas are performed at the speeds of 80 to 200 m/sec. A burner structure (4) is constituted such that a low-calorie fuel gas is preheated with the heat of a precombustion high-calorie fuel gas till the low-calorie fuel gas reaches a mixing starting zone (CA), and such that the precombustion high-calorie fuel gas and the low-calorie fuel gas are burned together in the mixing starting zone (CA). The sum (Q1 + Q2) of an air quantity (Q1) fed from the hot air feeding ports of a plurality of fuel gas burning devices and an air quantity (Q2) of a precombustion air to be mixed with the high-calorie fuel gas in the plural fuel gas burning devices is set to 1.02 to 1.10 times as high as the stoichiometric air quantity (Qs) necessary for the combustion, and the ratio (Q2/(Q1 + Q2)) is set within the range of 0.011 to 0.047.
