Abstract: A method for reducing acid gas emissions from a carbonaceous fuel burning power plant. An aqueous potassium hydroxide dry scrubber method is used to reduce the formation of nitrogen oxides, sulfur oxides, hydrogen chlorides and hydrogen fluoride from plant flue gases. For those plants utilizing an electrostatic precipitator to remove particulate matter from the flue gas, the performance of this component is also enhanced by the injection of potassium hydroxide upstream of the component. As an added advantage, the final product has beneficial commercial utility as a fertilizer product, rather than having to be disposed in a landfill.

Abstract: A scalable pulse combustor that can be deployed as the heat exchanger in high efficiency, low NOx condensing boilers, water heaters and steam generators is provided. The combustor generally comprises an annular burner coil with a burner flange for accommodating the nozzle of a conventional burner/blower fitted into the central aperture thereof; a spaced-apart opposite annular spreader coil with a heat exchange hub fitted into the central aperture thereof; and a plurality of annular intermediate coils. Each of the burner, spreader and intermediate coils are preferably formed of spiral wound stainless steel tubing, with each winding directly abutting the preceding winding so as to create an annular wall. The heat exchange hub functions as a secondary heat exchanger with its own independently controllable coolant flow.

Abstract: The invention relates to a burner arrangement for a combustion chamber (12) in addition to an associated combustion chamber (12), in particular a gas turbine combustion chamber or a steam generator combustion chamber, comprising a plurality of burners (8), which are equipped for the combustion of fuel which contains carbon by supplying pure oxygen, which is effective as an oxidation agent. The aim of the invention is to obtain a burner arrangement which has a particularly high energetic degree of efficiency and particularly low residue emissions and at the same time maintains the construction and operation thereof simple and economical and reverts to suitable fuelling concepts. Also, the acceptable material temperatures of the encircling walls (6) surrounding the combustion chamber (12) must not be exceeded. The inventive first burner (8) is embodied in such a manner that the ratio (?), per time unit, of the amount of oxygen guided therein, in normal operation, for the stochiometrically required amount of oxygen is greater than for a second burner (8) which is arranged downstream from the direction of the flow of flue gas (14).

Abstract: An improvement of a combustion furnace for a boiler in which it is possible to improve and uniformize the heat collection ratio of the furnace of the boiler. Moreover, this invention easily controls the temperature of superheated steam while the heating surface area is kept constant without altering the boiler construction and heat balance, and provides a zone temperature control to a boiler. The boiler according to the present invention is provided with a radiant heat transfer portion (15) in which at least one or more heat accumulating type burner systems are disposed in which a pair of burners (2, 3) for suppyling air for combustion and exhausting combustion gas through a heat accumulator (5) are caused to burn in an alternate fashion while combustion gas is discharged through the heat accumulator (5) from one of the burners which is not burning, so that excess heat energy that has not been consumed in the radiation heat transfer portion (15) is recovered when it is exhausted via the heat accumulator (5) of the other burners. In addition, in the boiler of the present invention, a plurality of heat accumulating type burner systems (1) are disposed in a direction in which water for the boiler flows, and the pair of heat accumulating type burners (2, 3) of the respective burner systems (1) are disposed in a direction that intersects the direction in which water for the boiler flows, whereby a temperature zone is formed by controlling combustion for each heat accumulating type burner system (1), thereby making it possible to control the distribution of the furnace heat collection ratio. Furthermore, the boiler of the present invention has the radiation heat transfer portion (15) in which at least one heat accumulating type burner system is provided, and is provided with a superheater (17) in which saturated steam is superheated by extracting a part of combustion gas from the radiation heat transfer portion (15), the combustion gas being exhausted directly out of the combustion chamber without passing through the burners (2, 3).
