Abstract: A combustion method applied to a water-tube boiler and a regenerator of an absorption-type refrigerator includes a concentration ratio adjusting step of adjusting a concentration ratio of nitrogen oxides, carbon monoxide, and oxygen in a gas from a gas generation source to a predetermined reference concentration ratio, and a hazardous-substance decreasing step of decreasing nitrogen oxides, using an oxidation catalyst having characteristics of decreasing the concentrations of nitrogen oxides and carbon monoxide on a secondary side to substantially zero when the concentration ratio on a primary side is set to be a reference concentration ratio, in which the concentration ratio adjusting step detects the concentration of oxygen on the secondary side of the oxidation catalyst to control the concentration ratio so that a detected oxygen concentration becomes a set oxygen concentration substantially close to zero. According to the combustion method, the emission amount of nitrogen oxides can be decreased to close to zero as much as possible, and the emission amount of carbon monoxide can be decreased to a permissible range. Further, the control of a concentration ratio can be performed stably by detecting the concentration of oxygen.

Abstract: An air separation unit is integrated with a power generating plant to improve the efficiency of power generation. The methods and systems improve the efficiency of power generation by utilizing liquid nitrogen from the air separation unit as the working fluid in a turbine. The liquid nitrogen is pressurized while in the liquid state. After warming the pressurized nitrogen stream by cooling the air for the air separator unit, the compressed nitrogen is expanded in a turbine to perform work. After expansion, the nitrogen is vented to ambient air. The nitrogen in its pressurized state can be used for energy storage and/or for smoothing out power demand on a power grid.

Abstract: The present invention is a method for reducing the slagging and fouling of the surfaces of the waterwalls, firebox, superheater, and reheater of the furnace of a coal-fired steam boiler. The process reduces the firebox exit temperature to below the specific ash melting temperature by injecting the following, either alone or in combination, into ports located in the upper section of the firebox: recirculated flue gas from downstream of the electrostatic precipitator, atomized water, or a sorbent water slurry. All of these materials have a lower temperature than the main flue gas or require additional heat for evaporation. Mixing these materials with the main flue gas from the furnace will not affect the coal combustion process, yet will reduce the temperature of any fly ash particles in the main flue gas to below the specific ash fusion temperature, and thus, prevent slagging and fouling within the furnace.

Abstract: A system for maintaining an optimal flue gas inlet to a boiler mounted SCR assembly in the flue of the boiler is accomplished by mixing the normal inlet feedwater to an economizer of the boiler with near saturation water from downcomers of the boiler to thereby raise the temperature of the flue gas passing across the economizer and raising the SCR inlet to the desired optimal SCR operation temperature.
