Abstract: A primary air system for a combustion plant provides a flow of primary air to at least one coal pulverizer, which emits pulverized coal in a downstream direction to a furnace. The primary air system includes a first primary air line for feeding hot primary air to the coal pulverizer and a second primary air line for admixing of cold primary air into the hot primary air line at a mixing location positioned upstream of the coal pulverizer. A control system shuts off the flow of primary air to the coal pulverizer, when the coal pulverizer is being repaired or serviced while the furnace is in operation. The control system includes a first flow control butterfly valve disposed in the first primary air line at a position upstream of the mixing location and a second flow control butterfly valve disposed in the second primary air line at a position upstream of the mixing location. A shut-off butterfly valve, disposed in the primary air line intermediate the mixing location and the coal pulverizer, includes a tandem wing supported at a cental location and movable between an open position and a closed position. The tandem wing has parallel, first and second wings forming a space therebetween. A pressure relief line provides fluid communication with the space between the first and second wings when the tandem wing is in the closed position. A pressure relief butterfly valve is disposed in the pressure relief line.

Abstract: The subject invention relates generally to methods and apparatuses for calcining gypsum. The apparatuses and methods place a gypsum particle optimizer in close association with the impact mill so that all the gypsum supplied to the impact mill has to enter the gypsum particle optimizer prior to the gypsum entering the impact mill, and so that heat generated from the impact mill enters into the gypsum particle optimizer from the impact mill. The gypsum particle optimizer utilizes a rotor to disperse the gypsum throughout the gypsum particle optimizer so that the gypsum is exposed to the heat from the impact mill prior to entering the impact mill. The exposure to the heat removes free water from the gypsum prior to the gypsum entering the impact mill.

Abstract: A fossil fuel fired combustion apparatus and a method for operating the fossil fuel fired combustion apparatus are provided which offer the flexibility to use carbon dioxide (CO2) both as a desirable end product and as support to the combustion process. The method includes the step of introducing a substantially pure oxygen feed stream into the fossil fuel fired combustion apparatus and the step of combusting a fossil fuel in the presence of the substantially pure oxygen feed stream to produce a flue gas having carbon dioxide and water vapor as its two largest constituent elements by volume. The method also includes the step of passing the flue gas through an oxygen feed stream pre-heater at which heat from the flue gas is transferred to the oxygen feed stream. Furthermore, the method includes the step of separating the flue gas into an end product portion and a recycling portion. The method additionally includes cooling and compressing the end product portion of the flue gas so as to yield carbon dioxide in a liquid phase and directing the recycling portion of the flue gas to the fossil fuel fired combustion unit to contribute to the combustion process therein.

Abstract: Provided is a method for operating a pulverized coal-fired boiler facility, wherein upgraded low-grade coal can be safely used as fuel and an existing facility needs little remodeling. The present invention relates to a method for operating a pulverized coal-fired boiler facility (100) that uses upgraded brown coal as fuel. Boiler exhaust gas taken out of an exhaust gas duct (31) is added to air from a primary air fan (10) to prepare mixed gas with an oxygen concentration of less than 12% in a volume ratio, the mixed gas is caused to separately flow to a carrier gas duct (33) that goes through a GAH (8) and a bypass carrier gas duct (34) that bypasses the GAH (8), and thereafter the mixed gas is supplied to a mill (21).
