摘要： A method of operation of a thermal power plant having an air separation system with a plurality of air storage unit (ASU) compressors and a liquid oxygen/liquid air (LOX/LA) storage facility for oxyfuel firing of fossil fuel and a power plant having a control system to perform the same are described. The method is characterized by the step of controlling the net power output of the plant in response to short term variations in grid demanded net plant output by dynamically adjusting the works power of the ASU compressors preferably in conjunction with co-ordinated changes in firing demand. The method is in particular a method to produce an improved primary and secondary response to transient changes in grid demand and to provide accurate response to load dispatch ramps.

摘要： A control system for an oxy-fuel combustion process is disclosed for use with a boiler or furnace which dynamically controls the flame temperature of each burner involved in the combustion process to dynamically maximize the flame temperature. The boiler or furnace used in conjunction with the combustion process in accordance with the present invention is configured with a radiant, i.e. line of sight, heat zone and a convective heat zone. By dynamically maximizing the flame temperature of the various burners within the boiler or furnace, the radiant heat transfer is optimized. By optimizing the radiant heat transfer within the boiler or furnace, the efficiency of the boiler or furnace is significantly improved.

摘要： The Automatic Furnace is a method and apparatus for maintaining a desired CO, NO, or temperature range at the flue of a multiburner furnace to increase efficiency and decrease pollution and includes delivering a second oxidant dosage to the burner while repeatedly sequencing through the plurality of sequential flue parameter doses beginning with the first flue parameter dose and proceeding to an adjacent flue parameter dose in the sequence after a predetermined time interval has elapsed. The second oxidant dosage is delivered until the flue parameter level attains the desirable range, at which point corresponding oxidant and flue parameter doses are selected from the plurality of sequential oxidant doses and flue parameter doses. The method also includes delivering the selected oxidant dose and flue parameter dose so as to maintain the desired flue parameter range.
