摘要： A method for controlling emissions from a power plant having an ammonia injection grid that includes a plurality of ammonia injection points includes the steps of injecting ammonia into a flow of exhaust gas at an injection location, the injection of ammonia defining a spatial distribution of ammonia across an exhaust gas flowpath, measuring at least one parameter of the exhaust gas downstream from the injection location, comparing a measured value for the at least one parameter of the exhaust gas to a threshold value for the at least one parameter and, if the measured value for the at least one parameter exceeds the threshold value for the at least one parameter, automatically modifying the spatial distribution of ammonia injection across the exhaust gas flowpath.

摘要： A heat recovery steam generator includes a gas inlet for receiving a flow of exhaust gas from a gas turbine, a gas outlet opposite the gas inlet, at least one heat exchanger intermediate the gas inlet and the gas outlet, the heat exchanger having a plurality of heat transfer surfaces configured to transfer heat from the exhaust gas to a fluid within the heat exchanger, and a valve associated with the heat exchanger and configured to regulate a flow of the fluid through the heat exchanger. The valve is controllable from an open position to a closed position to decrease the flow of the fluid through the heat exchanger in order to effect an increase in a temperature of the heat transfer surfaces of the heat exchanger to clean the heat transfer surfaces.

摘要： A heat recovery steam generator includes a gas inlet for receiving a flow of exhaust gas from a gas turbine, a gas outlet opposite the gas inlet and configured to transport the flow of exhaust gas to atmosphere, and a sorbent injection device intermediate the gas inlet and the gas outlet, the sorbent injection device including at least one injection port configured to inject a sorbent into the flow of exhaust gas. The sorbent is configured to react with an acid gas within the flow of exhaust gas to neutralize the acid gas and inhibit the formation of salt deposits.
