Abstract: 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.

Abstract: A heating and cooling system for an internal combustion engine comprising a heat storage circuit and a radiator circuit, and a method of controlling such a system are disclosed. The heat storage circuit comprises a heat storage container in which engine coolant is stored and allowed to flow into and out of. The radiator circuit comprises a radiator for flow of the engine coolant, and the radiator has a radiator inlet connected via an upstream radiator conduit to a coolant outlet of the engine, and a radiator outlet connected via a downstream radiator conduit to a coolant inlet of the engine. A bypass conduit is connected between the upstream radiator conduit and the downstream radiator conduit to allow coolant to bypass the radiator. A thermostat controlled valve is arranged in the upstream radiator conduit at a coolant outlet of the engine and connected to the bypass conduit.
