A power plant including a coal-fired boiler, having a boiler space, heat exchanging means for generating steam, one or more air ports and exhaust means. The power plant also includes an internal combustion engine having an exhaust means, wherein the exhaust means of the engine are connected to the air ports of the boiler. A thermal NOx reduction system is disposed in the boiler for reducing the NOx content of both the internal combustion engine and boiler emissions. The engine further includes water cooling means, and heat is transferred from the engine to the heat exchanging means for generating steam. The exhaust means are connected to the boiler space either by secondary air ports adjacent or surrounding the coal nozzles of the boiler, by overfire air ports, by underfire air ports or by any combination of these ports. Means are preferably provided for removing SO2 and particulate pollutants from the exhaust of the boiler. |
