초록 ▼

A method of using internal combustion engine exhaust in a combined cycle power plant is disclosed, wherein the quality and distribution of exhaust to the boiler space of a steam generated electric power plant is controlled to achieve greater system efficiencies, and wherein exhaust pollutants are reduced. Outside air is blended only with that portion of the exhaust that passes through the burner ports as secondary or higher level combustion gas. The remainder of the exhaust is provided to the boiler space by a route other than through the burner. The highest overall system efficiencies are achieved where the amount of outside air blended with the portion of exhaust that passes through the burner is such that the blend contains about the minimum amount of oxygen required for complete and stable combustion of the selected fuel, where a substantial percentage of the total exhaust is routed to the boiler space by a route other than through the burner, and where the amount of fuel is sufficient to achieve a desired boiler entering temperature upon its combustion. Pollutants are reduced by combinations of staged reburning, Selective Non-Catalytic Reduction, and Selective Catalytic Reduction processes applied at various points along the combustion and exhaust path.

1. A method of operating a power plant which includes an internal combustion engine, a burner and a boiler space, comprising the steps of:routing a first portion of exhaust from the internal combustion engine to the burner; adding fuel to said first portion in order to form a first mixture; adding air to said fuel and said first portion of engine exhaust in order to form said first mixture; preheating said air prior to its being added with said fuel to said engine exhaust in order to form said first mixture; combusting said first mixture in a primary combustion zone, thereby creating a burner exhaust; routine a second portion of said engine exhaust from the internal combustion engine to mix with said burner exhaust, thereby creating a second mixture; combusting said second mixture in a secondary combustion zone creating a secondary burner exhaust; and transferring the heat from said secondary burner exhaust to feedwater and steam in order to create steam. 2. The method of claim 1, further comprising the step of:adding fuel to said second mixture prior to said second combusting step. 3. A method of removing pollutants from the exhaust of an internal combustion engine by substoichiometric staged reburning comprising the steps of:mixing fuel and a first portion of said engine exhaust to create a first mixture; adding air to said fuel and said first portion of engine exhaust in order to form said first mixture; preheating said air prior to its being added with said fuel to said engine exhaust in order to form said first mixture; combusting said first mixture, creating first stage exhaust; mixing a second portion of said engine exhaust with said first stage exhaust to create a second mixture; combusting said second mixture, creating a second stage exhaust; mixing an oxygen rich stream with said second stage exhaust to form a third mixture; spontaneously combusting said third mixture, creating a bulk mixture; lowering the temperature of said bulk mixture; and allowing said bulk mixture to escape into the atmosphere. 4. The method of claim 3, further comprising the step of:adding fuel to said second portion of engine exhaust and said first stage exhaust to create said second mixture prior to said second combusting step. 5. The method of claim 3, further comprising the step of:adding fuel to said second mixture prior to said second combusting step.
