Abstract

Combustion is a chemical reaction that occurs between a fuel and an oxidizing agent that produces energy, usually in the form of heat and light. During combustion, oxygen is combined with different elements of the fuel, like carbon, hydrogen, sulfur, etc. and produces the respective oxides. Some excess air is always supplied to the burner, to ensure complete combustion. Insufficiency in combustion air may result in lower combustion efficiency, fouling of the heat transfer surface, atmospheric pollution (unburned fuel, soot, smoke, and carbon monoxide), and flame instability. This chapter describes the different models of combustion chambers and gives a detailed description of the physical equations for each of them: modeling assumptions, fundamental equations, and correlations with their validity domains. A test-case is given for each component model that includes the structure of the model, the parameterization data, and results of simulation. It is a valuable aid to understand the combustion phenomena that govern the operation of power plants. It is a main support to develop models for industrial power plants. The full description of the physical equations is independent of the programming languages and tools.
