Potter & Somerton - Chapter 13: Combustion

Prior to reading this Chapter we need to review Sections 12.1, 12.2, and 12.3 of Chapter 12 (Mixtures and Solutions), since both the reactants and the products of combustion are considered as mixtures of ideal gases. This will introduce us to the defimition of mole fraction and methods of volumetic analysis (including evaluation of partial pressures using the Dalton model), as well as the definition of mass fraction and methods of gravimetric analysis.

The entire Chapter 13: Combustion includes 3 sections, all of which are included in our syllabus. We will definitely cover Section 13.1: Combustion Equations including concepts of stoichiometric (or complete) combustion, incomplete combustion, % theoretical and % excess air, air-fuel (AF) ratio, and dew point of the products of combustion.

Section 13.2: Enthalpy of Formation, Enthalpy of Combustion, and the First Law allows us to determine the amount of heat transfer during the combustion process, and Section 13.3: Adiabatic Flame Temperature allows us to determine the temperature of the products of combustion. We will cover as much of these two Sections as time permits.

We recommend that you attempt as many as possible of the following Supplementary Problems during this week:

• Review Section Chapter 12.1 through 12.3: Problems 12.14 through 12.32
• Section 13.1: Problems 13.12 through 13.32
• Sections 13.2 and 13.3: Problems 13.33 through 13.51

All answers to the Supplementary Problems are given at the end of the chapter (Not yet checked).
