FUELS AND COMBUSTION 31 Introduction to Combustion
Combustion is the conversion of a substance called a fuel into chemical compounds known as products of combustion by combination with an oxidizer The combustion process is an exothermic chemical reaction, i e , a reaction that releases energy as it occurs Thus combustion may be represented symbolically by: Fuel + Oxidizer Products of

Combustion Chemistry Basics •Combustion involves the oxidation of a fuel, ideally leading, for an organic fuel such as octane or ethanol, to the formation of carbon dioxide and water, with the release of heat •The overall chemical equation, e g C 2 H 5 OH + 3 5O 2 2CO 2 +3H 2 O does not describe the way in which the reaction occurs

combustion intensity) Since various combustion modifications for NOx reduction can produce one or more of the above conditions, the possibility of increased CO emissions is a concern for environmental,
Combustion Analysis of Gas and Oil Appliances
perform a combustion analysis during routine service, or any time changes are made that will affect the combustion process This can be as simple as adjusting an air shutter, changing gas pressure or as involved as changing an oil nozzle A combustion analysis is performed for four primary reasons: 1

combustion temperatures and, hence, contribute to lower NOx emissions In addition, the partially staged combustion that naturally occurs in all stokers due to the use of underfire and overfire air contributes to reduced NOx emissions relative to PC-fired units The low operating temperatures
Fundamentals of High Pressure Combustion
combustion research, such an assumption can lead to very large errors in high pressure combustion systems For example, Fig 2 illustrates that the compressibility factor, Z = P/(ρRT) (where T is the mixture temperature and R is the mixture specific gas constant), can be as small as ≈ 0 35 for dodecane under practical operating conditions

C5 PCB Combustion - US EPA
• Combustion criteria shall be either: 2 second dwell time at 1200C ± 100C and 3 excess oxygen in stack gas; or 1 5 second dwell time at 1600C ± 100C and 2 excess oxygen in stack gas (only applies to liquid PCBs) • Combustion Efficiency of at least 99 9 • Measure feed rate and quantity of PCBs fed and record at intervals of every 15
