How does combustion occur?
Combustion Combustion occurs when fossil fuels, such as natural gas, fuel oil, coal or gasoline, react with oxygen in the air to produce heat. The heat from burning fossil fuels is used for industrial processes, environ- mental heating or to expand gases in a cylinder and push a piston.
How do you calculate combustion efficiency?
Combustion efficiency calculation Combustion efficiency is expressed as a percent and determined by subtracting individual stack heat losses, as percents of the fuel’s heating value, fr om the total heating value of the fuel (100%). Dry gas loss and latent heat loss due to H2in the fuel are typically the largest sources of stack loss.
What are the parameters that are commonly examined in a combustion process?
Parameters that are commonly examined include: • Oxygen (O2) • Carbon Monoxide (CO) • Carbon Dioxide (CO2) • Exhaust gas temperature • Supplied combustion air temperature • Draft • Nitric Oxide (NO) • Nitrogen Dioxide (NO2) • Sulfur Dioxide (SO2) Oxygen, Carbon Monoxide and Carbon Dioxide
When should a combustion analysis be performed?
Combustion analysis should be performed on a warmed up unit at firing rates typical of normal operation. For systems with high, low and additional firing rates, adjustments should be made at all firing rates whenever possible. 8.
