Flame temperature of coal
In daily life, the vast majority of flames one encounters are those caused by rapid oxidation of hydrocarbons in materials such as wood, wax, fat, plastics, propane, and gasoline. The constant-pressure adiabatic flame temperature of such substances in air is in a relatively narrow range around 1950 °C. This is mostly because the heat of combustion of these compounds is roughly proporti… Web34 rows · Flame Temperatures - Gases - Adiabatic flame temperatures for common fuel gases - propane, ...

WebIt is shown that, because of the reduced flame temperature, the wall heat flux in the coal switching cases (Cases 2 and 4) is considerably lower than that of Case 1. In Case 4, because tilting the burner down extends the high-temperature flame deeper into the furnace space, its wall heat flux appears higher than that of Case 2.
