| Abstract: | The interchangeability and flame stability of fuel gases are becoming important tasks in the fields of combustion science and technology, since the categories and characters of fuel gases have changed in a wide range. The interchangeability for boilers and industrial heating furnaces is investigated on three aspects: flame stability, heat intensity and flue gases flux. The criteria for the interchangeability of combination gases (BFG+COG) with coke oven gases (COG) are presented.The influence of fuel gases concentration and ambient temperature on combustion velocity and time are studied. The methods of stabled and enhanced combustion are discussed. On the basis of a lumped parameters model the mechanism of bluff-body' s flame stability is proven. |
