Existing High-temperature Air Generator is air and the gaseous mixture of combustion gas is directly burnt, premixed or
Premixing effect is not good, easily causes the consequence of the insufficient and combustion instability that burns.Especially, for mixed gas as fuel
High-temperature gas generating meanss because the various gas compositions of enterprise's side-product are not fixed, with composition change its heat
Value is also changed therewith.And the method for the control mixed gas of routine is only to maintain the certain volumetric mixture ratio of each coal gas, mix
After conjunction the calorific value of coal gas still fluctuate frequently, amplitude it is larger.And the wave characteristic of mixed gas calorific value, combustion instability can be caused very
To flame-out situation.
Therefore, develop that a kind of premixing effect is good, occur stable burning to be remained to frequently and during larger fluctuation suitable for calorific value, and
And the sufficient new type high temperature gas generating unit that burns is very necessary.
