Development of Combustion Data to Utilize Low-Btu Gases as Industrial Process Fuels. Project 61004Special Report No. 5:Flat-Flame Burner.

摘要

None of the substitute fuel gases could be directly retrofit on the burner with a flat flame. In order to produce a flat flame,the burner would have to be modified to change the air/fuel velocity ratio. Since there is no room to enlarge the fuel flow area,the airflow area would have to be decreased. To maintain a fuel input rate of 3million Btu/hr would require the air pressure to be increased by a factor of at least three (from 20to 60ounces),to supply the necessary air. Assuming instead that the combustion air fan remained the same,the fuel flow would have to be reduced. The fuel input would be reduced from a level of 3million Btu/hr to 2million Btu/hr for KTO.
