摘要： A method is disclosed which overcomes the problems which tend to occur in application low-NOx burners to coals in which the volatile matter is low in heat content. A gaseous or volatile liquid fuel is introduced into the ignition zone and/or the primary flame immediately downstream of the burner. This fuel will have the same effect as increased quality and quantity of the volatile content of the coal.

摘要： Disclosed is a process for combustion of carbonaceous substances containing ash and sulfur in slagging combustors wherein the fraction of sulfur retained in the slag is enhanced, emissions of nitrogen oxide are reduced, and operating problems with the furnace are avoided. The process comprises control of slag within a temperature range of 2000.degree.-2500.degree. F., slag stoichiometry less than oxidizing, and gas phase stoichiometry near stoichiometric.
