  • Method to improve the performance of low-NOx burners operating on difficult to stabilize coals
    Patent number: 4932337
    Abstract: 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.

  • Apparatus and method of reducing nitrogen oxide emissions
    Patent number: 4779545
    Abstract: An apparatus and method for reducing nitrogen oxide emissions from furnace flue gas is provided in which a pulse generator introduces natural gas, or other fluid fuel which has little or no fixed nitrogen, into the upper portion of the furnace. The fuel pulse reacts with the nitrogen oxide in the flue gas to form ammonia-like compounds and nitrogen gas. These ammonia-like compounds react with additional amounts of nitrogen oxide in the flue gas to form nitrogen gas, water vapor and carbon dioxide. In this manner, the amount of nitrogen oxide in the flue gas is reduced using a process which can be easily applied to retrofitted furnaces.
