Patent EP-0322678-A2 (EP)
Inventor: JENKINS DAVID PAUL
IPC: F27D99/00
Filed: 1988-12-16
Abstract: A regenerative burner system comprises two burners alternately fired and each having an air and fuel supply thereto traversing separate heat exchangers. The arrangement is such that the hot gases exhausted from the furnace during firing of the one and the other burners traverse the heat exchangers associated with the other and the one burners, respectively, relinquishing heat thereto whereby both the fuel and the air supply to each burner extracts heat from its associated heat exchanger during the firing cycle of that burner. 
     By heating both the fuel and the air input to the regenerative system, fuels of low calorific value, e.g. blast furnace gas or any gases low in or devoid of hydrocarbons may be efficiently utilised to provide a stable high temperature flame without the need for enrichment with 'pilot' fuels.
