Forced-draught burner operating method - continues fuel supply for set period after turning off

摘要

The method operates a pre-mixing burner with fan, in which oxygen-carrier gas and fuel are mixed and delivered to a flame-holder. Fuel supply is shut off when the burner is turned off. Additional fuel is fed direct to the flame-holder (2), its supply continuing for a set period after the main fuel supply to the burner is shut off. USE/ADVANTAGE - Minium generation of harmful products on turning burner off.
