Abstract (en)
[origin: EP0866270A2] To the burner zones combustion air is fed by a blower and combustion gas is fed in a regulated fashion via individual conduits. The combustion air like the combustion gas is fed to each burning zone (22a, b, c, d) via a single channel (24a, b, c, d). In a main conduit (32) feeding all combustion gas individual conduits (58a, b, c, d) a gas/air compound regulator controlled by air volume flow is installed. For connecting and disconnecting the gas feed to individual burning zones (22a, b, c, d), on/off valves are provided in the corresponding combustion gas individual conduits (58a, b, c, d).
