<p>The burner system, for liquid or gas fuel, has a burner with an atomiser jet and a support tube round it. It also has a combustion chamber consisting of a flame tube projecting into a boiler cavity and a mixing system with an open recirculation cross section. The combustion air is drawn in by a radial fan (24,30-33,40,41) operating in two stages, one through a first induction cavity (81) acting radially and one through a second induction cavity as a cross-flow blower. The second induction cavity is sealed off from the first one.</p> |
