BURNER SYSTEM AT HEATING UNIT

摘要

A burner system, for example at a heating unit, comprising a burner of evaporation type for liquid fuel, for example Diesel oil, where fuel is intended via an inlet (5) to be supplied into a combustion space, preferably at the bottom (3) thereof, which combustion space preferably is substantially cylindric and open at the end (4) opposite to said botom (3), and where preferably an ignition member (6), for example a glowing filament, is provided for the initial ignition of evaporated fuel, and where means (9, 16, 17, 18) are provided for the supply of air to the combustion space. The burner system is particularly characterized in that at least one turbulence generating member, a turbulator (10), for example in the form of a central piece (11) or the like with blades, wings (12) or the like substantially radially projecting therefrom is located substantially perpendicularly to the longitudinal, vertical axis of the combustion space and substantially in parallel with said bottom (3), thereby dividing the combustion space into a lower space (13) and an upper space (14), and whereby an intimate mixing of air and fuel vapour is achieved at the passage past the turbulator (10). A further characterizing feature is that first ring of apertures (15) or the like for the supply of air to said lower space (13) extends substantially in the circumferential direction of the wall (1) of the combustion space, and in a corresponding manner at least one additional, a second ring of apertures (16, 17, 18) or the like is provided for the supply of air to said upper space (14).
