Burner arrangement with separate inlet for fuel and combustion air into combustion chamber

摘要

The burner arrangement consists of a coaxial pipe on one end of which the inner pipe (18) opens into one or more supply pipes (5) for the combustion air, and the outer pipe (22) opens into one or more supply pipes (4) for the fuel or fuel and air mixture. The other end of the coaxial pipe has a combustion air distributor (7) tightly joined to the inner pipe. At least one row (12) of fuel nozzles (13) close the cylinder ring between the outer and inner pipe. The distributor has a closed top (9) and open bottom (8) part and outlets (11). The burner is contained in the combustion chamber (2). The volume and geometry of the combustion zone matches those of the empty space (1) defined by an outer wall (3) which has a discharge gas outlet (6), and by the outline of one or more distributors.
