Burner for liquid or gas fuel

摘要

The burner consists of an air intake casing (1) with penstock (2). The casing is connected by air outlet apertures to the cavity of a flame tube (5). The burner is arranged so that the air outflow apertures spaced round the fuel output aperture (6) of the penstock are at different distances from the flame tube wall. The flame tube cavity is divided into an air-gas flow cavity and at least one exhaust gas return flow cavity (8) at one side of and parallel to the air-gas flow cavity.
