<p>The flame tube is closed at one end and is for use in gas firing systems. The fuel gas is burnt completely and uniformly over the burning surface. The combustion process is improved by providing the central flue gas tube (3) with guiding blades. The guide blades (4) project radially from the shell of the flue gas pipe (3). These guide blades are arranged at different angles relative to the gas stream. The flue gas reaches from the open end close to the closed end wall. Combustion takes place directly within the outside tube.</p> |
