Abstract (en)
[origin: JPH05248705A] PURPOSE: To constitute a vortex motion zone in a mixed pressure chamber housing, while a high-temperature core part in the zone of a burner is surrounded by an air layer, where gas which flows backward is cooled to generate uniform thermal radiation in large space by a radiation tube. CONSTITUTION: In a room-heating device, the radiation tube of a conduit system arranged at the upper part of space to be heated is connected to a mixed pressure chamber housing 1. In this case, the radiation tube is connected to a backward flow chamber 19 with a ventilator 10 and at the same time is connected to a mixing chamber 20 with flame tube 14 for surrounding a burner 2. The mixing pressure chamber housing 1 is formed in a double-volute shape. In this case, two cylindrical parts form the housing, front and back plates 3 and 4 have double-vortex shapes, and connection tubes 18 and 21 to the radiation tube are connected to the back plate 4. A drive unit 5 for a burner 2 and the ventilator 10 is arranged on the front plate 3.
