Title: Heater in which burnt gases pass through doubled-back tube - excessive temperature difference at open end is produced by holes in inner wall
Inventor: WARD TREVOR
IPC: F23C3/00
Filed: 1974-10-15
Abstract: Gas (or vaporized fuel) diffuser burner is enclosed in a double-walled tube in such a way that all the combustion products pass right along the inner tube, and then back through the whole annular space between the walls, before they escape. Thus, at one end of the double tube, both the hottest, burning gas and the coolest, ready-for-discharge combustion products are separated only by the inner wall of the double tube. The steep temperature gradient producing stresses is eliminated by the holes (36) made in the inner wall of the tube, so that part of the burning gas can pass (still burning) directly into the space between the walls (16, 12) and reduce this temperature difference.
