Abstract
PURPOSE: To provide a good lining process by forming on the top end of an inner cylinder forming a water chamber a flange of which diameter is larger than a outter cylinder, fixing it by welding it together with a flange on the top of the outer cylinder and forming inside a glass lining layer.
CONSTITUTION: On the top end of an inner cylinder 1 having a combustion chamber inside, a flange 1a is formed by making its diameter larger than an outer cylider 2 by 2l and stretch outwardly over the outer cylinder. Thus formed flange 1a is joined together onto a flange 2a formed on the top end of the outer cylinder 2 by welding W in the neighborhood of the circumferential section and a glass lining layer a is formed inside so that a water chamber 3 is provided. An amount of l being the difference in diameter between the outer cylinder 2 and the flanges 1a and 2a is to be appropriately set so that oxide coating is not formed on the wall surface of the water chamber 3 by welding heat.
