FIELD: water boiling; boiler plants. ^ SUBSTANCE: water boiler has fire-chamber and convectional chamber which are both formed by screens made of pipes connected together by by-passing jet, disposed tangentially to axes of screen pipes. Convectional part is mounted above fire part. Screens of fire chamber are made of pipes disposed in vertical. Screens of convectional part are made of pipes disposed horizontally. Bypassing jets, which connect ends of pipes to follow staggered order, are parallel to plane of screen. One side of jets is disposed at angle to plane of screen, the other part is disposed tangentially to surfaces of pipes and in parallel to plane of screen. Method of making water boiler is based upon mounting of case of the boiler, preparing of short and long pipes, cutting windows at the ends of short pipes for connecting bypassing jets, mounting of bypassing units from short pipes, bypassing jets and bases, mounting of screens by means of welding of long pipes and bypassing units and mounting fife chamber and convectional chamber of boiler's screens. ^ EFFECT: improved efficiency of heat exchange; improved manufacturability. ^ 10 cl, 2 dwg |
