STEAM GENERATOR FOR BUSINESS USE

摘要

PROBLEM TO BE SOLVED: To provide a convenient steam generator for business use which is excellent in thermal efficiency and takes a short start-up time for beginning to blow steam. SOLUTION: A half front section of a water storage tank (T) is formed in an inverted U shape in a front view which is composed of a pair of vertical right and left side faces (31a) (31b) and a backward rising slant platform bottom face (32), just under which position a gas burner (G) is fixedly installed. Back end outlet section of submerged heat-transfer pipes (61) for heat exchange which are installed in parallel in the back half section inside the tank (T) under a submerged condition, is made to open to an exhaust guiding duct (59). Accordingly the combustion gas from the gas burner (G) is set to flow via the slant platform bottom face (32) of the tank (T) and to be let automatically circulated into the submerged heat-transfer pipes (61) by a guidance effect of the slant platform bottom face (32).
