Problems solved by technology

[0002] At present, in the existing open flame boilers or boilers, the bottom of the open flame is mostly flat or arc slightly concave or slightly convex, because the heated bottom is flat, the heating area is small, the open flame combustion stroke is short, and the combustion temperature is relatively low , it is difficult to maintain, and most of the heat energy after combustion is quickly dissipated into the surrounding air, resulting in low heat utilization rate, high energy consumption, and more exhaust gas

Abstract

An energy-saving heating apparatus using naked fire as its heat source features that an annular and deeply concave flame containing cavity is made on the bottom surface of its main body, the width of said flame containing cavity is increased outward to form an energy accumulating cavity, and several spiral slots with wide lower end and narrow upper end are made on the external surface, which are matched with external hood to form an afterheat utilizing system.

Description

[Affiliated technical field] [0001] The invention relates to a heating device, in particular to an energy-saving heating device using an open flame as a heat source. [Background technique] [0002] At present, in the existing open flame boilers or boilers, the bottom of the open flame is mostly flat or arc slightly concave or slightly convex, because the heated bottom is flat, the heating area is small, the open flame combustion stroke is short, and the combustion temperature is relatively low , It is difficult to maintain, and most of the heat energy after combustion is quickly dissipated into the surrounding air, resulting in low heat utilization rate, high energy consumption, and more exhaust gas. [Content of the invention] [0003] Aiming at the problems existing in the existing open flame heating devices, the object of the present invention is to provide an open flame energy-saving heating device that can significantly increase the heating area, prolong the combustion...
