Backfire thermal utilization possession oxygen ardor conversion reignition type burner

摘要

PURPOSE: To simplify the structure of a burner and enhance combustion efficiency by afterburning and circulating repeatedly an imperfect combustion gas which is ejected from a gas ejection hole of an inner combustion cylinder into an outer combustion cylinder with back fire of a heating gas and heating the inner combustion cylinder. ;CONSTITUTION: The rear side in a combustion cylinder 1 is turned into a decompression section by a compressed air (a) which is supplied from an air supply duct to the an outer cylinder 1, which forces the compressed air (a) to flow back along the outer periphery of an inner combustion cylinder 15 so that the compressed air is mixed with an imperfect combustion gas (g) which is injected from the inner combustion cylinder 15 in the outer combustion cylinder 1. The mixed gas is repeatedly circulated through the outer combustion cylinder 1 and turned into a high temperature gas, thereby promoting thermal vaporization. The imperfect combustion gas (g) which is ejected from the inner combustion cylinder 15 is heated with the back fire of the high temperature gas circulating around and ejected outside from a gas discharge cylinder 7 as a high temperature perfect gas. This construction makes it possible to enhance the combustion efficiency in small size and low weight structure.;COPYRIGHT: (C)1993,JPO&Japio
