Heat-insulating structure for combustion equipment

摘要

Discloses a heat-insulating structure for combustion equipment of such a type that a burner element of combustion equipment is insertedly disposed at an installation opening of thermal equipment such as a boiler, with a view to simplified structure and enhanced workability. In combustion equipment (B) having a burner element (20) insertedly disposed at the installation opening (1) of the thermal equipment (A) via the support frame (30) a thermal insulator (50) flush with the burner element (20) on the thermal equipment (A) side is disposed between the installation opening (1) and the outer side face of the support frame (30).
