PURPOSE:To enable the provision of a harmless frost proofing combustion device, by filling a flat container with gas containing no noxious component and mounting a spray type injection nozzle to an emission port. CONSTITUTION:A reverted V-shaped or a reverted conical top cover 11 engages with a heat emission port 12 of a square conical combustion cylinder 8, and the device is constituted such that the heat is dissipated at an angle of 45 deg. through a clearance between the heat emission port 12 and the reverted V-shaped or a reverted conical top cover 11. An engaging protruded part is provided on the inner upper peripheral wall of the lower connection of the square conical combustion cylinder 8, and a gas introducing pipe 2 having a screw thread is integrally secured at the center thereof and inwardly of a container-supporting cylinder having a nozzle at its upper end to form a burner. A forced pressure lever is connected to the gas emission hole of a flat type container 1, elastic bodies 1a mounted to the lower part are connected to a set lever and a plug control so that control of the emission hole is automatically performed, and is mounted to the central under surface of the gas introducing pipe connected to a combustion burner. |
