Granted: 2001-12-01
Abstract: Disclosed is a combustor capable of generating energy of high heat with a small amount of fuel and suppressing the generation of noxious gases produced in the course of burning, when generating thermal energy by burning fuels. The combustor consists of a combustion tub (10) of a cylindrical shape. This tub (10) has an exhaust opening (2) on its upper wall, and an air inlet hole (3) on its rear central portion. The inlet hole (3) is coupled with an air inlet pipe (7), while a modified water supply pipe (4) and a fuel supply pipe (5), both having an annular shape and a plurality of radial discharge ports on their inside surfaces. The combustion tub (10) may be designed to have a small diameter at its upper portion and a large diameter at its lower portion or to have a large diameter at its upper portion and a small diameter at its lower portion. This tub (10) also may be received within an outer cylinder (11) while maintaining an annular space S between them, with the air inlet hole (3) being formed at a rear central portion of the cylinder (11). With this configuration, emission of noxious gases (such as carbon monoxide, nitrogen oxide, smoke, etc.) can be almost completely eliminated because the fuel is almost perfectly burnt, resulting in smoke-free and odorless combustion, when burning the fuels for heating rooms, thereby preventing environmental pollution. Further, since the combustor saves fuels, it is economical. The combustor of this invention accomplishes combustion of high temperature with a consumption of a small amount of fuel, and so the operational efficiency of this combustor is improved.
