Combustion Apparatus For Recovering Heat

Abstract

A combustion apparatus for recovering heat according to the present invention comprising a combustion tank for burning fuel contained in the interior by combustion air supplied from the exterior, characterized in that: a combustion chamber surrounded by an inner wall for burning fuel is defined in said combustion tank; a swirl flow supply chamber for supplying a combustion air into said combustion chamber is defined around the outer circumference of the inner wall of said combustion tank; a combustion air supply passage for supplying combustion air from said swirl flow supply chamber into said combustion chamber is defined on the inner wall of said combustion tank; said combustion air supply passage is slanted at a predetermined angle to the vertical direction of the inner face of the inner wall in said combustion tank; and the combustion air generates a swirl flow in the combustion chamber. Furthermore, the combustion apparatus for recovering heat according to the invention characterized in that; an air cooling chamber for supplying combustion air supplied from the exterior into said swirl flow supply chamber is defined around the outer circumference of said swirl flow supply chamber in said combustion tank, and the combustion air supplied from the exterior is supplied through said cooling chamber into the swirl flow supply chamber to decrease a heat loss and to improve a thermal efficiency.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims the priority benefit of Korean Patent Application No. 10-2007-0117458 filed on Nov. 16, 2007, the contents of which are hereby incorporated by reference as if fully set forth herein in their entirety.STATEMENT CONCERNING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT[0002]Not applicable.FIELD OF THE INVENTION[0003]This invention relates to a combustion apparatus for recovering heat, more specifically to a combustion apparatus for recovering and utilizing the combustion heat generated in a combustion chamber in which solid fuel is burned.BACKGROUND OF THE INVENTION[0004]Generally, in industrial facilities required for industrial hot water, steam, or high temperature gas, a combustion apparatus is used for generating heat energy by the combustion of fuel in the interior of a combustion tank in order to achieve heat energy, and as a fuel in this combustion apparatus, a solid fuel such as RDF (fuelized life waste) or RPF (...

AI Technical Summary

Benefits of technology

[0016]According to the present invention, a combustion apparatus for recovering heat is provided which is manufactured at a less expensive cost, and is capable of improving the thermal efficiency and reducing the generation of environmental pollution.

Problems solved by technology

But, this type of prior art combustion apparatus, in which plenty of solid fuel is inputted to the lower part of a combustion tank and burned, has a problem resulting in the waste of materials due to incomplete combustion of the fuel.

Also, it is disadvantageous in that, since a plurality of ashes remain at the same time, it is impossible to process the automatic disposal of these remaining ashes.

Furthermore, once the first combustion is finished, the next combustion is processed after a desired quantity of fuel is inputted again and is ignited, therefore, it is difficult to attain a continuous combustion process and the caloric value is not uniform.

Moreover, the combustion of this solid fuel results in exhausting much gas or particles such as dust, carbon monoxide, smoke, gas phase HCL, SOx, NOx, dioxin and the like which give rise to environmental pollution.
