Combustor

Abstract

A combustor according to the present invention comprises: a combustion chamber having a grate provided therein and a combustion space formed above the grate; a fuel supply part downwardly connected tothe center part of the grate so as to supply fuel to an upper part of the grate; an air supply part connected to a side part of the combustion chamber so as to be slanted on a horizontal plane, thereby supplying combustion air such that combustion air swirls in the combustion space; a guide member disposed to protrude toward the inside of the combustion space from an inlet through which the combustion air flows into the combustion space, and opened downward so as to guide the combustion air such that the combustion air, provided by the air supply part, swirls downward along an inner wall of the combustion chamber in the combustion space; and protruding guide lines having a screw line shape and extended to be slanted downward on at least one of the respective surfaces, which face each other, from the guide member and the inner wall of the combustion chamber.

Description

technical field [0001] The present invention relates to combustors, and more particularly to combustors that recover the heat of combustion generated by the combustion of solid fuels in a combustion chamber for use as energy. Background technique [0002] Generally, in industrial facilities requiring industrial hot water, steam, or high-temperature gas, thermal energy is obtained using burners that generate thermal energy by igniting and burning fuel in a combustion chamber. From the standpoint of economy and resource recycling, solid fuel obtained from household waste, etc., has been widely used as the fuel used in such burners. [0003] However, in the process of burning the solid fuel as described above, ambient air having a relatively low temperature is simply supplied to the ignited solid fuel so that the solid fuel can be burned. Therefore, an increase in combustion efficiency may be limited. [0004] In addition, even if the burner is made to be durable, the tempera...

Therefore, the increase in combustion efficiency may be limited

[0004] In addition, even if the burner is made to be durable, the temperature inside the combustion chamber may be close to 1000° C. or higher in terms of durability, and thus such a high temperature may cause the configuration of the combustion chamber, especially The inner wall of the combustion chamber is damaged

As a result, the service life of the equipment may be reduced and continuous operation of the burner may be difficult due to the need to replace damaged parts of the combustion chamber
