Separated Combustion Burner For Preventing Clinkers

Abstract

The objective of the present invention is to provide a separated combustion burner for preventing clinkers, the separated combustion burner being capable of preventing the generation of clinkers and increasing combustion efficiency. The separated combustion burner for preventing clinkers, according to the present invention, has a body having a combustion chamber formed therein and combusts solid fuel, and comprises: a fuel supply part connected to the body so as to supply the solid fuel to the combustion chamber; a gas discharge pipe connected to the body so as to discharge combustion gas; a combustion partition wall for dividing a space of the combustion chamber into a first combustion space and a second combustion space; a first transfer part disposed in the first combustion space so as to transfer the solid fuel; a second transfer part disposed in the second combustion space so as to transfer the solid fuel; and a discharge part connected to the body so as to discharge ash formed after the solid fuel is combusted, wherein the first combustion space and the second combustion space communicate with each other, and the solid fuel can be supplied to the first combustion space.

Description

technical field [0001] The present invention relates to a separation burner for preventing slag, and more particularly, to a separation burner for preventing slag used in a heating boiler or the like. Background technique [0002] From industrial boilers to domestic boilers, there are various structures of boilers currently in use. Usually, the boiler is used as a heating unit for heating the indoor space comfortably and warmly in winter, early spring or late autumn when the temperature is low. The medium is heated, so that the heat medium such as heated water or steam circulates to the heating line to heat the indoor space. [0003] A variety of fuels can be used for combustion in the burner. Among them, biomass fuels such as pellets solidified with wood and the like are widely used because they are inexpensive and economical. [0004] However, biomass fuel contains various foreign substances such as silica, cellulose, lignin, and hemicellulose, so it may cause various pr...

Problems solved by technology

[0006] However, according to the conventional burner, heat is accumulated inside the combustion chamber, which is exposed to excessively high temperatures, and the fuel and foreign matter including sand and dust in the fuel are solidified by the high temperature, resulting in slag, etc.

Therefore, there are disadvantages in that fuel and dross are accumulated due to clogging of the moving passage of fuel and dross, which makes it difficult to carry out normal combustion, hinders the flow of air, degrades combustion performance, and is difficult to clean.

[0007] Also, since the space between the solid fuels is small, the air cannot be sufficiently supplied to the solid fuels stacked inside, so incomplete combustion occurs and the combustion efficiency and heating performance are reduced.

When the burner is a small burner, there is no serious problem because the amount of accumulated solids is small, but when a large amount of solid fuel is burned, the air cannot attack the solids accumulated in a large volume. The central part of the fuel, so only the outer side of the solid fuel pile is burned, so there is a problem that it is difficult to apply to a large-capacity burner

[0008] In addition, when a large amount of fuel is burned and thermally deposited, the combustion chamber made of metal, etc. is exposed to excessively high temperature, so that the device is corroded and damaged, resulting in a problem of reduced durability.

[0009] In addition, a large amount of dross accumulated inside the combustion chamber aggregates or deposits, and foreign matter such as dust and sand cannot be discharged due to accumulation, so they are accumulated or discharged in an unburned state, thereby reducing the combustion rate. In this case, there is a problem that the performance of the burner is reduced or it cannot be operated
