The present invention relates to a combustion chamber for fine fuel combustion. More particularly, the present invention relates to a combustion chamber for fine fuel combustion that improves combustion efficiency of finely divided fuel.

Oil prices have soared in recent years, suggesting that the global energy crisis is spreading. This is because the alternative sources of petroleum are insufficient and the majority of industries depend on oil. Coal, which was the main fuel before the development of petroleum, has the disadvantages of low calorific value, long ignition time and inconvenience in transportation compared to petroleum, and it is currently being treated as an energy source used only for limited use such as industrial power plants .

As shown in FIG. 1, it is preferable that the upper side of the combustion chamber housing 100 extends toward the side. The cyclone 120 is positioned below the combustion chamber housing 100 and is configured to collect ash generated after combustion of the fine fuel. The ash is configured in a conical shape and the ashes are collected at the center of the cyclone 120, the lower portion of the cyclone 120 is provided with a reprocessing apparatus (300). The hollow portion of the combustion chamber housing 100 serves as a combustion chamber in which fine fuel is combusted, and may be a primary combustion chamber or a secondary combustion chamber according to a design. 1 and 2, the hollow portion of the combustion chamber housing 100 serves as a secondary combustion chamber.

Next, the combustion tube 210 is a pipe-shaped configuration that is provided inside the combustion chamber housing 100 to provide a space where the fine fuel is combusted, the inlet 202 through which the fine fuel is introduced, and the combustion tube at the other end thereof. At 210 the outlets 204a, 204b, 204c are provided which discharge the flame ignited and combusted and some unburned fine fuel. Only one outlet 204a may be provided at the other end of the combustion tube 210, but as shown in FIG. 1B, when the additional discharge ports 204b and 204c extend in various directions, the combustion tube ( Emission of fuel and flame combusted from 210 may be facilitated to increase combustion efficiency. For example, when the discharge port 204a is formed from the left side to the lower side as shown in FIG. 1B, the discharge port 204c formed from the right side of the combustion tube 210 toward the lower side, and the discharge hole formed toward the upper side from the left side of the combustion tube 210. Most preferably, 204b is further formed.

In addition, the combustion tube 210 according to the first exemplary embodiment of the present invention includes a first bent part 212 and a second bent part 214. The overall shape of the combustion tube 210 is a continuous shape of the letter 'W (double oil)' to 'S (S)'. The first bent part 212 and the second bent part 214 are bent in opposite directions to each other, the cross-sectional shape (Fig. 1 (b)) of the two bent parts (212, 214) is approximately a semi-circular shape desirable. Although not shown, a straight portion (not shown) extending in the horizontal direction may be provided between the first curved portion 212 and the second curved portion 214. For example, when the elliptic shape of the combustion chamber housing 100 shown in FIG. 1A becomes a longer ellipse, the radius of curvature of the bends 212 and 214 is increased or the above-described straight portion ( By not adding), the combustion unit 210 can be efficiently installed in the combustion chamber housing 100.

When fine fuel is injected into the combustion tube 210 preheated to the ignition temperature of the pulverized coal, for example, by blowing air, the fine fuel is injected into the inlet 202 of the combustion tube 210 and the first bent part 212 located above. Combustion starts. At this time, the fine fuel strikes the first bent portion 212 and further increases the time to stay in the combustion tube 210, and ignition for ignition may be additionally generated. After that, the fine fuel continues to be burned while moving along the combustion tube 210, and the flame and the high temperature heat generated by the combustion also move along the combustion tube 210. The flame and heat discharged through the outlet 204 of the combustion tube 210 and some unburned fine fuel are combusted secondary in the combustion chamber housing 100. The combustion chamber housing 100 is also heated by the heated combustion tube 210, and even in the hollow portion of the combustion chamber housing, the fine fuel continues to be burned and the flame and heat continue to move upwards of the combustion chamber housing 100. . Ash generated in the combustion process is discharged to the outside by the ash treatment device 300 after falling on the cyclone (120).
