Technical Field
The invention relates to the technical field of coke ovens, in particular to a lamp cap brick which is arranged in a vertical flame path and is provided with a plurality of sections of outlets.
Background
The coke oven consists of heat accumulating chamber, inclined passage, combustor, carbonizing chamber, furnace top, etc. The coal gas and air are mixed and combusted in the combustion chamber, and heat is transferred to the coal in the carbonization chamber in a heat conduction and heat radiation mode, so that the coal is converted into coke. The thermal system of the coke oven comprises the adjustment of the long-direction heating temperature and the high-direction heating temperature, and the uniform distribution of the temperature of the oven wall of the carbonization chamber can save fuel and prevent the damage of the oven body of the coke oven due to local overheating. At present, the large-scale coke oven adopts modes of waste gas circulation, multistage heating, high-low lamp cap setting and the like to adjust the high-directional heating uniformity of the coke oven.
The coke oven gas outlet pipe brick at the bottom of the vertical flame path is called a lamp cap brick (or burner block). The function of the lamp cap brick is to ensure reasonable combustion of the coke oven gas when the coke oven gas is used for heating, so that the coke cake is heated uniformly in a high direction. In general, the top surface of the burner tile is flush with or slightly higher than the bottom surface of the riser, referred to as a low burner, and the top surface of the burner tile is higher than the exhaust gas circulation holes, referred to as a high burner. The high-low lamp cap is to set the outlets of the heating gas in two adjacent vertical flame paths in the combustion chamber at different heights from the bottom of the carbonization chamber, so that the heating condition of the upper part and the lower part of the combustion chamber can be slightly improved.

In order to achieve the above purpose, the invention is realized by adopting the following technical scheme:
A lamp cap brick with multi-section outlets is arranged at the bottom of a vertical flame path, a gas inlet is arranged at the bottom of the lamp cap brick and is connected with a gas path on the gas pipe brick in a chute area, at least 2 gas outlets are arranged at the top of the lamp cap brick, and the heights of the gas outlets are different.
The sectional areas of the gas outlets are the same or different.
The cross section of each gas outlet is circular, elliptical or polygonal.
The gas outlets are vertically upwards arranged, and the height of the lowest gas outlet is higher than the height of the upper edge of the waste gas circulation hole.
And each gas outlet is provided with an adjusting brick or a plug brick.
Compared with the prior art, the invention has the beneficial effects that:
