Combustion chamber structure with variable furnace wall thickness along length direction

Abstract

The invention relates to a combustion chamber structure with variable furnace wall thickness along the length direction. The combustion chamber consists of a furnace wall, a machine side furnace end and a coke side furnace end, and is divided into a plurality of vertical flame paths by vertical flame path partition walls; the furnace wall is built by furnace wall bricks, and the vertical flame path partition walls are built by partition wall bricks; the furnace wall is divided into three parts from a machine side to a coke side, namely a machine side furnace end furnace wall, a main body furnace wall and a coke side furnace end furnace wall; the thickness of the main body furnace wall is reduced in the direction from the machine side to the coke side. The heat transfer effects of differentvertical flame paths are effectively adjusted by changing the thickness of the furnace wall of the combustion chamber along the length direction; and the heat transfer efficiency is improved at the thinner part of the furnace wall, so that the total required heating coal gas amount, the coking heat consumption, the vertical flame path temperature and the nitrogen oxide generation amount during the production of the coke oven are reduced, and the purposes of energy conservation, emission reduction and environmental protection are achieved on the aspect of source treatment.

Description

technical field [0001] The invention relates to a coke oven combustion chamber structure, in particular to a combustion chamber structure with variable furnace wall thickness along the long direction. Background technique [0002] In the coking industry, as a coking unit, the coke oven is characterized by high energy consumption per unit product, large exhaust gas emissions, and the generation of harmful gases such as nitrogen oxides. In view of the urgent requirements of energy saving, emission reduction and environmental protection, the structure of the coke oven is also continuously improved, such as the use of exhaust gas circulation, multi-stage heating and other methods. [0003] In the traditional combustion chamber structure, the thickness of the furnace wall is uniform along the machine side-coke side, that is, the length of the combustion chamber, and this structure is relatively simple. However, in order to reduce the coke push resistance and facilitate coke push...
