Combustion chamber burner structure with heating system and operation method

Abstract

The invention discloses a combustion chamber burner structure with a heating system and an operation method. The heating system is arranged on the machine side and / or the coke side of a coke oven combustion chamber, the heating system comprises a metal hollow plate, the metal hollow plate is arranged between inner-layer refractory bricks and outer-layer refractory bricks of a burner brickwork, theside, which is connected with the inner-layer refractory bricks, of the metal hollow plate is the same as the inner sides of the outer-layer refractory bricks, the side, which is connected with the outer-layer refractory bricks, of the metal hollow plate is the same as the outer sides of the inner-layer refractory bricks, a smoke inlet and a smoke outlet are formed below the metal hollow plate, the smoke inlet is connected with a chute below a middle vertical flame path through a smoke pipeline, and the smoke outlet is connected with a chute below the burner vertical flame path. The problem of low temperature of the vertical flame path of the combustion chamber burner of the coke oven is solved, and the coke quality of the burner is improved. The process is simple and convenient to operate and easy to implement, and resources are saved. The temperature of the coke cake in a carbonization chamber of the burner of the coke oven can be increased to 950-1050 DEG C, and the strength of thecoke after reaction is increased to 68.1% from 66.3%.

Description

technical field [0001] The invention belongs to the field of coking, and relates to a technology for increasing the temperature of a burner head of a coke oven combustion chamber, in particular to a structure and an operation method of a burner head of a combustion chamber with a heating system. Background technique [0002] At present, the coke oven combustion chambers of coking plants of most domestic iron and steel complexes use blast furnace gas and air to preheat and burn, and transfer the heat to the carbonization chamber through the partition wall for high-temperature carbonization of pulverized coal. Because there are few combustible components in the blast furnace gas, the calorific value is low, and the heat dissipation of the combustion chamber burner vertical flue is large, resulting in low temperature of the combustion chamber burner vertical flue. During the coking time, the coke at the furnace head of the carbonization chamber is not fully mature, resulting in...

Problems solved by technology

[0007] Aiming at the problems of high heat dissipation and low temperature in the furnace head of the coke oven combustion chamber, and the decrease of coke strength at the furnace head of the carbonization chamber, the present invention proposes a structure and operation method of the furnace head of the combustion chamber with a heating system. The high-temperature flue gas discharged from the fire channel supplements the furnace vertical fire channel. This process is simple to operate and easy to realize. It can quantitatively adjust the temperature at the furnace vertical fire channel, improve the quality of coke at the furnace head, save resources and reduce coking costs.
