Embodiment Construction

[0017] See figure 2 , a petroleum liquefied gas oven and its start-up method, comprising oven main pipeline 1, branch pipe 2, cock 3, burner 4, the oven main pipeline 1 is arranged in the flue corridor below the operating platform 6 on both sides of the machine and coke 7. The branch pipe 2 rises to the operation platform 6 on both sides of the machine and coke along the gap between the steel columns, and connects with the burner 4 installed in the furnace door oven hole on the side of the machine and coke; There are cocks 3.

[0018] See image 3 , the burner used in the oven is a specially designed burner, including a burner inner tube 11, a burner outer tube 9, a gas nozzle 8, an air conditioner 10, and a gas nozzle 8 is installed on the head of the burner inner tube 11. An air conditioner 10 is installed on the mouth outer pipe 9 . When the coke oven is baked, the burner is installed in the oven hole at the lower part of the furnace door on the machine and coke side. ...

Abstract

The invention relates to a method for drying a furnace and staring operation with liquefied petroleum gas, which uses liquefied petroleum gas to dry a furnace. The final temperature of drying furnace is 950-1000 DEG C. Arranged drying furnace pipelines comprise a drying furnace main pipeline, branch pipes, valvecocks and combustion nozzles, wherein the drying furnace main pipeline is arranged in a flue aisle below operation walking-platforms of machine and coke sides; the branch pipes extend upon the operation walking-platforms of the machine and coke sides along the clearance between steel posts and connected with the combustion nozzles in drying furnace holes on furnace doors at the machine and coke sides; and the branch pipes are provided with the vlavecocks. The invention can effectively solve the problem that liquefied petroleum gas is pyrolyzed in a brick flue to generate graphitic carbon resulting in blockage.

Description

technical field [0001] The invention relates to the technical field of coking, and is applicable to a method for drying and starting a new coke oven by using liquefied petroleum gas after completion of masonry and installation. Background technique [0002] After the coke oven masonry is completed, it must go through the oven and start-up process before it can enter the production state. The oven is the transition process of the coke oven body from a cold state to a hot state. [0003] The traditional coke oven oven method uses coke oven gas as the oven fuel, see figure 1 The oven main pipe 1' is arranged on the machine and coke operating platform 6' on the second floor, and the gas burner 4' connected with the oven gas branch pipe 2' extends into the carbonization chamber through the oven hole provided at the lower part of the oven door to burn and burn. Furnace required heat, gas volume is regulated by cock 3'. The coke oven starts to heat up from normal temperature, an...
