Annealing method of gas furnace

Abstract

The invention discloses an annealing method of a gas furnace, and relates to the improvement of the annealing method of the gas furnace in the metallurgy and coal chemical industry. The annealing method of the gas furnace is characterized in that a control valve is added on a saturated pipe on the surface of the gas furnace to control the feed of a gasifying agent. According to the annealing method of the gas furnace, the control valve is mounted on an air saturated pipe of the furnace to serve as an air regulating valve in the annealing period, is opposite to an ash discharge door, and can regulate the air volume to the minimum in the annealing process and decelerate the gasifying speed; the gasifying agent passes through the saturated pipe to uniformly distribute air and ensure the stability of the furnace; and the inside of an annealing valve just faces a water jacket to generate a layer for mixing steam and air, so as to synchronously regulate the temperature inside the furnace and steam amount automatically, achieve the effect of mild annealing and effectively prevent material layers from freezing in the annealing process. The control valve is at a proper position and is convenient and fast to operate. The condition of fire beds inside the furnace is detected at a specific temperature to prolong the annealing time safely and reduce the unnecessary operation consumption.

Description

technical field [0001] The invention relates to an annealing method of a gas generator, which relates to an improvement of an annealing operation method of a gas generator in a metallurgical coal chemical process. Background technique [0002] Producer annealing is a non-production state in which the gas producer is isolated from the system and keeps the material bed unextinguished. It is a common production method adopted during production adjustment and maintenance. At present, the TG3M-I generator adopts the natural ventilation method of opening the lower ash door. Although it ensures that the material layer does not extinguish the fire, it also has many shortcomings: after opening the lower ash door, the material layer sucks pure air, and the cloth The uneven wind causes the temperature of the fire layer to rise continuously, and the coal consumption decreases slowly. If the furnace is simmering for 3-5 days, it needs to be blown to add coal once, which will increase...
