Abstract

The invention discloses an emergency chain control method of heating furnace dangerous condition, device and system. The control method comprises the steps that the temperature and smoke composition in a flue of a heating furnace and the pressure difference of inner flowing fluid in a plurality of pipelines passing through the heating furnace are detected; the temperature is compared with the setting temperature, and if the temperature is greater than or equal to the setting temperature, a first judgment condition is obtained; the size of the flue gas component is compared with the size of a preset flue gas component, and if the flue gas component is greater than or equal to the preset flue gas component, a second judgment condition is obtained; the pressure difference is compared with a preset pressure difference, and if the pressure difference is greater than or equal to the preset pressure difference, a third judgment condition is obtained; and if two judgement conditions of the first judgment condition, the second judgment condition and the third judgment condition are met at the same time, the heating furnace is controlled to stop heating, the flow fluid in the pipelines is cut off, and a lazy gas source connected to the heating furnace is opened.

Description

technical field [0001] The invention relates to the field of heating furnaces in oil fields, in particular to an emergency chain control method, device and system for dangerous situations of heating furnaces. Background technique [0002] The heating furnace in the station of the natural gas branch company is a medium and large fire tube heating furnace, which has high efficiency, large processing capacity, and can raise the temperature to a high level, playing an important role in the station. But its disadvantage is that the burner directly heats the coil, the medium in the coil is pure crude oil, and the production temperature needs to be high, generally around 200°C. Once the crude oil leaks in the coil, it will cause a fire and may cause a major safety production hazard of deflagration and explosion. ACCIDENT. Therefore, there is an urgent need for a set of emergency treatment devices for dangerous situations, which can promptly and effectively extinguish the fire and ...
