Problems solved by technology

However, the visual infrared temperature measuring device can only measure the surface temperature of the furnace tube, which is not a very good choice for monitoring the reaction temperature of the burnt inside the furnace tube.
In addition, the uniformity of temperature and the flame condition in the furnace are also very important factors in the process of adjusting the temperature, and the single visual infrared temperature measuring device cannot observe the flame condition

Abstract

The invention relates to a scorching process monitoring system for an ethylene cracking furnace. The scorching process monitoring system is composed of a visual multi-spectral furnace temperature field monitoring device installed at a cracking furnace radiant section, a multi-parameter gas monitoring device installed at the tail of a furnace tube, and a furnace tube outlet temperature monitoring device installed at the furnace tube outlet. Therefore, the working condition of the ethylene cracking furnace can be detected timely and accurately; and the basic basis is provided for controlling thework condition.

Description

technical field [0001] The invention belongs to the field of petrochemical industry, in particular to a method and device for monitoring and controlling the burning process of an ethylene cracking furnace. Background technique [0002] Ethylene is an important chemical raw material, and one of the petrochemical products with the largest demand and production volume, and it also marks the development level of a country's petrochemical industry. The tube cracking furnace is the main device for producing ethylene. Hydrocarbons will form coke on the inner wall of the furnace tube while the steam cracking reaction occurs in the radiant section of the cracking furnace. The thermal resistance of coke is large, and at the same time, it will cause the pressure drop of the fluid in the pipe to increase. When the cracking furnace has been in operation for a period of time, due to coking, the temperature of the outer wall of the furnace tube in the radiant section or the outlet temper...
