Optimization operation monitoring method of heating furnace

Abstract

The invention relates to an optimization operation monitoring method of a heating furnace, mainly solving the problems of overlarge excess air system and difficulty in diagnosis of fault and operation efficiency of the heating furnace, caused by imperfection of the traditional operation monitoring method of the heating furnace. The optimization operation monitoring method is characterized by comprising the following steps of: (1) detecting the flow rate of a heated medium and the temperatures of the heated medium entering and exiting the furnace and calculating a temperature difference, and calculating effective heat; meanwhile, detecting the gas consumption amount of the heating furnace, calculating heat generated by natural gas combustion, calculating the positive balance furnace efficiency through a computer, and displaying the positive balance furnace efficiency on a screen; (2) controlling flame combustion through a gas adjusting valve according to the temperatures of the heated medium entering and exiting the furnace; (3) detecting the gas flow rate and the flue temperature, and automatically adjusting an air flue for air distribution; and (4) detecting the temperature of a furnace tube and setting a temperature alarm point. The method disclosed by the invention can be used for monitoring the whole operation process of the heating furnace, realizing automatic control and alarming while a fault happens, thereby realizing the purposes of combustion optimization, energy saving and consumption reduction of the heating furnace.

Description

technical field [0001] The invention relates to the field of optimization of a heating furnace automatic control system of an oil field gathering and transportation system, in particular to a method for monitoring the optimal operation of a heating furnace. Background technique [0002] Heating furnace plays an important role in oil field production. How to make the heating furnace more energy-saving, how to improve the efficiency of the heating furnace and reduce the damage of the heating furnace by adjusting the operating parameters are the problems that need to be solved in the production and operation of the oil field. These need to be solved through the heating furnace. Energy saving optimization system to complete. At present, the heating furnace does not have a complete monitoring system for optimal operation, which leads to the lack of a perfect monitoring method. Because the load is generally low, and there is no fine adjustment device for the air distribution, the ...
