PLC Control of Industrial Boiler The boiler is one of the important equipments in power plants and other industrial enterprises. Its function is to convert the energy stored in the fuel into heat energy through combustion, and transport it to various equipment in the form of steam or hot water. At present, most of the industrial boilers in our country are controlled manually, or are regulated by a simple instrument and a single-loop system, which wastes a lot of fuel. Vacuum Heat Treatment of Cr12MoV Steel Ceramic Die As a whole, the industrial boiler has many controlled and controlled variables and many disturbance factors, and there is obviously a complex relationship between many parameters. For the complex system of industrial boiler, because the internal energy conversion principle is too complicated, it is difficult to achieve the ideal control effect by conventional control in the past. Therefore, the intelligent control method can obtain better control effect.Analysis of Defects in Vacuum Brazing of Aviation Aluminum Alloy Chassis As an important power equipment, the task of the boiler is to supply qualified steam and make the boiler evaporation meet the requirements. For this reason, the main parameters of the production process must be strictly controlled. Boiler equipment is also a complex control object. The main input variables are load, boiler feed water, fuel amount, desuperheating water, supply air and induced air, etc. The main output variables are drum water level, steam pressure, superheated steam temperature, furnace negative pressure, excess Air, flue gas oxygen content, etc.Analysis of Defects in Vacuum Brazing of Aviation Aluminum Alloy Chassis These variables are related to each other. For example, changes in steam load will inevitably cause changes in drum water level, steam pressure and superheated steam temperature. Therefore, boiler equipment is a multi-input, multi-output and interrelated control object.
