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. How to Leak Detection of Vacuum Furnace 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.304 stainless steel cold rolling and vacuum annealing process 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.How to control distortion in vacuum heat treatment of sheet parts?
