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 Process of Machine Tool Spindle 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.Different Quenching and Tempering of GCr15 Bearing Steel Balls 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.Vacuum brazing of elliptical corrugated horn
