ABSTRACT
Fuel boilers with urban development, more and more widely. Due to its previous use coal boiler burning in the amount of carbon dioxide emissions and dust pollution of the environment and be washed out gradually, and the corresponding with fuel boilers instead of coal-fired boilers has been widely used in hotels, shopping, etc. Boiler is one-time energy coal oil and gas quantity of steam secondary energy converts the important power equipment. According to the statistics, China has all kinds of industrial boiler about 25 million sets. The yield of coal consumption year 1/3, also consume large amounts of oil and gas.
By PLC control oil boiler control system is applicable to various kinds of imported and domestic fuel burner for boiler. implement automatic control, including the boiler water and steam pressure, the parameters of the system test, instructions, alarm, adjusting control, etc. The design of the first identify the fuel boilers control object and control based on object control design of the overall structure and oil burning boiler operation, and design of hardware and software systems in the system, the hardware circuit of design, and the auxiliary circuit in the software design of each module in the design and debug, namely the start and stop, abnormal condition of automatic fire and water level control.
