Shandong ductile iron pipe company since 2005, environmental protection and recycling energy from the point of view, the establishment of two sets of Blast Furnace Gas Steam Turbine blower system, Blast Furnace Gas Turbine blower steam boiler combustion control system is divided into systems, steam blower control system and the boiler furnace safety supervisory system consists of three parts.As we all know, is a state boiler pressure vessel strict inspection, the important parameters of the test and control relationship between the existence of strict interlock control, detection and control occur if the disorder, the light shutdown, affecting production, resulting in waste of manpower and energy, re-who will lead the boiler explosion, especially in steam boilers, direct casualties, equipment damage and other irreversible losses. Steam turbine power output as a blower unit, the pressure for the stability of blast furnace combustion air delivery is necessary to ensure high stability of blast furnace conditions, so if not properly controlled, the light is not suitable for causing combustion air, affecting the blast furnace production, serious cases can cause steam turbine blower hard fault of their own equipment, seriously affecting the orderly production and waste of corporate funds. Since the continuity of blast furnace production requirements, the combustion air supply is also the presence of the corresponding continuity requirements, in addition to the annual boiler inspection system, the basic run throughout the year, which requires the automatic control system design and equipment selection have high reliability and emergency response requirements. Production process, the presence of toxic gases and explosion factors, will require the automatic control system design and equipment selection on the appropriate preventive measures.Conventional boiler, steam turbine run through a variety of analog and indicators to monitor its operation, in order to ensure that equipment operating within the safe operation, including a number of boiler temperature, pressure, water level, the valve opening, flow data monitoring, steam turbine speed, oil level, temperature, pressure and flow monitoring data. As the computer continues to develop, control theory and control equipment increasingly updated to the 1980s, the boiler control system, steam turbine control system to the progressive realization of a micro-computer as the core of the PLC or DCS control system to replace the use of electrical instrumentation as based automation control system, boiler and steam turbine blower centralized monitoring of the parameters, while the PC-based host computer and operating needs through the process required to display a variety of parameters and curves, making it more intuitive to more accurately reflect the dynamic changes in equipment operation.
