    一、英文原文： Boiler computer control Boiler computer control： The boiler micro computer control, is a new technology which the recent years developed, it was the microcomputer soft, the hardware, the automatic control, the boiler energy conservation and soon several technical in close integration with product, our country existing center, small boiler more than 300,000, the coal consumption accounted for our country raw coal output every year 1/3, at present the majority industry boiler still was at the energy consumption to be high, to waste, the environmental pollution in a big way and so on the serious production condition. Enhances the thermal efficiency, reduces the coal consumption, carries on the control with the microcomputer is has the profound significance the work. As the boiler control device, its primary mission is guaranteed the boiler the security, is stable, the economical movement, reduces operator's labor intensity. Uses the micro computer control, can carry on the process to the boiler the automatic detection, the automatic control and so on many functions. The boiler microcomputer control system, generally is composed by the below several parts, namely by the boiler main body, a measuring appliance, the microcomputer, the hand automatic cut over operation, the implementing agency and the valve, the slippery difference electrical machinery and so on partially is composed, a measuring appliance the boiler temperature, the pressure, the current capacity, the oxygen quantity, the rotational speed isometric transforms the voltage, the electric current and so on sends in the microcomputer, the hand automatic cut over operation part, manual when by the operator hand control, controls the slippery difference electrical machinery and the valve with the manipulator and so on, is automatic when sends out the control signal to the microcomputer partially to carry on the automatic operation after the execution. The microcomputer carries on the monitor to the entire boiler movement, reports to the police, the control guaranteed the boiler is normal, reliably moves, except for this for guaranteed the boiler movement these curity, when carries on the microcomputer system design, to the boiler water level, the boiler dome pressure and so on the important parameter should establish the conventional measuring appliance and the alarm device, guaranteed the water level and the dome pressure have the dual even tertiary alarm device, this is essential, in order to avoid the boiler has the significant accident. Control system: The boiler is a more complex controlled member, it not only adjustment quantity many, moreover between various types and quantities mutually relates, mutually affects, mutually restricts, boiler interior energy conversion mechanism quite complex, therefore must establish a more ideal mathematical model to the boiler quite to be difficult. Therefore, has made the boiler system simplification processing, decomposes is three relatively independent governing systems. Certainly also may subdivide other system like amount of wind control loops in certain systems,
