General operation principles of central control room:
The general operation principle of the new dry process kiln system is to timely adjust the parameters of each process system according to the changes of the external conditions of the plant, so as to keep the "balanced and stable" operation of the system to a large extent, and continuously improve the operation rate of the equipment.
"Equilibrium and stability" is a relatively static state in the development process of things, which is conditional and temporary. In the actual production process, due to the changes and interference of various subjective and objective factors, it is inevitable to break the original equilibrium and stable state, which requires the operator to make appropriate adjustment to restore or reach the new equilibrium and stable state under new conditions. Therefore, it is the main task of the control room operator to use various adjustment means to maintain or restore the production equilibrium and stability.
As far as the production of the whole plant is concerned, the operation of other sub item systems should be adjusted to ensure the balanced and stable production of the sintering system. In terms of the sintering system itself, it is necessary to maintain an optimized and reasonable calcination system, strive to give full play to the calcination capacity of the kiln, adjust various parameters timely according to the conditions of raw materials, fuels and equipment, and greatly improve the operation rate of the kiln on the premise of ensuring the quality of clinker.
In the specific operation of the central control room, the 12 word formula of "grasping both ends, ensuring key points, seeking stability, and creating all-round excellence" was adhered to. The so-called "two ends" is to focus on the two major links of kiln tail preheater system and kiln head clinker burning, taking into account before and after, and coordinated operation; the so-called "key point" is to ensure the safe and normal operation of coal feeding and feeding equipment of the system, and create conditions for the "dynamic balance" of clinker combustion; the so-called "stability" means that in the process of parameter adjustment, the proper amount of coal can be timely and appropriately, Small and gradual adjustment, timely adjustment to overcome large fluctuations, to maintain the basic stability of the thermal system. The so-called "all-round optimization" is to sum up the system operation parameters suitable for the actual plant through a period of operation, careful summary, combined with field thermal calibration and other testing work, namely, optimization parameters, so as to make the kiln operation larger and achieve outstanding, high-yield, low consumption, long-term safe, stable and civilized production.
