Through research, we found that the control method of industrial boilers in my country is a single-point multi-step control method, and multiple single settings must be made for the control of each device. There are many auxiliary devices for the boiler system. For example, the boiler operating status When fluctuations occur, the operation steps, parameter modification, recovery and other work are more cumbersome, and the operation accuracy will be affected

[0033] (1) On-site inspection of the boiler to confirm that the mechanical and electrical equipment is in good condition, normal, and the environment is safe to start, and the boiler ignition equipment module is turned on. The control system self-diagnoses according to the initial self-inspection procedure, and scans and confirms the failure status of communication and electrical equipment. No glitches. The boiler liquid level detection determines that the liquid level is in the process safety height range.
[0034] (2) Start the boiler ignition module, start the grate motor step by step, start the coal lowering motor, let the coal laying grate run forward for 1.5-2.0 meters, start the induced draft fan at a low speed, and slowly ignite the coal to make the temperature reach set value.
[0035] (3) Start the booster module, the grate speed will increase, the speed of the induced draft fan will increase, the temperature of the furnace will rise, and the water in the pot will e...

The invention relates to a modularized control method of boiler which is mainly used for finishing modularized control of boiler ignition preparation, ignition to start the boiler, boiler running, boiler stopping, and overhauling process; the method is applicable to boiler equipment. The modularized control method of boiler divides the boiler into 12 modules by different using periods or safety protecting measures: a boiler ignition preparation module, a boiler ignition module, a boiler boosting module, a boiler adjusting module, a boiler tuning module, a boiler sewage discharging module, a boiler pressure relief module, a boiler stopping module, a boiler fault module, a boiler warning module, a boiler overhauling module, and a boiler linkage simulation module; control scheme of each module is enacted to finish the cooperation of each physical equipment; and the former scrappy operation manner of finding corresponding equipment according to the equipment overview map of individually setting a certain parameter is changed into the manner of invoking relative parameters in batches from the constituent subsystems of the boiler; the relative factors thereof are configured in advance in the automatic mode, whereas the factors are independent from each other in the manual mode, thereby achieving the safe, stable, quickly responded modularized operation of the boiler.
Description
technical field [0001] The invention relates to a boiler modular control method, in particular to a control method for boiler safety, startup, operation, unloading, shutdown and other links. The utility model belongs to the technical field of power boiler equipment and control. Background technique [0002] Steam boilers, as steam production equipment for heat and power sources, play an important role in the national production and living economy, and are widely used in various sectors of the national economy. In order for a boiler to operate safely, reliably and effectively, and the operating parameters reach the design value, in addition to the boiler itself and various auxiliary equipment in good condition, it must also require that the automatic instrumentation work and the automatic control system scheme be correct. Through research, we found that the control method of industrial boilers in my country is a single-point multi-step control method, and multiple single set...
