Three-in-one boiler provided with automatic boiler control system

Abstract

The invention creatively relates to a three-in-one boiler provided with an automatic boiler control system. The three-in-one boiler comprises a steam boiler body, an organic heat carrier convection heat exchanger, a hot air heat exchanger and the automatic boiler control system used for controlling the steam boiler body, the organic heat carrier convection heat exchanger and the hot air heat exchanger to be operated. According to the three-in-one boiler provided with the automatic boiler control system, a three-in-one boiler structure provided with the automatic boiler control system is creatively adopted, the purpose that the three heat transfer environments of the radial heating surface region, the high-temperature convection region and the low-temperature convection region are separately arranged in the boiler is achieved, meanwhile on the dependence of radiation and convection heat exchange of the three kinds of heat media of steam, heat conductance oil and smoke, three types of heat energy are output, so that the overall heat transfer efficiency of the boiler can be improved, and the secondary heat loss is reduced; and meanwhile the whole boiler control system is divided into an upper industrial personal computer, a programmable logic controller, a data acquisition unit and an action execution unit by the adoption of the centralized control distribution driving idea, so that automatic control over the three-in-one boiler is achieved.

Description

technical field [0001] The invention relates to a boiler, in particular to a three-in-one boiler equipped with an automatic boiler control system. Background technique [0002] As an important power equipment in industrial production and central heating process, boiler plays a vital role in people's production and life. Existing circulating fluidized bed boilers usually can only use the heat generated by boiler combustion once and in a single form. The form of heat conduction is single, and it is impossible to effectively control the thermal efficiency by controlling the various frequency conversion factors in the boiler, resulting in the operation of the entire boiler.

Problems solved by technology

Existing circulating fluidized bed boilers usually can only use the heat generated by boiler combustion once and in a single form. The form of heat conduction is single, and it is impossible to effectively control the thermal efficiency by controlling the various frequency conversion factors in the boiler, resulting in the operation of the entire boiler. The heat conduction energy loss in the process is serious, and the thermal efficiency and utilization rate are low

[0003] At the same time, boilers inevitably face the trend of large-scale and large-scale changes in the process of development, and in this process, the problems of diversified heat transfer media, heat transfer environments and heat transfer forms are too high and difficult to effectively control.

Traditional circulating fluidized bed boilers are usually only set as a heat transfer medium in a single heating environment for one form of heat conduction, resulting in poor adaptability of the boiler and low industrial utilization; moreover, the increase in boiler scale and volume at the same time leads to During the operation of the boiler, the number of influencing factors is increasing, and the situation is complex and changeable. The traditional method of relying on manual experience control has serious hysteresis and low efficiency, and cannot automatically and effectively deal with and optimize various situations that occur during the operation of the boiler in a timely manner.
