Energy conservation method of monotube boiler based on automatic control system

Abstract

The present invention discloses an energy conservation method of a monotube boiler based on an automatic control system. The method comprises the following steps: the step 1: performing real-time communication, timely obtaining related data of a boiler unit and the boiler operation condition, collecting data and performing analysis, and feeding back information to the system; and the step 2: in the boiler operation process, realizing data information transmission of the system, calculating an optimal value, and performing control operation. The energy conservation method of the monotube boiler based on the automatic control system allow the modern technology to be fused to break the disadvantages of the operation of a traditional monotube boiler, reduce the environmental pollution, save the energy consumption and improve the production efficiency and quality.

Description

technical field [0001] The invention relates to an energy-saving method for a once-through boiler, in particular to an energy-saving method for a once-through boiler based on an automatic control system, and belongs to the field of environmental protection and energy conservation. Background technique [0002] Once-through boilers appeared at the beginning of the 20th century, and many foreign countries regard them as the main form of large-scale power plant boilers. Once-through boilers mainly refer to boilers that use the pressure of water pumps as the power basis and convert them into superheated steam through economizers, superheaters and other parts. , in comparison, since the once-through boiler has no natural circulation boiler drum, the amount of metal can be saved in the manufacturing process, and the layout of the water wall is relatively free, which can break through the limitation of water circulation and respond flexibly. It is favored by the industry and has bee...

[0002] Once-through boilers appeared at the beginning of the 20th century, and many foreign countries regard them as the main form of large-scale power plant boilers. Once-through boilers mainly refer to boilers that use the pressure of water pumps as the power basis and convert them into superheated steam through economizers, superheaters and other parts. , in comparison, since the once-through boiler has no natural circulation boiler drum, the amount of metal can be saved in the manufacturing process, and the layout of the water wall is relatively free, which can break through the limitation of water circulation and respond flexibly. It is favored by the industry and has been widely promoted. and popularization; however, due to the high energy consumption and serious environmental pollution during the operation of the traditional once-through boiler; therefore, in order to effectively improve the operation effectiveness of the once-through boiler and achieve the daily standard of energy-saving and environmentally friendly operation, it is necessary to strengthen its improvement and perfection It is particularly important; the manufacture of energy-saving and environmentally-friendly boilers can not only avoid environmental pollution, but also pay more attention to energy conservation and environmental protection, helping production companies control costs, optimize resource allocation, and improve economic benefits
