Thermal power generation boiler intelligent combustion optimizing system and realizing method thereof

Abstract

The invention aims to provide a thermal power generation boiler intelligent combustion optimizing system and a realizing method thereof, belonging to the relevant technical fields of energy sources, environmental protection, software information, and the like. The system mainly comprises a human-computer interface module and an intelligent algorithm subsystem, wherein a boiler operator can configure relevant parameters of coal species, and the like by the human-computer interface module, and the human-computer interface module can provide an optimized target for the whole system and clearly display an optimized model predicted by the system; and the intelligent algorithm subsystem generates a combustion optimizing model under the guide of the human-computer interface module according to information provided by a distributed control system (DCS) and an environmental pollutant monitoring module. The invention can provide the boiler performance optimized real-time online analyzing function for a front-line staff of a power plant, analyze the optimized parameter and the optimized target of a boiler system by the system and provide a concrete performance optimizing measure and a technical guide.

Description

technical field [0001] The invention belongs to the technical fields of energy, environmental protection, software information and the like. Background technique [0002] my country is a major coal-producing and coal-burning country in the world. The acid rain caused by sulfur dioxide and nitrogen dioxide emitted by coal-burning has affected 40% of the country's area of ​​nearly 4 million square kilometers. Power plants account for more than 60% of pollutant emissions. Environmental protection The problem is imminent; on the other hand, there is a big gap between my country’s thermal power coal consumption and foreign advanced levels. In 2005, the national average power supply coal consumption of China’s electric power industry was 374g / kWh, Japan’s Tokyo Electric Power Co. The company's coal consumption for power supply in 1999 was 332.1g / kwh. At present, most domestic small units with large emissions and high energy consumption are facing the situation of shutdown and elimi...

Problems solved by technology

At present, most domestic small units with large emissions and high energy consumption are facing the situation of shutdown and elimination

[0003] Among the existing optimization methods of coal types, some can improve the thermal efficiency of combustion, but increase the discharge of pollutants and aggravate environmental pollution; some focus on reducing environmental pollution while ignoring the thermal efficiency of boiler combustion
