Embodiment
[0078] In this case, the process flow diagram of a waste incineration power plant in a waste incineration power plant is as follows figure 2 As shown, waste heat utilization technology is not used in this process.
[0079] The entire waste incineration power plant is divided into two parts: a waste incineration system and a thermal power generation system. The waste incineration system includes an incineration-waste heat boiler and necessary supporting equipment not shown in the figure, such as a three-stage desuperheater and various heating surfaces (such as Evaporators, superheaters, economizers, water walls, etc.), while thermal power generation systems include steam turbines, condensers, generators, condensate pumps, low-pressure heaters, deaerators, and feed pumps. The waste-to-energy process is as follows: the solid waste to be treated, primary air and secondary air all enter the incineration-waste heat boiler, so that the solid waste is converted into heat energy throu...

The invention discloses a process optimization method and device for a waste power plant based on quantitative characterization of comprehensive performance. The invention provides a method for optimizing a waste power plant based on the quantitative characterization of comprehensive performance. The method can analyze the energy conversion link of the waste incineration power generation process according to the quantitative characterization coefficient of the comprehensive performance. Starting from the overall unit of the waste incineration energy system, it does not Individual components are emphasized. According to the process flow of selecting different optimization technologies, the energy efficiency of the waste incineration plant is analyzed from a macro perspective, and the best solution with the highest energy efficiency improvement can be selected from different energy efficiency improvement optimization solutions. Guidance on how to improve the energy utilization rate of units in waste-to-energy plants.
Description
technical field [0001] The invention relates to the technical field of energy efficiency analysis, in particular to process optimization of a waste incineration power plant. Background technique [0002] Garbage is the solid waste generated in people's daily life or activities that provide services for daily life. With the increase of garbage production and the improvement of public awareness of environmental protection, incineration has become the main way of garbage disposal in my country. Compared with other treatment methods, waste incineration is guided by the development of circular economy, which can reduce waste volume by more than 85% to 90%, and can also use waste heat for power generation and heating, so it is a mainstream development direction. [0003] With the continuous development of technologies such as waste heat reuse and thermal energy cascade utilization, existing waste-to-energy power plants often have room for transformation to improve thermal energy u...
