Application of Multivariate Reinforcement Learning Engine in Optimizing the Power Generation Process of Domestic Waste Incineration

Garbage incineration is an ideal method for the harmless and resource-oriented treatment of urban domestic waste.However,current domestic waste incineration power plants often face challenges related to maintaining consistent steam production and high operational costs.This article capitalizes on the technical advantages of big data artificial intelligence,optimizing the power generation process of domestic waste incineration as the entry point,and adopts four main engine modules of Alibaba Cloud reinforcement learning algorithm engine,operating parameter prediction engine,anomaly recognition engine,and video visual recognition algorithm engine.The reinforcement learning algorithm extracts the operational parameters of each incinerator to obtain a control benchmark.Through the operating parameter prediction algorithm,prediction models for drum pressure,primary steam flow,NOx,SO2,and HCl are constructed to achieve short-term prediction of operational parameters,ultimately improving control performance.The anomaly recognition algorithm develops a thickness identification model for the material layer in the drying section,allowing for rapid and effective assessment of feed material thickness to ensure uniformity control.Meanwhile,the visual recognition algorithm identifies flame images and assesses the combustion status and location of the combustion fire line within the furnace.This real-time understanding of furnace flame combustion conditions guides adjustments to the grate and air volume.Integrating AI technology into the waste incineration sector empowers the environmental protection industry with the potential to leverage big data.This development holds practical significance in optimizing the harmless and resource-oriented treatment of urban domestic waste,reducing operational costs,and increasing efficiency.

Comment on the development and policy of the waste incineration power generation industry

Development space of the waste incineration power generation is expanding. According to the technical route of previous planning and related policies, the principles of our garbage disposal are based on sanitary landfill, supplemented by burning. However, with the accelerated process of urbanization, land resources are increasingly strained and most large cities have been unable to find a suitable landfill within the feasible urban extent, the main equipment for the incinerator and the localization of the overall process greatly reduced its capital investment and these factors will promote the rapid development of waste incineration power generation industry. Waste incineration and power generation technology has the dual benefits of environmental protection and energy and it is the development direction of waste disposal in the future. According to the condition that our country＇s waste incineration power generation started from scratch and developed rapidly in recent years ,there is a introduction about the application of the waste incineration and a brief analysis of the its obstacles in the promotion and financing, as well as the potential for future applications.

Study on China＇s Policy Text for Municipal Solid Waster Power Generation

Chinese government has initiated many preferential policies for supporting the circular economy, including the industry of municipal solid waste （MSW） power generation. This paper collects relevant policies for China＇s MSW power generation. It also analyzes the overall environment of policies for the MSW power generation from three aspects---the basic principles for China to develop MSW power generation, the operating mechanism and the specific preferential policies. The analysis establishes foundation for further research toward policy integration.

Comparative Study on Distributed Waste Pyrolysis Cold Emission Energy Station and Incineration Power Generation

The proper terminal disposal of organic solid waste such as domestic waste is a worldwide issue.Landfill covers a large area,with limited capacity,and a single landfill will be filled one day;incineration is costly to build and operate.These methods all need to transfer and centralized treatment,and secondary pollution is difficult to control,against the purification law of the nature."NIMBY effect"is very serious,and the social cost of treatment is increasing,becoming a heavy financial burden."The Distributed Waste Pyrolysis Cold Emission Energy Station"developed by Hunan Zhongzhou Energy-Saving Technology Co.,Ltd.overcomes these disadvantages and constructs a more appropriate environmental economic industrial chain for the treatment of organic solid waste such as urban and rural household waste.Based on its technical characteristics,this paper compares it with waste incineration power generation project in the aspects of secondary pollution control,treatment effect,energy utilization,investment and operation economy,etc.

HVAC Design Strategies for Municipal Waste Incineration Power Plants

In recent years,relevant government departments have achieved the goal of reduction and harmless application through the development and implementation of municipal waste incineration power plants,in order to advocate ecological and environmental protection.At present,in order to further achieve the goal of sustainable development,municipal waste incineration power plants have actively responded to the national call and requirements as well as made overall arrangements for the energy-saving design and optimization design of their internal system.Therefore,with the concept of sustainable development,this paper studies and analyzes the problems of the HVAC design as well as suggests related strategies for municipal waste incineration power plants in order to provide relevant reference.

Optimization of heat source side technical scheme of combined heat and water system based on a coal-fired power plant

Recovering the waste heat(WH)of a power plant can conserve energy and reduce emissions.Scholars have proposed utilizing the WH of power plants in a combined heat and water(CHW)system,which is considered an economical,energy-saving,and environment-friendly way to integrate water and heat supply into long-distance transportation in urban areas of northern China.However,to date,a detailed design of the case on the heat source side of the CHW has not been developed.Therefore,in this study,the heat source side of a CHW system was divided into two cases:a single-generator set and a double-generator set,and both cases were optimized.The parameters of a multi-effect desalination(MED)process were examined;the optimal number of evaporation stages during the MED process was 12,and the optimal heat source temperature during the first stage was 700C.Then,by matching the extraction and exhaust steam flows,the WH of the exhaust steam in the heating season was finally utilized.Further,under each case optimal conditions,energy,exergy,and cost were analyzed.The results showed that the exergy efficiency in the heating season for each case was approximately 50%,whereas that in the non-heating season was approximately 3.5%.The economy and water quality of the single-generator case were better than those of the double-generator case.However,the absorption heat pump required in the single-generator case is difficult to realize because it operates under two working conditions.

A Distributed Energy System with Advanced Utilization of Internal Combustion Engine Waste Heat

New trigeneration system consists of an internal combustion engine,a power and cooling cogeneration system and an absorption heat transformer system.The exhaust gas is recovered by the power and cooling cogeneration subsystem producing the cooling and power.The jacket water is recovered by the absorption heat transformer subsystem producing lowpressure steam.The exergy performance and the energy saving performance which is evaluated by the primary energy saving ratio of the new distributed energy system are analyzed.The effects of the ratio of the output power and cooling of the power and cooling cogeneration subsystem and the generator outlet temperature of the absorption heat transformer subsystem to the primary energy saving ratio are considered.The contributions of the subsystems to the primary energy saving ratio are quantified.The maximum primary energy saving ratio of the new distributed energy system is 15.8%,which is 3.9 percentage points higher than that of the conventional distributed energy system due to the cascade utilization of the waste heat from the internal combustion engine.
