摘要

垃圾的热值和成分是了解垃圾焚烧炉行为和优化其运行的关键运行变量。然而，由于垃圾的热值和成分变化很大，因此很难预测垃圾焚烧厂的热值和成分。为了克服这一问题，本研究开发了一种新方法，通过使用运行数据和基于物理的模型，采用反向计算算法得出垃圾的热值和成分。此外，还开发了一个过程模拟模型，用于预测垃圾焚烧炉系统的性能。我们利用假定的方法得出了目标焚化炉中废物的热值和成分，并通过过程模拟模型提出了提高废物焚化炉能源回收效率的运行策略。与现有焚化炉的运行相比，能源回收效率提高了约 10%。本研究开发的方法可应用于各种焚化炉系统。我们的研究结果有助于通过计算垃圾的热值和成分来确定垃圾焚烧炉的最佳运行方式。

Improving waste-incineration energy recovery efficiency using a reverse calculation algorithm to estimate waste composition and heating value

The heating value and composition of waste are crucial operational variables for understanding waste incinerators behavior and optimizing their operation. However, because the heating value and composition of waste are highly variable, their prediction in waste incineration plants is difficult. To overcome this issue, this study developed a novel method to derive heating value and composition waste via a reverse calculation algorithm using operating data and physics-based model. In addition, a process simulation model was developed to predict the performance of waste incinerator systems. We derived heating values and compositions of waste in the target incinerator using the supposed method and proposed an operating strategy to improve the energy recovery efficiency of the waste incinerator through the process simulation model. The energy recovery efficiency increased by approximately 10 % relative to that of the existing incinerator operation. The methodology developed in this study can be applied to various incinerator systems. Our study findings contribute to establishing an optimal operation of a waste incinerator by calculating the heating value and composition of waste.
