摘要

许多工业废气，特别是来自化学和石化过程的废气，含有可燃物质，使其成为一种有前途的能源。热氧化代表了一种合适且成熟的技术，然而，就依赖于废热回收效率的外部燃料需求而言，热氧化是非常耗能的技术。本文提出了一种系统的方法，用于工业装置的废气热氧化(废气发电装置)的能源改造，以提高装置的废热回收，从而减少外部能源需求。这降低了运营成本和排放，提高了废气能源利用率。该方法程序进一步应用于特定废气发电装置的能源改造，通过提出的概念修改，节省了30%以上的燃料，投资回收期仅为5.5个月。最后，通过对比，成功验证了该方法的准确性

Conceptual Design Method for Energy Retrofit of Waste Gas to Energy Units

Many industrial waste gasses, especially from chemical and petrochemical processes, contain combustible substances enabling their utilization as a promising energy source. Thermal oxidation represents a suitable and proven technology, which is, however, very energy intensive in terms of external fuel demand dependent on exhaust heat recovery efficiency. This paper presents a systematic method developed for the Energy Retrofit of industrial units for thermal oxidation of waste gases (waste gas-to-energy units) in order to improve the units´ waste heat recovery and thus to reduce the external energy demand. This results in the reduction of operational costs and emissions and improves waste gas energy utilization. The method procedure is further applied to Energy Retrofit of a specific waste gas-to-energy unit, where the fuel saving of over 30% was achieved by the proposed conceptual modifications with a payback period of only 5.5 months. Finally, the developed method accuracy was successfully verified by comparison with
