【摘要】：近年來隨著國內外經濟政策的影響，焦化行業(yè)變的不太景氣，限產政策出臺仍沒有改善該行業(yè)的虧損狀況，因而需要對焦化行業(yè)內部相關的能源結構、節(jié)能體系進行梳理，找到合適的節(jié)能措施，挖潛增效。本文分析了焦化行業(yè)的上升管能量回收、干熄焦余熱回收、煙道氣余熱回收，最終確定采用新型熱管鍋爐技術，建設河北JH公司的煙道氣余熱進行回收利用工程項目。本文采用項目管理方法對河北JH焦化公司的焦爐煙道氣余熱回收項目進行技術經濟分析，一方面對老焦化廠進行節(jié)能改造，另一方面也有利于新焦化廠的融合。 本文從理論上對項目立項前的準備工作、項目立項的研究工作進行闡述，從項目的工程建設實際對項目進行技術分析、經濟分析及財務評價，指出了項目的可行性。在技術層面加深對酸露點、熱管壽命的認識，，對余熱鍋爐布置方式，以及操作壓力設置，自動化控制等技術方案進行完善，從經濟、財務層面對項目的投資、利潤、效益、盈利能力、項目償還能力等進行了分析。圍繞項目管理的安全、質量、進度和費用四大要素，提出新穎的煙道氣余熱回收方案，并將研究應用到實際工程中，從JH公司的項目入手，為進一步探索焦化行業(yè)節(jié)能方法，實現(xiàn)焦化行業(yè)的節(jié)能減排開創(chuàng)了新的途徑。將項目管理引入到焦化行業(yè)煙道氣余熱回收中，對焦爐煙氣余熱回收進行指導、監(jiān)控，管理，并將新型焦爐煙道氣余熱回收項目在整個焦化行業(yè)推廣，應用，為焦化行業(yè)的技術創(chuàng)新，節(jié)能減排和挖潛增效做出貢獻。
[Abstract]:In recent years, with the impact of domestic and foreign economic policies, the coking industry has become less prosperous. The introduction of the production restriction policy has not yet improved the deficit situation of the industry, so it is necessary to comb the energy structure and energy saving system related to the coking industry. Find appropriate energy saving measures to tap potential and increase efficiency. In this paper, the energy recovery of rising pipe, the recovery of waste heat of dry quenching coke and the recovery of waste heat of flue gas in coking industry are analyzed. Finally, the project of recovering and utilizing waste heat of flue gas of Hebei JH Company is established by adopting new heat pipe boiler technology. In this paper, the project management method is used to analyze the technology and economy of the coke oven flue gas waste heat recovery project of Hebei JH Coking Company. On the one hand, the old coking plant is reformed with energy saving; on the other hand, it is beneficial to the integration of the new coking plant. In this paper, the preparation work before the project establishment and the research work of the project establishment are expounded theoretically, and the feasibility of the project is pointed out through the technical analysis, economic analysis and financial evaluation of the project from the project construction practice. To deepen the understanding of acid dew point, heat pipe life, layout mode of waste heat boiler, operation pressure setting, automation control and so on, from the economic and financial aspects to the project investment, profit, benefit, etc. Profitability, project repayment ability and so on were analyzed. According to the safety, quality, schedule and cost of project management, a novel waste heat recovery scheme of flue gas is put forward, and the research is applied to the actual project. Starting from the project of JH Company, the energy saving method of coking industry is further explored. The realization of energy saving and emission reduction in the coking industry has opened up a new way. The project management is introduced into the waste heat recovery of flue gas in the coking industry to guide, monitor and manage the waste heat recovery of coke oven flue gas, and to popularize and apply the new type coke oven flue gas waste heat recovery project in the whole coking industry. For the coking industry technology innovation, energy conservation and emission reduction and potential and efficiency to contribute.
