发布时间：2018-11-12 09:29
【摘要】：近年来随着国内外经济政策的影响，焦化行业变的不太景气，限产政策出台仍没有改善该行业的亏损状况，因而需要对焦化行业内部相关的能源结构、节能体系进行梳理，找到合适的节能措施，挖潜增效。本文分析了焦化行业的上升管能量回收、干熄焦余热回收、烟道气余热回收，最终确定采用新型热管锅炉技术，建设河北JH公司的烟道气余热进行回收利用工程项目。本文采用项目管理方法对河北JH焦化公司的焦炉烟道气余热回收项目进行技术经济分析，一方面对老焦化厂进行节能改造，另一方面也有利于新焦化厂的融合。 本文从理论上对项目立项前的准备工作、项目立项的研究工作进行阐述，从项目的工程建设实际对项目进行技术分析、经济分析及财务评价，指出了项目的可行性。在技术层面加深对酸露点、热管寿命的认识，，对余热锅炉布置方式，以及操作压力设置，自动化控制等技术方案进行完善，从经济、财务层面对项目的投资、利润、效益、盈利能力、项目偿还能力等进行了分析。围绕项目管理的安全、质量、进度和费用四大要素，提出新颖的烟道气余热回收方案，并将研究应用到实际工程中，从JH公司的项目入手，为进一步探索焦化行业节能方法，实现焦化行业的节能减排开创了新的途径。将项目管理引入到焦化行业烟道气余热回收中，对焦炉烟气余热回收进行指导、监控，管理，并将新型焦炉烟道气余热回收项目在整个焦化行业推广，应用，为焦化行业的技术创新，节能减排和挖潜增效做出贡献。
[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.
