摘要：我国石油焦焕烧以罐式焕烧炉和回转窑为主。罐式焕烧炉是我国最早采用的一种焕烧设备，能够焕烧不同挥发份含量的生石油焦，具有锻烧料质量稳定，炭质烧损率低，焕后焦的堆积密度高，操作简单、维护工作量小、连续生产的周期长等优点，固此广泛应用于大、中小炭素厂和铝用炭素行业中。罐式炉焕烧过程产生大量烟气，风温很高，通常高达950℃以上，供导热油炉的部分用热后烟气也有600℃。烟气热烩高，可利用其来生产蒸汽进行发电，既能有效提高企业自供电率，实现企业节能减排降耗增效，可取得良好的社会效益、经济效益和环境效益。本文介绍了罐式焕烧炉烟气余热利用发电的可行性。

Abstract: The main buming methods of petroleum coke in our county are pottype calciner and rotary kiln. Pot - type calciner is the earliest buming equipment used in our country which can bum raw petroleum coke with different volatile content, Its advantages include stable quality of buming material, low buming waste of carbon, high coke piling density afier buming, easy operation, low maintenance and long period of continuous production, so the pot type calciner is used widely in the carbon factory of middle and big sizes and aluminum carbon industry. Much gas is produced during the buming of pot type calciner, the gas temperature is usually over 950°C and it could be 600℃ even afer using by heat conducting oil boiler. The high enthalpy of gas can be used to produce steam to generate electric power, which could increase the electricity supply for the company itself to realize energy saving and waste -reducing, better social, economic and environmental benefits could be gained. This paper introduces the Feasibility of using Waste heat to generate electric power which comes from the gas of pot type calciner. Key words: Pot type calciner gas; Using Waste Heat to generate electric power; Energy saving and wastereducing;Economic benefits;Social benefits
