摘要
介绍了一种循环流化床锅炉热风系统的设计,该系统的热源为一燃用玉米芯的循环流化床热水锅炉,燃料燃烧产生的热首先产生热水,热水在换热器内与空气换热,然后产生43℃热风。这套系统设计关键为锅炉的燃烧温度选择、灰渣质量平衡以及如何保证热风风温稳定等。为进行这套系统的设计,通过试验研究了玉米芯在流化床内的燃烧特性、灰渣结焦特性以及循环床回料器的回料特性。在试验基础上,设计了这套热风系统,这套热风系统由锅炉、换热器、调节系统、除尘器等组成。首台采用该技术的热风系统已在山东登海先锋种业公司投产。这套系统可作为设计燃用稻壳、秸秆等其他生物质燃料锅炉的参考。
This paper presented a research on CFB boiler hot air system. This hot air system consists of CFB hot water boiler, heat exchanger control device and dust catcher. The key equipment of this system is the CFB hot water holler which fired corn-cob which come from corn seed produet process. The important concern which must be resolved for boiler design is how to choice the appropriate boiler furrace exit temperature and how to keep the stable outlet hot temperature of heat exchanger. A experiment is conducted to study the combustion of corn-cob, corn-cob ash property. Based on the experiment result a boiler was designed and manufactured by Beijing Boiler Works. Through one year manufacture and erection this hot air system has come into commercial operation for one year. The practical operation shows that the corn-cob fired CFB is welcome by corn-seed process enterprise.
