Moreover , the furnace arch improvement has been carried on about the chain boiler dzl6 - 1 . 25 - aii of the boiler house in southvvest jiaotong university , which has improved the furnace ' s exit temperature and the thermal efficiency of the boiler
并对西南交通大学锅炉房的dzl6 - 1 25 - a型链条锅炉进行了炉拱改造，提高了该锅炉的炉膛出口温度和热效率。
In this thesis , designing " a " furnace arch by applying momentum synthesis and applying the laminar coal supply device to improve the burning in furnace , the operation duty of chain boiler , the thermal efficiency of boiler , are studied , according to the problems of the irrationality on boiler proper frame and the disproportion on system disposition in the design and the operation of chain boiler
本文根据链条锅炉设计和运行中存在锅炉本体结构上的不合理、系统布置上的不匹配等问题，研究了利用动量合成法设计“ ”型火焰炉拱，以及利用分层给煤装置来强化炉内燃烧，改善链条锅炉运行工况，提高锅炉热效率。
