摘要
增压锅炉节能环保的优点使其具有良好的陆地工业应用前景。针对制造成本和技术要求高的缺点,提出使用罗茨风机代替附加汽轮机的工作方案;改用锅壳式布置形式,降低增压锅炉炉膛出口烟温。研究结果表明以上改进措施可以大幅降低增压锅炉生产成本,提高锅炉的承压及密封效果,解决耐高温材料限制。
The advantages of energy saving and environmental protection make the supercharged boiler having good application prospects of terrestrial industry.Aiming at solving the weakness of production cost and high demand of techniques,the work programme of using roots blower was put forward to instead of steam turbine,and changed to shell boilers and reduced the flue gas temperature of furnace outlet.The results show that these improvements can greatly reduce the production cost of supercharged boiler,and improve the boiler's pressure bearing and sealing effect,and also can solve the limitation of high temperature resistant materials.
