PG650t/h型锅炉由于炉内结渣和排烟温度高使锅炉运行的安全性和热经济性受到严重影响，试验研究表明主要原因是燃烧系统存在缺陷以及设备和烟道漏风，指出提高锅炉热经济性应从完善燃烧系统、合理组织配风和堵漏３方面采取措施。
PG650t / h boilers due to slagging and high exhaust temperature of the boiler operation safety and thermal economy have been seriously affected, the pilot study showed that the main reason is the existence of defects in the combustion system as well as equipment and flue air leakage, pointed out that raising the boiler heat The economy should take measures to improve the combustion system, rationalize the distribution of wind and plugging.
