摘要

Such problems as flameout and serious slagging frequently occurred in a 170 t/h tangentially fired boiler burning inferior coals and with low load.Thus

cold tests were carried out to comprehensively investigate the performance of each air tube and the size and position of the tangential circle.Therefore

the cause and area of slagging in furnace can be determined.Thus

by numerical simulation on combustion

the optimal operation parameters for the boiler burning different coals under various loads conditions can be provided.The actual application showed that

the boiler fed with present coal can be long-term operated stably at 60% load

and its heat efficiency was up to 91%.Moreover

the abnormal flameout no longer occurred

and the slagging was alleviated a lot.
