Numerical simulation based cold tests for a tangentially fired boiler
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.
