Industrial Application of Jetting Fluidized Bed Coal Gasifier with a Cone-shaped Distributor

This paper introduces the facility of jetting fluidized bed coal gasifier with a cone shaped distributor and its gasification process.A brief introduction on the principle of gasification and ash agglomeration was also included here.Distribution of furnace temperature along the gasifier height was measured during the running time.Variation of the bed temperature on fluidization airflow rate and central spouting airflow rate was investigated.Furthermore,we studied the effects of bed temperature on gas components and carbon conversion rate.From tests,it can be proved that proper gasification temperature is at the range of 960 to 980 ℃.
