A Process For Enhancing The Calorific Value Of Syn Gas Generated From Fluidized Bed Coal Gasification Of High Ash Coals For Power Generation

Abstract: The invention relates to a process for enhancing the calorific value of syn gas generated from fluidized bed coal gasification of high ash coals for power generation comprising increasing the lower calorific value of the syn gas (16) upto 60% generated through the fluidized bed coal gasification process by admitting oxygen enriched air and steam as fluidizing medium (13), wherein value is increased by varying oxygen weight percentage in air of the fluidizing medium (13) from 23 % to 43 % including an increase in coal mass flow rate upto 73 % decreasing air mass flow rate upto 44% and enhancing steam mass flow rate upto 120%.
