What is coal gasification ?
It is a process in which coal, air or oxygen and steam react under conditions of certain temperature and pressure to produce a low or medium calorie fuel gas. Air or oxygen undergoes combustion reaction with part of the carbon in the coal and releases exothermic heat. The balance carbon undergoes gasification reaction with steam, hydrogen and carbon-dioxide, thereby utilizing the exothermic heat released in combustion reaction. Types of gasification process Moving bed gasification process Fluidized bed gasification process Entrained bed gasification process Choice of the process Fluidized bed gasification process for high ash Indian coals

Coal Gasification Technologies
Entrained Flow Moving Bed Fluidised Bed Coal size <250 microns 5-30 mm Less than 6 mm Ash % <20 <25 No limitation Ash fusion C <1350 Effluent Waste water Tar, oils, phenol Effluent treatment Relatively less expensive Gasifier area 1.0 3.0 1.6 IGCC maturity Large plants working Demonstrated in 6.2 MW

ADVANTAGES OF PRESSURISED FLUIDISED BED GASIFIER
HIGHER UNIT CAPACITY PER UNIT AREA IN - BED SULFUR REMOVAL OPTION NO TAR OR OIL FORMATION AND EASY GAS CLEANING NO LIQUID EFFLUENT FORMATION ABILITY TO ACCEPT FINER COALS CAPABILITY TO ACCEPT WIDE VARIETY OF COALS BETTER RELIABILITY AND CONTROL OPERATES IN NON-SLAGGING MODE BEST SUITED FOR HIGH ASH INDIAN COALS LOWER CAPITAL AND OPERATING COST COMPARED TO ENTRAINED - BED GASIFIER

Fluidised Bed Gasification
Advantages Air used as reactant instead of Oxygen high cost/power consumption of oxygen plant avoided Low Temperature Operation Reliability issues due to high temperature operation eliminated In-situ removal of Sulfur, trace elements Dry granular ash Large Fluidised Bed Combustion systems in reliable operation Issues Low Calorific Value of Gas (1100 – 1250 Kcal/NM3) Comparatively high un burnt in ash

Fluidization engineering-Applications
Fluidized beds are used as a technical process which has the ability to promote high levels of contact between fluid (Liquid/gases) and solids. In addition, it has following advantageous characteristics: High surface area contact bet fluid and solid per unit bed volume High relative velocities between the fluid and the dispersed solid phase. High levels of intermixing of the particulate phase. Frequent particle-particle and particle-wall collisions Uniform temperature throughout the fluidised bed
