Advantages of Pet Coke Againts Gas Lignite Coal

Parameter Pet Coke Lignite Coal Gas / FO
GCV Very High - 8200 Kcal/Kg Guaranteed VERY LOW - 3000 to 3200 Kcal/Kg, Approx LOW - Varies from 4000 to 6200 Kcal/Kg Approx. 8500 to 9000 Kcal/M3
ASH Nil (< 1%) - Low Ash Related Pollution Problem - Also material unburnt is reusable as nil ash content. VERY HIGH (15 TO 30%) - Unburnt loss due to high Ash content - Ash Handling - Ash Related Pollution Problem - High Ash content in fuel causes Erosion of Boiler Tube MEDIUM TO HIGH - Percentage of Ash content varies from 10 to 20% or may be more depending upon different type of coal (Domestic/Imported) - This Ash content is some what lower than Lignite but definitely it is much higher than in Pet Coke. - So, Problem due to ash will remain same for Coal, as MENTIONED FOR LIGNITE. N/A
NATURE OF ITEM Manufactured Product NATURAL ITEM NATURAL ITEM NATURAL
QUALITY Consistent WILL VARY - As Natural Product WILL VARY - As Natural Product CONSISTENT
MATERIAL HANDLING Very Low - Nearly 2 - 3 times lesser than lignite HIGH - Approx 2 - 3 times higher than Pet Coke HIGH TO MEDIUM - Approx 1.5 - 2 times higher than Pet Coke ONLINE
GRINDING REQUIREMENT Very Low - Approx 20 to 25 % Material needs Grinding VERY HIGH - Most of the Material needs Grinding VERY HIGH - Most of the Material needs Grinding N/A
MOISTURE CONTENT LOW - Very Low Moisture - Does Not Suck Moisture by self HIGH - Has High Moisture - Does Suck Moisture from land and atmosphere HIGH - Has High Moisture - Does Suck Moisture from land and atmosphere N/A
VOLATILE MATTERS LOW - Low initial burning loss. - Also is Not Self Burning in Open space due to Heavy Sun Light HIGH - High Initial Burning Loss. - Get Self burning in Heavy Sun Light HIGH - High Initial Burning Loss. - Get Self burning in Heavy Sun Light -----
FUEL COST Per 1000 Kcal LOW - As Pet Coke Comes with Excise Modvat, Per 1000 Kcal Net of Modvat cost would be lower than that of Lignite NEARLY EQUAL - Cost of Lignite falls nearly same as Pet Coke. - But in Lignite other operating cost are high, such as Material Handling, Storing, and Grinding etc. - Also ash related pollution and disposal problems HIGH It costs somewhat higher than that of Pet Coke VERY HIGH Very high compared to Pet Coke Prices based on GCV
