CC-88 Combustion Efficiency Tests Successful in Indonesia on recirculating fluidized bed boilerWorking with PT Mitra Cahaya Mukti, PT Himalaya Tunas Texindo and ACCC, CC-88 combustion catalyst was added to the FBC unit and demonstrated improved combustion efficiency in a circulating fluidized bed boiler burning a common type of Indonesia coal.
By: Evan W. Lipstein, CEO Asia Coal Catalyst Company The purpose for this CC-88 demonstration on a recirculating fluidized bed boiler was to determine how much less coal would be burned while injecting CC-88 under controlled conditions. Our primary method to determine combustion efficiency was to determine the total number of tonnes of steam being produced matched to the exact number of tonnes of coal being burned, before and after combustion catalyst CC-88 was injected. Data collected includes: ● Boiler furnace temperatures ● Coal feed rate to boiler ● Steam production ● Emissions of particulate, O2 ● Fly ash analysis and bottom ash analysis for carbon content ● Exit flue gas temperature ● Daily log data The final report documents findings that CC-88 combustion catalyst showed an improvement of 4.91% at 0.5 kg CC-88 / ton of Coal and resulting combustion improvement of 5.55% at 1.0 kg CC-88/ton of coal. See the report from PT HIMALAYA TUNAS TEXINDO. http://www.coalcatalyst.com/ The Reports Conclusions: Based upon Indonesia ITB (Institute Technology Bandung), laboratory tests on the Himalaya Tunas Texindo (HTT) fly ash produced during trials done in September 2011, produced an improved combustion efficiency (or reduced coal quantity) of 4.91% at 0.5 kg CC-88 / tonnes of Coal and resulting combustion improvement of 5.55% at 1.0 kg CC-88/ton of coal. Observations of the slag within the boiler indicate that the CC-88 was beginning to remove the slag at the end of the demonstration cycle. Boiler Slag is an insulator and when it collects on the boiler tubes it reduces the rate of heat transfer. Notes about CC-88 Slag Removal: CC-88 will remove slagging and help maintain a clean operating boiler. To remove accumulated slag, a higher dose of CC-88 can be used initially for a period of 45 to 60 days. At the end of this period, CC-88 can then be reduced to its nominal designed feed rate and the slag will not form on heat transfer surfaces again. Slagging of boiler tubes is very common for some types of coal. When this occurs, costly downtime is necessary to clean out the boiler components. In some instances, additional power needs to be purchased by a user to meet sufficient power requirements. With the use of CC-88 clean coal combustion catalyst, the cost incurred from added shut downs due to slagging and related maintenance can be eliminated as well as the cost of buying power to replace power lost during shut downs. The demonstration conducted at PT HIMALAYA TUNAS TEXINDO showed a return on investment (ROI) for HTT resulting in a 4.91% net coal cost savings. CC-88 showed significant reduction to the unburned carbon within the fly ash and bottom ash which indicates an excellent reaction of the CC-88 catalyst with the coal and provides backup to the percent improvements in combustion efficiency and reduction in coal demand. HTT can now consider to produce more steam adding their production capacity in textiles or using less coal to maintain same production of steam for the time being.
