Abstract/Notes A thermal extraction cone chamber system has been modified to measure differential thermal functions and products where overall volatile organic matters are lost to the environment during heating. The aims of the research are to analyze and measure the thermal behavior of high un-burnt carbon coal fly ash derived from textile industrial power in Bandung. Efforts are being made to find the solution in large-scale utilization for alternative energy based on their by product. The sampie analysis show that volatile organics matter exceed 30 percent, which means that others oxides element content are independently favorable. The modified cone chamber can collect the sample up to the total volumes of 30 percent of the chamber. In contrast to traditional chamber sampie collectors, the modified cone extracts volatiIe organics matter from high un-burnt carbon coal ash divided in two treatments. Results show that the energy of pyrolisis, direct combustion or simple carbonization can be recovered (20 percent - 42 percent) from wet or dry sample, with extraction efficiency compound-specific. During the direct combustion experimentation, resulted to the embedded energy is pushing up to 279 derajat Celcius for the average of volatile organic matters of 34 percent and for pyrolisis experimentation is 330 derajat Celcius for average volatile organic matters of 30 percent. The maximum thermal productivity values of 80 minutes for the direct combustion is 1022 derajat Celcius and for pyrolisis is 1031 derajat Celcius, and the contrary of 10 minutes, for the direct combustion is 743 derajat Celcius and for pyrolisis is 701 derajat Celcius.
