Gasification of Brown Coal in a Swirl-Type Gasifier with Microwave Torch Plasmas |
| 초록 |
We report the gasification of brown coal by making use of microwave plasma torches, which are installed to a swirl-type gasifier. The atmospheric-pressure microwave torch plasmas are operated at 915 MHz and a high flow rate of pure steam. The steam torch plasmas contain also highly active species, enhancing the chemical reaction rate and eliminating the need for catalysts in gasification processing. Upper and lower plasma torches are installed tangentially to the cylindrical gasifier sidewall. A swirl flow occur from the upper stage to down to the lower stage, thus making particle residence times much longer than that of a gas stream. The experimental results of gasification showed the output gas composition of 3.411 kmol/hr-H2, 2.742 kmol/hr-CO, 1.56 kmol/hr-CO2, 0.867 kmol/hr-N2, and 1.903 kmol/hr-H2O at given input parameters. |
