Mixing and gasification of coal in entrained flow systems. Quarterly technical progress report, 1 October 1975--31 December 1975
Work accomplished during the fourth quarter to investigate mixing and gasification of coal in entrained flow systems is presented. Technical visits to European laboratories conducting coal and combustion work are summarized. Review of numerical methods for treating recirculating flows in coal combustors was continued. Fabrication and installation of modifications to the nonreacting facility for measuring particle-gas mixing rates were completed. Fabrication of the low-pressure reactor sections was completed while fabrication of inlet sections was initiated. Final design of the high-pressure reactor was nearly completed and a fabrication schedule was identified. The primary oxygen preheater was received and the steam generator and secondary steam-oxygen superheater were ordered. Design of the reactor support and service systems was completed and parts ordered and received. Samples of pulverized coal to be used in the test program were analyzed by independent laboratories. Development of a macroscopic model of coal-gasification processes was outlined. Model assumptions, differential equations, and auxiliary equations were formulated. For a specified rate of mixing of primary and secondary streams and rate of recirculation of combustion products, the model includes effects of radiation, ignition, coal pyrolysis, char oxidation, and hydrocarbon reaction. A possible cooperative program for predicting the details of mixing and recirculation in coal gasifiers is also being considered.
