High Mass Flux Coal Gasifier Extended Run Operations:Phase II Program. Second Quarterly Technical Progress Report,May--July 1977.

摘要

Two reactors have been designed and are being fabricated during the Phase II program,and the test facility is being modified to accommodate one-hour duration tests. Thermodynamic equilibrium analyses have been conducted to establish the best operating conditions for Lignite,Montana Rosebud and Pittsburgh Bituminous coals when reacted with air. Gasification tests will be conducted using these three types of coal. The gasifier will operate at a total mass throughput of nominally 20,000lb/hour cu. ft. of reactor volume and the coal flowrate will be nominally 0.5tons/hour. Test results will be analyzed to determine reactor performance and durability,and to evaluate the High Mass Flux Gasifier concept as a gas producer. Test results will be used to upgrade the scaled-up reactor design concept presented in the Phase I Final Report. Performance calculations for the reactions of coal/air/water and coal/air/steam were completed and reactor initial operating conditions selected. Considerable progress was made with test facility modifications required to accommodate one-hour duration testing. Despite this progress,test facility buildup was running approximately four weeks behind schedule at the end of the reporting period. It is currently planned to complete facility fabrication and checkout during the month of August and to then initiate reactor testing. A delivery of approximately 3000pounds of dried and pulverized North Dakota Lignite was received from C--E Raymond,the pulverizing vendor. Moisture content and particle size tests are currently being run by Bell. (ERA citation 03:046217)
