Design, Construction, Operation and Evaluation of a Prototype Culm Combustion Boiler/Heater Unit. Quarterly Technical Progress Report, April 1-June 30, 1983

摘要

This report provides a summary of the work performed on the Prototype Culm Combustion Boiler/Heater Unit, Phase I - Engineering Design and Analysis, Phase II - Prototype Plant Construction and Phase III - Start-Up and Operation during the period April 1, 1983 through June 30, 1983. The objectives of the program as well as the technical progress and problem areas encountered during the reporting period are presented. The Extended Test continued throughout April after which the plant was shutdown for final inspection and preparation for storage. An additional 528-1/2 hours of operation were accumulated during April bringing the total boiler operating time through the end of this quarter to 10,128 hours. Steam was delivered to the User (Cellu Products) during this time to generate steam revenue. During this period, a stack emission test was conducted which indicated particulate emissions well below the state requirement. Also, a short (100 hrs.) feasibility test was conducted using bituminous waste (gob) as fuel. The test demonstrated the successful combustion and sulfur capture characteristics of the fluidized bed combustion of this low heating value (3000 Btu/lb.), high sulfur (5%) fuel type. Data analysis and report preparation has continued throughout the period. A compilation of economic operating cost data was completed and forwarded to DOE and to Gilbert Associates of Reading, Pennsylvania for use in preparation of an operating cost analysis for the Shamokin Fluidized Bed Boiler.
