Firetube Boiler Fiber Burner Development Program. Final Report September 1982-September 1986

摘要

The results of a 48-month program to perform field evaluations of durability of the Pyrocore radiant fiber burner in gas-fired firetube boilers are presented. These activities included selection of four industrial test sites, testing of a prototype segmented burner, design, construction, and installation of the four field test units, and field testing of the boilers with both conventional and fiber burners. The burner designs and potential control schemes for achieving various turndown capabilities are discussed. The unique aspects of each test site and installation are described, and the test results and benefits over the evaluation period are presented. Burner modifications implemented to reduce cost and enhance reliability are included. Additional tasks to develop a fuel oil firing capability for dual fuel operation, and to improve the durability of the ceramic materials comprising the burner, are also summarized.
