The present report is a summary of the activities in February and March 1995. The primary activities during these two months was to monitor the fabricator of the combustor extension in order to assure completion of the work according to the design, to procure the additional components needed to install the combustor-boiler system at the Arsenal test site, and on initial installation of auxiliary components at the site. Welding of the combustor extension major sections began in mid-January. However, the quality of the welds was poor and a number of non-critical flanges were warped during welding. As a result the fabricator replaced the welders and the quality assurance personnel in early February. To assure that the welded sections would properly mate with the existing combustor, Coal Tech personnel regularly visited the fabricator until the end of March. The combustor extension section was completed and delivered to the Arsenal at the end of March. To meet the Philadelphia particulate emission standard of 0.06 lb/MMBtu a baghouse was procured in February. Competitive procurement of the stack ducting from the boiler to the baghouse and to the atmosphere was initiated. Pneumatically controlled valves for the combustor extension section`s air cooling sub-system were ordered and delivered
