Calaveras Power Partners LP – Chimney Liner Construction

Location: San Antonio, Texas

Calaveras Power Partners LP awarded ǧý a project for the construction of a 28 foot diameter chimney liner which is 602 feet tall at their J.K. Spruce (JKS) Power Plant in San Antonio, TX. The coal fired electric generating station owned by City Public Services’ at Calaveras’ site powers 750 MW of power. This is the 3rd stack at this power plant. The scope of work for this cost plus contract was to engineer, fabricate, procure, construct and install the liner for the exhaust of the coal fired plant located southeast of San Antonio. The top 20 feet is composed of solid hastelloy, which requires special welding. The balance of the stack is carbon/hastelloy clad material which also requires special handling and welding.
