Since the mid 1970’s, SPIE Hotwork has been performing dryout and heatup services to Coke and Carbon Calciners. The first calciner fired by SPIE Hotwork was inside a refinery in 1975 on the banks of the Houston Ship channel. SPIE Hotwork has performed dryouts on kilns, coolers, transition chutes, settling chambers, pyroscrubbers (afterburners), hot stacks and waste heat boilers.
