Kiln 3 burner project at Trinidad Cement Ltd

摘要

CEMEX continues to execute its long-term investment strategy in TCL, its Trinidad & Tobago-based subsidiary. TCL is the nation's sole cement manufacturer and has been steadily improving its quality, safety and efficiency to align to international standards. TCL is located in Claxton Bay, Trinidad & Tobago. It operates two wet process kilns, kilns 3 and 4, both of which are fueled by natural gas. Kiln 3 (HOOt/day, L = 145m, 0 = 5.2m) was commissioned in the mid 1980s. It has a specific heat consumption of 1730kCal/kg of clinker. The burner in kiln 3 was essentially a pipe that did not facilitate any flame control, leading to frequent refractory failures, low clinker quality control and excessive fuel use. The burner was also floor-mounted, which limited the space available during shutdowns, leading to poor safety conditions during shutdown and maintenance.
