Technical Solutions on Retrofitting TPP-210A Boilers for Firing Low-Grade Coals with Low Reaction Capacity

摘要

Results from development of a conceptual project for retrofitting TPP-210A boilers worked out by specialists of EMAlliance are described. Operation of the TPP-210A boilers installed at the Tripolskaya thermal power station is subjected to a comprehensive analysis. The existing difficulties connected with firing anthracite culm are considered. Two boiler retrofitting versions involving the use of a regenerative or tubular air heater are proposed. The advantages of the retrofitting version involving installation of a tubular air heater are described.
