The Pukchang Thermal Power Complex devised and introduced technical innovations for raising thermal efficiency of a boiler to finish the general overhaul of several boilers.

The complex completed the system of automatic combustion control by analyzing oxygen concentration to promote combustion efficiency with less coal consumption.

The Pyongyang Thermal Power Plant introduced the new technology of dust removal so as to raise thermal and combustion efficiency.

The plant produced and installed home-made turbine blades for promoting turbine efficiency than before, thus ensuring stable power production.

The Chongchongang Thermal Power Plant, the East Pyongyang Thermal Power Plant and the Sunchon Thermal Power Plant propel the work for readjustment and reinforcement and technical updating of generating equipment.
