Power Generation

Samchully provides clean, convenient energy with safety.

Characteristics of combined heat and power generation

Combined heat and power generation refers to power generation by combing two types of a heat cycle. First, power is generated using the gas turbine, and exhaust gas is sent to the Heat Recovery Steam Generator (HPSG) to produce steam and turn the steam turbine for power generation in order to collect some of the calories left in the exhaust gas (over 500℃) emitted to the air. Currently, the heat efficiency of the combined cycle is almost 50% and is expected to reach 60%.
