Gas turbines combust natural gas to generate high-temperature exhaust gas.

1. 1External air is compressed by an air compressor to provide combustion air.
2. 2In the combustor, air is mixed with fuel (natural gas) and ignited.
3. 3The combustion gas rotates the turbine connected to the generator.
4. 4Power is generated in the generator connected to the turbine.
5. 5The gas turbine is rotated, and the exhaust gas that exits through the exhaust duct is sent to the heat recovery steam generator.

Heat recovery steam generator utilizes the heat from gas turbine exhaust gases to generate steam.

1. 1The high-temperature exhaust gases discharged from the gas turbine are directed into the heat recovery steam generator.
2. 2Heat recovery steam generator uses gas turbine exhaust gases to produce steam, which is then sent to either a steam turbine or a district heating water heater.

It generates electricity using steam and also heats using the generated heat.

1. 1The high-pressure steam is used to rotate a turbine, and the resulting steam is directed to a district heating water heater.
2. 2The steam that comes out after turning the turbine is converted into water as it passes through the heating water heater.

It produces 115°C heating water using the 1st, 2nd, and 3rd heat exchangers.

1. 1The remaining heating water, used for district heating, is sent to the 1st, 2nd, and 3rd heat exchangers.
2. 2Hot steam is supplied from the steam turbine.
3. 3The hot steam is passed through the heating water heater to heat the heating water.
4. 4The heat of the heating water is supplemented by the heat generated from the LNG boiler and incineration plant.
5. 5The remaining heat in the heat accumulator is stored or used to supplement any heat shortage, and it is delivered to district heating users.

It supplies hot water from the user's mechanical room to each household or office.

1. 1Using hot water supplied from Incheon Total Energy at temperatures ranging from 75°C to 115°C, heating and hot water for each home and office are heated through heat exchangers installed in the mechanical room.
2. 2The cooled heating water used in each home and office is recovered to the mechanical room, reheated through the heating heat exchanger, and supplied again.
3. 3The hot water used is supplied to each home and office by heating tap water through heat exchanger.
4. 4Inside the mechanical room, heat exchangers for heating and hot water are installed, and there are various heat usage facilities such as automatic control systems and pumps.
