Usage
- Supply electricity, steam, and purified water to businesses in Yeosu Industrial Complex
Features
- By taking advantage of the waste heat, electricity and heat energy are produced at the same time to improve the overall energy usage efficiency (75-90% of energy efficiency and 20-30% of energy saving)
- As a distributed power supply source, it can be used for power peak-cutting in summer and winter and contribute to stable power supply
- Supply full-year stable utilities by operating multiple sites and backup facilities
- Help reducing the cost of equipment and power transmission loss due to remote transmission
- Contribute for improved environment conditions by reducing the fuel usage and by concentrating on antipollution facility management (30% or more reduction of pollutant)
Advantages
Starting with 2 gas boilers, we were certified as a private group energy provider in 1993 and obtained the electricity sales right as a private business in 1995. With diversification of fuel (TDF, Bio-SRF, etc.) and introduction of extraction back-pressure & extraction-condensing cogeneration facilities and passive equipment, we have promised stable production of our clients and aggressively contributed to national energy saving policies. As a CFBC boiler leader of Korean market, we are procuring coal from our logistics subsidiary, Kumho T&L, as a stable source and leading R&D for various types of solid fuel.

A. Steam
| Type | Pressure kgf/cm2 | Temperature(℃) | Own Standard | |
|---|---|---|---|---|
| Steam | Main Steam | Approx.100 | Approx.480 | Conductivity: < 5㎲/cm pH: 8.5 ~ 9.2 SiO2: < 0.02ppm |
| Approx.128 | Approx.538 | |||
| High-pressure Steam | Approx.45 | Approx.330 | ||
| Medium-pressure Steam | Approx.25 | Approx.250 | ||
| Low-pressure Steam | Approx.10 | Approx.200 | ||
We are generating power by supplying turbine generators with steam generated from firing boilers and fluidized-bed boilers and offering steam of desired pressure by extracting it from the middle of turbines.
B. Electricity
| Type | Voltage | Frequency | Remarks |
|---|---|---|---|
| Electricity | 22.9 kV | Normal system frequency 60Hz | Power supply without interruption |
Without interruption, we are supplying power from ourselves and KEPCO to Yeosu Industrial Complex. Besides, we are contributing to protection of national electricity loss and electrical peak by back-feeding the power from our turbines to Korea Power Exchange.
C. Water
| Type | Own Standard | |
|---|---|---|
| Water | Demineralized water |
pH: 6.5 ~ 7.5, Conductivity: < 1㎲/cm SiO2: < 0.02ppm, Fe: < 0.01ppm |
| Purified Water | Turb: < 2 Deg | |
| Drinking Water | In compliance with water criteria from Ministry of Environment | |
Water goes through water filter and gravity filter bed to become purified water which is used to produce pure water through ion-exchange pure water production equipment so that we can provide purified/pure water.
