- Recovery Plant Description
Three sets of continuous mass burn mechanical grate combustion incinerators having a total capacity of 900 tons per day can treat almost 50% of the daily house garbage produced in Kaohsiung city.
There are three water-tube boilers that collectively have a total capacity of 128.4 tons steam per hour.
Turbines and Generators:
An extraction condensing turbine and generator having a capacity of 25 Mega-Watts will not only supply power required for the entire plant, but also transfer excess power to Taiwan Power Company (TPC) during normal operation.
CECI has successfully carried out the planning, design and construction supervision of the Kaohsiung Central Region Recovery Plant owned by the Department of Environmental Protection, Kaohsiung Municipal Government. Construction for the plant, located in the Fu-Den-Chi area of Kaohsiung city, started in 1995, and after three years of construction and one year of testing, the plant was commissioned for operation on April 30, 1999.
Its successful construction and operation symbolize the first step in resolving all problems associated with the disposal of house garbage in the southern port city of Kaohsiung. Types of systems used for processing the refuse include the following:
- Fly ash solidification system: The fly ash is collected after the burning process in the bag filter and transported to the fly ash silo by pneumatic ash conveyors. After solidification and fully satisfying the requirements for volume reduction and removal of harmful matter, the fly ash is transported to the landfill.
- Flue gas treatment system: The combustion temperature is controlled above 850℃ and the flue gas resident time is controlled for over 2 seconds. The dioxins will therefore be effectively destroyed and the off-gas can be ducted to a semi-dry absorb tower, where lime slurry is injected to remove the hydrochloric acid and sulfur dioxide acid gases from the flue gas. Afterwards, the gas is ducted to the stack and exhausted to ambient. Finally, two sets of continuous emission measurement systems supervise the flue gas quality.
