The Celje Heating Plant is the first facility in Slovenia for the thermal treatment of municipal waste and presents the final stage in the treatment of previously processed waste, preparing it for use in the Celje Regional Waste Management Centre. This satisfies the required properties for waste deposit pursuant to the requirements of Slovene regulations and European guidelines.
In accordance with the environmental permit, up to 30,000 tons of pretreated municipal waste - light fraction (LF) waste – with the waste classification code 19 12 10, and sludge (SWTP) with the waste classification code 19 08 05 from the Central Wastewater Treatment Plant, up to 30% of dry matter can be processed on a yearly basis.
This plant for the thermal processing of waste with an energy recovery process, flue gas purification, and a computer control and monitoring system follows the requirements of the recent technology discoveries in these fields. For the production of heat and electricity, the steam boiler unit with 15 MW of power and steam parameters of 30bar, 350oC and the amount of 20t/h, is built in.
15MW of energy can be generated in the production of energy from waste at the full power, of which is 2MW of electrical energy. Actual production will depend on the amount of waste delivered. The thermal energy released in the process is used for:
- remote heating system of the city of Celje and
- production of electrical energy, partly used for the plant’s own purposes, while the surplus energy is transferred to the distribution network.
The plant operates continuously 24 hours a day, 7 days a week. Approximately 8000 hours of operation is planned per year.
The technology procedure is illustrated below.
