The major cost components in the power station are:
Purchase costs of fuel
Fuel handling and storage
Efficient combustion of fuel
Unscheduled failures, or plant outages
Disposal of waste products, including treatment of wastes to permit disposal.
Power stations operate in a variety of modes, ranging from "mine mouth" stations, which receive coal from a single nearby source, to remote stations located at load centres, which receive coal from multiple sources. These operating modes also influence stockpile management; a power station close to the mine may receive coal by truck or by overland conveyor and thereby hold minimal stocks, the "just-in-time" approach, whereas a power station reliant on long rail hauls or sea freight to obtain coal may hold larger "live" and "long term" stockpiles. The "just-in-time" operation has little opportunity to blend coals to even out quality variations, whereas the "remote" station can use its stockpiles to advantage.
On-line analysers can monitor the quality of coal feed and waste products, allowing power station operators and management to optimise the performance of the station by making decisions based on knowledge in advance, rather than reacting to changed conditions as they arise.
Scantech International | Real Time Analysis of Bulk Conveyed Materials
Scantech is the world leader in the application of on-line real-time measurement technologies for bulk materials. Scantech has over 1,000 analysers installed in 55 countries. Founded in 1981, the company has grown from a small private company based in South Australia to a successful public enterprise with an international business focus.
The platform for the company's early success was the commercialisation of scientific instrumentation developed by the CSIRO and the University of Queensland, resulting in the highly successful COALSCAN range of real time coal analysers. Since that time, new technologies have been developed using in-house R&D resources, whilst continuing to seek suitable technologies from external sources.
The company has developed and implemented a Quality Management System (ISO 9001:2008 BV Certified), assuring its customers of quality, safety and reliability of its products, production processes and services.
