Coal/Power Generation

DemcoTECH Engineering’s technologies for offloading trains, through to coal storage, and in-plant and overland conveyor systems, are supported by advanced testing, flow modelling and system simulation tools for these systems to be based upon a thorough understanding of the properties of the coal. Effective dust control systems are also critical in coal handling and DemcoTECH has an extensive track record in the supply of effective dust suppression and dust extraction systems, as well as in utilizing its in-house pipe conveyor design capabilities to contain, reduce and eliminate dust and environmental issues.

ESKOM, Majuba Power Station Coal Supply Facility Upgrade

Commodity: Coal; Contract Type: Concept Feasibility Study

DemcoTECH Engineering was appointed to investigate the existing coal delivery facility at the 6 x 700 MW Majuba power station with a view to upgrading the throughput and system reliability. DemcoTECH developed various conceptual designs and prepared a simulation model for the rail delivery, tippler and power station feed system in order to predict the required equipment capacity and the rail infrastructure modifications necessary to deliver 14 Mtpa of  coal reliably by rail.  Read more …

Port of Ploce Import Terminal

Commodity: Coal, Iron Ore; Contract Type: Detailed Engineering

DemcoTECH Engineering carried out the detailed engineering of the bulk materials handling on the stockyard at an import terminal project at the Port of Ploce. The multi-product terminal offloads and handles mainly coal, but also iron ore. The vastly different material properties of coal and iron ore had design implications for the system, particularly the chutes and train rapid rail load-out system, as well as the fact that the main stockpile is served by only one rail-mounted bucket wheel stacker reclaimer.

Tanjung Bin Coal Import and Distribution Facility

Commodity: Coal; Contract Type: Design & Site Supervision

DemcoTECH Engineering provided the design for the 5,000 tph conveyor system for the coal import and distribution facility at the 3,100 MW Tanjung Bin coal-fired power station located in Johor, Malaysia. DemcoTECH carried out Discrete Element Modelling (DEM) material flow analysis on all the chutes and also provided site supervision during erection and commissioning of the system.
