While we have concentrated over the years on the South African coal industry and most of our work has been within its borders, we have also demonstrated the feasibility of manufacturing the modular plants in our workshops and shipping them overseas.
This thesis consists of two parts. The first is a costbenefit analysis by the author of a waste to energy (WTE) plant in Montevideo, Uruguay; the second part is a description of WTE projects in various islands, some of which have succeeded and some are in various phases of implementation. Part 1: CostBenefit Analysis of a WTE Plant for Montevideo
Smallscale biomass electric plants have installed costs of 3,000 to 4,000 per kW, and a levelized cost of energy of to per kilowatt hour (kWh). The two principal types of chipfired direct combustion systems are stationary and travelinggrate combustors, otherwise known as fixedbed stokers and atmospheric fluidizedbed combustors.

Coal and coal preparation in South Africa—A 2002 review by D. Peatfield* Synopsis The design and operation of coal preparation plants are governed by the inherent quality of the raw coal to be processed, market specifications and the saleable tonnage requirements. Topography influences the layout of the plant but does not affect the process ...

Chapter 7 COAL If we as a nation are to benefit in the future from our enormous, lowcost coal reserves, a variety of efforts are necessary to (1) develop and demonstrate new "clean coal" technologies; (2) reduce uncertainty over environmental regulation and allow electric power plants (which use more than fourfifths of all the coal ...
A flow diagram of a 400 ton per hour coal plant that produces both metallurgical coal and steam coal for power generation. Generally speaking, metallurgical coal is cleaner, has higher carbon content and is easier to process than the lower rank steam coals. At this prep plant, all feed coal (ROM) is crushed to 2" before entering the plant circuits.

A half century later, we have learned that nuclear power is, instead, too expensive to finance. The first generation of nuclear power plants proved so costly to build that half of them were abandoned during construction. Those that were completed saw huge cost overruns, which were passed on to utility customers in the form of rate increases.
Before it closed, the Macquarie Coal Preparation Plant had to find a way to start capping its tailings dam while still receiving material from the nearby mine. Our team designed and tested a way for the Plant to progressively cap the tailings storage facility, reducing its closure costs.
