Hybrid units at Map Ta Phut are first of a kind
21 August, 2000
Phase III of the Map Ta Phut power plant in Thailand includes two 230 MWe units using a highly innovative Hybrid cycle, which can use both gas and coal as fuel. They went into commercial operation in March 2000. The Hybrid is essentially the integration of a gas-fired plant with a coal-fired plant, using a heat recovery unit which transfers heat from the gas side to the coal side of the process. The Hybrid is more efficient and more cost effective than building separate coal and combined cycle units.

Integrated heat and power plant supplies copper facility at Gresik
20 April, 2000
When Mitsubishi Materials Corp planned a copper smelter and refinery in Indonesia, the company asked BOC to bid to supply oxygen for the process. This invitation led to development of an integrated scheme for supplying power and steam to both the oxygen production unit and the copper smelting and refining plants. The result was the Gresik cogeneration project. Brian Keenan, BOC Gases, Guildford, UK
Simulating the realities of cogeneration
21 January, 2000
Most CHP plants are operated from the steam host control room and feed the local electricity grid. Training operators to operate such plants is becoming increasingly important. Using simulators to enable a trainee to learn how to operate a plant is one possible solution.
