DEVELOPING FUEL FLEXIBLE USC CFB TECHNOLOGY TO DELIVER LOWER COST GENERATION AND ENERGY SECURITY

摘要

There is an emerging requirement in Asia to utilise lower quality fuel for security of supply and drive down the cost of electricity. Pulverised coal boiler designs have been the technology of choice however development of a design that has much greater fuel flexibility at no extra capital cost needed another solution. Doosan is developing a 660MWe class USC CFB boiler concept for demonstration incorporating the proven aspects of both the Doosan Lentjes CFB combustor design and unique ash flow control technology with the Doosan Babcock patented Posiflow~(TM) low mass flux vertical tube furnace technology to deliver the new USC CFB boiler design.
