Development of and Experience With a New Generation of Modern Coal Firing Systems in a New High-Efficiency Combined Heat and Power Station

摘要

A new, highly advanced Combined Heat and Power Station which links a steam turbine with a coal-fired main boiler and a gas turbine waste heat system with a total electric output of 381 MW was commissioned in the summer of 1997. The main boiler is equipped with a new generation of pulverised coal firing systems. This new system combines ultra-low NOx vortex burners with a tangential firing concept. The firing system, including the new PF burners, has been developed and tested over the last 5 years including extensive computer modelling and tests on a pilot scale furnace.
