Cost of boiler tube failures 9/4/2013 Steag OM Company 7 The cost of boiler tube failures is comprised of three main components the cost of the repair the cost of start up oil to return unit to service and the cost of lost production A rule of thumb for repair costs of 200000 per day out of service+ cost of material

Therefore the appropriate design is CFBC Although development of CFBC technology has been slow (presently only 2% of the world's coal-based power plants use it) it is particularly suited for coal with lower heat content and high sulfur The efficiency of its large-sized units (i e over 300 MW) can be similar to that of PCC units 8

CFBC as an alternative to pulverised coal combustion (PCC) uses a fluidised bed an apparatus that mixes coal and air with a sorbent such as limestone during the combustion process to facilitate more effective chemical reactions and heat transfer In a fluidised-bed combustor combustion occurs when the
