Refractory experience in circulating fluidized bed

Commercialization of coal-water slurry (CWS) is within reach, but utilities still require evidence that they can fire CWS in full-scale boilers over the long term. This study lays the groundwork for a one-year CWS demonstration, outlining a test program and calculating retrofit and operating costs for seven typical oil-fired boilers.
