Erosion can significantly reduce the operational life of boiler components. Abrasion-resistant ceramic parts can be a sound alternative to expensive metallic parts when replacing boiler components.

If the basic science related to man’s contribution to a warming planet is based on flawed fundamental science, a conscious circumventing of the peer review process, political expediency, and refusing to release the fundamental data used by a computer program that has yet to replicate actual ambient temperatures, then it’s time to pause, take a breath, and regroup.

When the Łagisza power plant began commercial operation in late June 2009, it marked the beginning of a new era in the evolution of circulating fluidized bed (CFB) technology. At the heart of this 460-MW plant is the world’s largest CFB boiler, which is also the world’s first once-through unit supercritical CFB boiler.
