Drying Refractory in SteamGenerating Boilers Insulation
Drying refractory is critical for strong, longlasting refractory applications Unfortunately, standard refractory dryout schedules, provided by all refractory manufacturers with their products, are difficult to apply to refractory used on a steamgenerating boiler These The cement plant burns scrap tires as fuel in kilns The use of whole scrap tires as kiln fuel is possible for some design of kilns The advantage is no shredding cost compared to tire chips Tire Derived Fuel in Pulp Paper Mills Pulp paper mills have large boilersTire Derived Fuel in cement, pulp paper, power and boilerOnly by understanding all aspects pertaining to the design and installation of the refractory material can one find the root cause of the failure and help eliminate future failures A refractory failure is the number one cause of boiler inefficiency and a major contributor to boiler Understanding Refractory Failure—A New Perspective
