The operation of steam boilers beyond their Maximum Continuous Rated (MCR) capacity has long been an issue of heated discussion. For many years, boiler manufacturers have rated their equipment to have a specific MCR on a continuous operating basis with a two- to four-hour peak rating, often times at 110 percent of MCR.Learn More
Fuel for boilers. The three most common types of fuel used in steam boilers, are coal, oil, and gas. However, industrial or commercial waste is also used in certain boilers, along with electricity for electrode boilers. Coal. Coal is the generic term given to a family of solid fuels with a high carbon content.Learn More
