Efficient boiler operations involve correct operation and maintenance procedures that become even more important when large quantities of steam are generated and consumed. Food processing plants utilizing steam for can sterilization, retort cooking, pressurized cleaning, or other direct heating purposes, require a constant supply of live steam and thus a continuous supply of water to replenish water lost as steam. Improper water quality can tremendously reduce boiler efficiency because the impurities cause scale to be deposited on the heating surface; for example, a quarter-inch scale deposit increases fuel consumption by 25 percent (Fig. 1). Boiler efficiency is also reduced, and energy wasted, when fuel combustion is not adequately controlled.22 pagesapplication/pdfen-USVirginia Cooperative Extension materials are available for public use, re-print, or citation without further permission, provided the use includes credit to the author and to Virginia Cooperative Extension, Virginia Tech, and Virginia State University.LD5655 .A762Food processing plants -- Equipment and suppliesBoilersExtension publication6521398
