COAL-FIRED BOILERS FOR THE 1980'S. Since 1973, greater emphasis has been placed on the operating costs of vessels, particularly fuel costs. The rising prices of fuel oils have caused significant re-evaluation of the horse-power required for a given vessel. The availability of specific types and qualities of fuels is also of significant concern.
Boiler furnace design will depend more on fuel characteristics, and further heat transfer surface sizing will depend on furnace outlet temperature. Furnace Size Varies for Gas, Oil and Coal Firing - Furnace sizing is a very important for a successful boiler design. The variation in boiler furnace size can upset the performance drastically. Oil and gas fired units have more uniform sizes, but the coal fired units have large variation.
