Abstract
Pulverized coal combustion has been used since 1920s when it was first adopted in a U.S. boiler, and is the most common selection for high capacities.
Japan, which is highly dependent to imported oil, is now rapidly being switched to coal.
Coal characteristics greatly influence on coal-burning and steam-generating equip-ment design and environmental pollution control. Coal has remarkably broad properties. Therfore, coal to be used should be tested or analized beforehand with regard to grindability, abrasiveness of coal and ash, combustion characteristics, ash slagging and fouling, pollutant emission such as dust, SOχ and NOχ, and so forth.
This paper primarily describes influence of coal properties on boilers, advanced denitrification technologies and combustion test facility. It also refers to coal dust explosion and safety.
