Abstract:
Combustion capability of coal was tested in the layer combustion boiler to find out the rules of coal's metamorphosed degree and granularity affect on the soot letting concentration,ignition time,burn out time,blaze length and carbon quantity in ash.These rules can provide theoretic evidences for decrease imperceptibility granule letting.And that were beneficial to cleaning and high efficiency burning for different metamorphosed degree coal.
Key Words: metamorphosed degree;granularity;soot concentration;ignition time
