Lignite, or brown coal, is a soft brown combustible sedimentary rock formed from naturally compressed peat. It is considered the lowest rank of coal due to its relatively low heat content. It has a carbon content around 60–70 percent. Very beneficial use of lignite is in cultivation and distribution of biological control microbes that suppress plant disease causing microbes. The carbon ...

· Particle size and shape distribution can be measured in great detail by dynamic image analysis (DIA). The narrow dispersion of repeated experiment results indies that the particle size distribution can be obtained with high reliability. Particle size distribution can be better fitted to RosinRammler equation than GaudinSchuhmann distribution and the .

Closely size graded lignite particles were pyrolysed at 808°C in a laminar flow furnace for times up to 1 s following heating up at 8 x 103'C/s. Following pyrolysis, the chars were rapidly cooled at about 3 x 104"C/s. Weight losses were measured as a function of pyrolysis time. The following measure ments were made on the chars: (1) nitrogen and carbon dioxide specific surface areas ...

The results indie that particle sizes of mine coal dust in intake airways are finer than those measured in the 1920's. The significance of these finer coal dust sizes is discussed relevant to the amount of rock dust required to prevent coal dust explosions.
