     · Typically, the moisture content of subbituminous coals ranges from 15 to 30 percent, while that for lignites is between 25 and 40 percent, where both are expressed on a wet coal basis. High fuel moisture has several adverse impacts on the operation of a pulverized coal generating unit. High fuel moisture results in fuel handling problems, and it affects heat rate, mass rate (tonnage) of ...

    Pulverized Coal Pipe Testing and Balancing

    With wet coal, these tips often plug, adding to sample collection errors. Also, our probes can handle highcapacity fuel flow rates of up to 50,000 lb/hr per pipe and are virtually unpluggable. Our sampler is also designed with an internal orifice to measure the amount of air moving through the sampler. With the pressure drop through the sampler, this orifice is able to measure and control the ...
