10/9/2015#0183;#32;Coal mill hot air inlet temperatures should never be more than 600 #176; F and the outlet temperature should not exceed 200#176;F on Raymond coal mills. If the flow of raw coal to the coal mill is interrupted for any reason (for example: plugging, failure of the coal feeder, etc.), the outlet temperature of the coal mill can quickly climb to dangerous levels.
NFPA requires coal mills to be good for 50 PSI. What Are Common Mistakes Seen In These Industries? Vincent described constructional explosion protection as the lastditch defence against explosion hazards. You will normally try to avoid the explosion in the first place. Most systems in the cement industry work with low oxygen levels.
Coal stockpiles and coal bunkers Coal is stored as a rule outdoors on a stockpile without protection against dampness and moisture. Coal bunkers, on the other hand, provide the means to store the fuel in a dry environment. Coal red power plants are often equipped with both storage options.
