Process. Coal is transported to the coal bin by use of a conveyer from the coal stock piles or rail-car unloading stations. From the coal bin, the coal is fed into the coal pulverizer and dried using ~300° F air .
Insert the coal sampling probe into the dustless connector, open the ball valve and push the probe all the way until it hits the back wall of the burner line. Using a paint marker make a small mark on the
The SAS Line Blank Isolation Valve is an economical and effective way to isolate a coal pipe. Constructed out of heavy-duty A-36 steel for a long service free life. The SAS Line Blank is available in a variety of arrangements, including butt-weld, victaulic, flanged, and standard attachment styles. It is also available in a full or half penetration design.
Raw coal enters the top of the pulverizer through the raw coal feed pipe. The raw coal is then pulverized between the roll and rotating ring. Hot air is forced in through the bottom of the pulverizing chamber to remove unwanted moisture and transport the coal dust up through the top of the pulverizer and out the exhaust pipe directly to the burner.
