Exhauster inlet venturi Sure Alloy Steel Corporation
An inlet venturi for coal-side exhauster fan structure used to deliver pulverized coal to a combustion chamber. Generally, the inlet venturi has an axial length comparable to that of the exhauster fan inlet, resulting in a shallow, smooth transition angle from the venturi to whizzer ring or similar structure for guiding the coal flow into the center of the fan assembly.Employing CFD analysis, Robinson Fans recently developed an innovative coal mill exhauster with significant improvements over the traditional “whizzer wheel” design. Used to move pulverized coal to burners in the power, cement and lime industries, Robinson’s new backward-curve design showed an improvement of more than 20 ROBINSON FANS, INC..

Application ABB Pressure measurement Diaflex
Many coal-fired power plants measure various pressures associated with their coal pulverizing mills. The red dots in the figure at right shows the typical locations for these measurements for a Raymond Bowl type mill: the pulverizing mill section the ductwork from the classifier carrying coal fines to the . exhauster, andThe exhauster supplies pulverized coal to three riffle type distributors. The riffle distri- bution system on each mill supplies pulverized coal to eight coal nozzles, a total of 32 coal nozzles for the entire boiler. The exhauster discharge pressure is approximately 10 to 12" w.c. under full load operation.Pulverizer Fineness and Capacity Enhancements at

Pulverized coal preparation system is one of main backup system of fuel-burning power plant, because barrel-shaped steel ball mill is the strongest to the adaptability of coal, is domestic most widely used a kind of coal pulverizer.Coal pulverizer is the key equipment of pulverized coal preparation system, and can it normally move and whether operate in The suction mill draws hot primary air and entrained coal from the pulverizer under negative pressure by an exhauster located on the outlet side of the pulverizer. The exhauster at the outlet side of the pulverizer is subject to severe erosion from the pulverized coal/air mixture. Some mills are a combination of the pressurized/suction mill.Pulverizer Failure Cause Analysis: FP-1226 Research Project
