SWA Coal - ProControl
ProControl is an automated control system that incorporates the K-System with additional functionality to provide coal terminal
facility operators with critical information regarding the status of the weather
instruments, water spray equipment, expected changes in weather, and status of coal
handling equipment. A version of ProControl known as ProControl Plus incorporates dust
monitoring instrumentation.
The ProControl system provides the following functions:
 | Monitors the local weather and computes the drying potential
for coal pile surfaces. |
| Uses 12 hour weather forecasts to schedule special
treatments such as manual application of chemical tarps, overspraying with water prior to
a freeze, or tying down of equipment in anticipation of a major storm.
|
| Automatically activates a network of water sprays for a
prescribed period of time. |
| Performs end-of-day calculations of estimated coal
contributions to Total Suspended Particulate (TSP) at specified monitoring sites.
|
| Prepares reports required by regulatory agencies.
|
| Issues visual and audible alarms for pre-set conditions.
|
| Issues warnings of impending conditions that may compromise
the effectiveness of the water sprays or the safety of facility personnel.
|
| Archives data and operator comments for future reference and
review by regulatory agencies. |
ProControl Plus
While the basic ProControl system does not use any inputs
from dust monitoring instrumentation, facilities often find the value of timely feedback
on the performance of their dust control system critical to the success of a zero
tolerance operation. Simpson Weather offers various monitoring systems including the PLACEM, Real-Time Aerosol Monitors, and TSP and PM10
hi-vol monitors.
