Abstract:
A method, system, and computer readable storage medium for managing powdered activated carbon (PAC) injections for controlling mercury emissions from coal-fired boilers. A mercury concentration value received from a mercury continuous emissions monitor is stored in the plant control system database. A PAC injection rate from an activated carbon injection system also is stored in the plant control system database. If the mercury concentration value is greater than the mercury setpoint, a signal is sent to the activated carbon injection system to increase PAC injection by a predetermined value. If the mercury concentration value is less than the mercury setpoint, a signal is sent to the activated carbon injection system to decrease PAC injection by a predetermined value.
