Control system for flue gas conditioning.

摘要

Flow rate by volume for adding a conditioning agent flue gas, such as sulfur trioxide, stable KEEPING THE DERIVATIVE OF POWER Electrostatic Precipitator RESPECT INDEX FLOW WITHIN A LIMIT OF OPERATION PRESELECTED. POWER derivative with respect to time precipitator AND DERIVATIVE flow index are measured with respect to time, and then DERIVATIVES ARE DIVIDED TO DETERMINE THE DERIVATIVE precipitator POWER FLOW WITH RESPECT TO THE INDEX. This calculated value is compared with an operating limit PRESELECTED. IF THE ESTIMATED VALUE IS GREATER THAN THE LIMIT OF OPERATION preselected INDEX FLOW INCREASES conditioning agent. If the value calculated is less than the limit OPERATION PRESELECTED, the rate of flow is reduced, UNTIL REACHES derived value calculated within the limit fixed state OPERATIONAL.
