摘要： A method and system for controlling and providing guidance in reducing the level of NO.sub.x emissions based on controllable combustion parameters and model calculations while maintaining satisfactory plant performance and not causing other harmful consequences to the furnace. To implement such a system, boiler control values of flow, pressure, temperature, valve and damper positions in addition to emission sensors for data associated with the production of NO.sub.x, O.sub.2, CO, unburned carbon and fuel. This information is received from standard sensors located throughout a boiler which are connected either to a distributed control system (DCS), or another data acquisition system which is time coordinated with the DCS. The DCS passes this information to a computing device which then processes the information by model based optimization simulation programs, also referred to as the NO.sub.x Emissions Advisor. The presentation of recommendations to the operator consists of a series of graphic displays hierarchically arranged to present the operator with a simple summary that has available more detail support displays at lower levels. The NO.sub.x emissions automation system transmits the recommended positions to the controlling devices including furnace air dampers and coal feeders.

摘要： A method and system for controlling and providing guidance in sootblowing based on continuous plant monitoring and model calculations. The continuous monitoring of plant conditions is through a plant distributed control system (DCS) which communicates with a computer. The conventional measurements of a DCS such as flow, pressure and temperature and sootblower status data are input into the computer. These valves are validated for accuracy. To predict the effects of fouling a plant model is utilized. The model predicts the rate and effect of fouling on energy distribution in the boiler. The model then predicts the effect that sootblowing of each section will have on the boiler performance. A comparison of the predicted and observed effects are used to update the fouling model and maintain consistency with the actual performance of the boiler. This information is presented to the boiler operator to assist in enhancing the boiler efficiency and maintain steam temperatures within established control ranges.

摘要： In a power plant, a deaerator is a feedwater conditioning device which provides direct contact feedwater heating as well as providing for oxygen removal to inhibit corrosion. Under some conditions, called transients, rapid depressurization could occur in the deaerator which might result in damage to internal deaerator parts. By limiting the condensate flow into the deaerator, the rate of depressurization can be reduced. A control system is described which will react to a reduction in turbine load by reducing the flow of condensate to the deaerator.

摘要： A power plant may include a steam generator and a steam turbine wherein the steam generator provides steam to the turbine for driving the turbine and exhausted steam from the turbine is condensed in the turbine condenser to be pumped back to the steam generator as feedwater. In order to maintain minimum feedwater pump flows and to provide an alternative flow path should the steam generator require less than the available feedwater flow, a recirculation loop is provided for returning a portion of the feedwater to the turbine condenser. According to the present invention, this return flow to the condenser may be used for deaeration of condensate and for the attemperation of bypass steam.
