Fan A fan can be considered a mechanical device that moves a volume of fluid such as air, gas, or vapor through a pressure driven flow. Large capacity fan units typically consist of a bladed, rotating impeller enclosed in a stationary casing. The … Webbpower to preclude the need for a plant trip and associated transient. In another event, the operators quickly diagnosed the cause of and terminated a turbine runback.

Load-following power plant - Wikipedia
The final phase of tuning is runback testing. Turbine following is a nice safe place to retreat to when the operator has the time to take action. However, what happens when there is no time to react? For these situations two control strategies are used: runbacks and rundowns. A runback is an action taken on a loss of … Visa mer Boiler tuning is something of a balancing act. Feedwater enters the boiler through a series of low- and high-pressure steam heaters into the drum. The water then journeys through the water walls of the furnace and absorbs … Visa mer Coordinated front-end control was developed in the late 1970s and early 1980s to answer a long-standing controls problem. For many years, the turbine master controlled megawatt production and the boiler master … Visa mer The tuning process can’t be rushed and does take some time to get right. Here is an example. Recently, I walked into the control room of an 800-MW unit just as the operators made a load change. As you can see, the response of … Visa mer Unit load demand is the high- and low-limited and rate-limited version of the unit master demand. The operator enters in his target megawatt load into the DCS. There are high and low limits … Visa mer WebbStep #1: The condensate storage tank is filled with demineralized water.
