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.
