What is the rated output, economical continuous output and maximum continuous output of a circulating fluidized bed boiler?

　　Boiler rated load (BRL), also known as rated evaporation capacity, is the evaporation capacity of a circulating fluidized bed boiler at rated steam parameters, rated feed water temperature, using design fuel, and guaranteed boiler design efficiency.

　　The economical continuous rating (ECR) of the boiler, also known as the economical continuous evaporative capacity, is the evaporative capacity of the circulating fluidized bed boiler at the rated steam parameters, rated feed water temperature, and designed fuel to be able to operate safely and continuously with the highest boiler efficiency. .

　　The maximum continuous output of the boiler (boiler maximum continuous rating, BMCR), also known as the maximum continuous evaporation of the boiler, is the capacity of the circulating fluidized bed boiler at the rated steam (including reheater inlet steam) parameters, the rated feed water temperature, and the designed fuel in safe continuous operation. Generally, it corresponds to the maximum continuous evaporation under the condition of whole open (VWO) of the steam turbine governing valve.
