The `B‘ Station Boiler layout was similar to Willington `A’ but both Babcock Reheat Boilers were completely outdoors with the exception of the Mill bay and a small cover around the end of the Boiler Drum. Both FD fan suctions were outside and required braziers to stop the air intakes from freezing up in winter. Even the Deaerators were outside and great care had to be taken in winter months to ensure that all the required precautions were in place to prevent frost damage and loss of vital instrumentation. Each Boiler had 8 Babock & Wilcox Type `E’ ball mills and the burners were conventional front wall fired. The size of the mill bay was also kept to a minimum by having the mills belt driven which allowed the motors to be set alongside each mill in a more compact manner.
