 Each of the stations featured large boiler houses , turbine halls , switch houses , flue gas cleaning plant and a pair of concrete chimneys . Blyth A 's chimneys stood at 140 metres ( 460 ft ) and Blyth B 's chimneys stood at 170 metres ( 560 ft ) , major landmarks on the South East Northumberland skyline . Each chimney weighed approximately 17 @,@ 000 tonnes ( 16 @,@ 730 long tons ; 18 @,@ 740 short tons ) . The prominence and large scale of the buildings in the surrounding flat rural area , was the subject of much contemporary architectural debate . Blyth A 's turbine hall was 120 metres ( 390 ft ) long by 37 metres ( 121 ft ) wide , and 26 metres ( 85 ft ) high . It was built from a reinforced concrete frame , clad with brickwork . It housed four 120 MW Metropolitan @-@ Vickers 3 @,@ 000 rpm turbo generators , each connected to a Babcock & Wilcox boiler , situated in the boiler house . Each boiler and generator set operated independently , with no connections to other sets . Coal fed into the boilers was pulverised by a Babcock & Wilcox pulveriser , fed by a coal bunker with a capacity of 2 @,@ 000 tonnes ( 1 @,@ 968 long tons ; 2 @,@ 205 short tons ) . Each pulveriser was capable of pulverising 15 tonnes ( 14 @.@ 76 long tons ; 16 @.@ 53 short tons ) of coal an hour , sufficient to keep its associated boiler at full output . The boiler house was 110 metres ( 360 ft ) long by 28 metres ( 92 ft ) wide and 48 metres ( 157 ft ) high . It was built from a steel frame with aluminium cladding . The A station 's design was an unusual mix of styles ; the brick construction of the turbine hall was a style used more often in the 1950s , while the aluminium and glass cladding boiler house was a construction style used more in the 1960s . The A Station housed two control rooms , each of which served two generating sets and contained the controls to operate boilers , turbo generators and auxiliary plant . The A Station 's switchgear was provided by A. Reyrolle & Company .
