Following the rebuilding of some of the original chain grate coal fired boilers in the A station as oil fired units the needed extra steam capacity required for the 20,000 kW unit was supplied from the B station extra boiler capacity via a steam line several hundred feet in length.
The pressure step down valves were located at the B station [1] This site still features some original buildings, although most of these are stripped.
There was a building marked as a "transformer bay" in site plans, which housed a small control room until recently.
This building is also referred to as Agecroft A Substation [5] Cooling water was obtained from the River Irwell.
[4] The B station had four International Combustion Limited pulverised coal boilers rated at 35,000 lb/hr, steam conditions were 620 psi and a super-heater temperature of 538 °C with reheat to 538 °C.
[4] The B station had two hyperbolic Mouchel concrete cooling towers each rated for 3.08 million gallons per hour.
[7] The turbines were supplied with steam from two 860,000 lb/hr (108.4 kg/s) International Combustion Limited boilers operating at 1500 psi and 1000 °F (103.4 bar and 538 °C).
It was purchased by the Museum of Science and Industry in Manchester in a dismantled state in 2008, where it underwent a 3-year restoration costing £120,000.
Agecroft Colliery was closed in March 1991 and the closure of the power station was announced in November 1992.
