Newcastle Steelworks Gasholders
|
|
The Coke Ovens and Blast Furnace Gas Holders once dominated the Steelworks landscape, which could be seen from most Newcastle Suburbs.
The larger Blast Furnace Gas Holder was commissioned in 1938 and held approximately 80,000 cubic meters of gas from the Blast Furnace.
It was 75m high and 42m in diameter, which consisted of a 22-sided polygon made of specially pressed steel plates, a steel bottom and self-supporting roof. Inside the shell was a piston, which floated on the gas stored underneath. The piston was weighted with hundreds of concrete blocks, the number of which determined the operating pressure of the gas.
The smaller Coke Ovens Gas Holder was commissioned in 1937 and held approximately 56,000 cubic meters of gas from the Coke Ovens.
It was 63m high and 38m in diameter, which consisted of a 20-sided polygon.
The gas holders played a vital role in the energy balance on the Works and without the holders the Coke Ovens and Blast Furnace gas would be flared to atmosphere to control the pressure.
