Description

The plant built in 1939 consists of 18 Simon-Carves underjet silica ovens on the site of an older battery. The ovens were rebuilt in 1955.

It carbonises 140,000 tons per annum (380 tons per day) of washed smalls from the adjacent Trimdon Grange Colliery. In order to obtain an economic throughput from a plant of this size the ovens are operated on a fast coking time (17 hours compared with 20 hours at Fishburn and Lambton). The furnace coke produced is small in size but crushed coke breeze is blended with the coal in order to maintain coke quality. There are landsale facilities and capacity for stocking and reclaiming 40,000 tons of coke, using mainly mobile equipment.

Water for cooling purposes and steam raising, is obtained from Trimdon Grange Colliery. The boilers are of the Lancashire type, fitted with mechanical stokers, gas burners and economisers.

3 million cubic feet of unpurified gas are supplied daily to the Northern Gas Board. The crude benzole produced is dealt with in a small refinery on the works along with benzole from other coking plants. Ammonia is recovered as conentrated liquor in a plant which is shortly to be renewed. For the ti being, effluents are pumped into a disused quarry.
