Operation of a waste-heat boiler a glass-melting furnace  

GT V01 1960 204-208

A total fuel saving of nearly 7000 tons of coal has been achieved since the waste-heat boiler was installed at Pilkington Brothers (Queenborough) Limited, and taking all items into account, there has been a substantial  reduction in the cost of steam services to the works. The performance of the boiler on continuous service is  entirely satisfactory.
