✦ Synopsis

CHEMISTRY AND INDUSTRY can be stnrtcd up or shut down almost imnicdiately, and tlie amount of the fuel burnt altered within vcry wide limits by merely turning valves, nicans that the fluctuations in a gas supply can be followed and allowed for without difliculty and all thc gas utilised whilst maintaiiiing n steady steam output.

The most rcmarkable csainplc of this, of coursc, is the famous Ford plant at Rivcr Rouge, Dcnrborn, Detroit, which nornially burns 70 per ccnt. blastfurnace gas and 30 pcr cent. pulvcriscd coal on sonic of the largest watcr-tubc boilers in the world, with a normal evaporation of 220,000 Ib. of watcr (from and a t 312" F.) each per hour and 350,000 1b.cnicrgcncy overload. Owing to this great flexibility of pulveriscd fiicl firing ti volume of dirty blast-furnncc gas of 90-100 B.Th.U. per cb. ft. amounting to about 70 niillion cb. ft. per 24 houm, and of course greatly fluctuating in a ~n ~u n t , is being burnt at the highest cflicicncy. At tlic saiiie time also cokc-own gas, tar, oil, or pulvcrised coke are used whcn nccessary, and it is intcndcd crcntunlly to usc pulverised lowt empcra t urc f ucl .
