Designed and constructed by Gilbert Associates, Inc., of Read ing Pa, Titus is expected to be in capacity operation ly next year. Steam for each of the two 80,000-kw turbine^generators now in service, and for the third, soon into service, is supplied by a Combustion fngineering-Superheatcr Boiler at 1450 pei and gOP<3 P, reheated to 1000 P. These C-E Boilers are PjdverUed coal fired. Each Combustion Boiler has been designod to incorporate two Ljungstrom Air Preheaters which preheat incoming combustion air to 600 F, and cool exit gases to 280 P. At Titus, os at scores of power plant installations across the country, once again the broad general acceptance of the Ljungstrom Air Preheater for top efficiency stenm generating units is demonstrated. Ljungstroms placed in service or on order eince 1945 alone -- selected by every major boiler manu facturer, consulting engineer and utility -- are serv ing boilers with an aggregate capacity of over 285,000,000 pounds of steam per hour. |Air Preheater Corporation lost 42nd St., New Virk 17, N.
