I0WANK HI-TEST SERIES HT Two-Pass Portable Tubular Boiler for High Pressure Steam THE KEWANEE HI-TEST TUBULAR BOILER is now in production ready for immediate duty in any Steam usage for Power service or Industrial Process. HT-SERIES has been newly contrived to fit modern ways and means of manufacture. It is planned with due regard for easy handling. Even when performing under critically heavy loads this fusion-welded steam generator is found highly efficient, offering continued "economies in fuel year in year out. Characteristically portable, the KEWANEE HI-TEST TWO-PASS boiler is compact yet extra rugged, built in full conformity with A.S.M.E. Boiler Code. Fabrication by qualified welders using latest facil ities reflects a modem practice in streamline construction for high pressure. The metal casing is de signed for a refractory lined firebox or combus tion chamber, making it entirely self-contained. All fuels whether solid, liquid or gas. hand or mechanical fired from front, side or rear may be burned with eco* nomical results wherever high pressure live steam is consumed, even if the condensate is not returned to the Boiler. 2 To meet stringent requirements of the A.S.M.E. Code for high pressure power boilers careful selection, preparation and assembly of all plate material is mandatory. All joints are Fusion Welded by his- trained work men, X-Ray checked and test-specimen results recorded. Fusion Welded seams for the heavy flanged heads and tubular shell were adopted after thorough investiga tion and painstaking development of procedure con trolled by code and proved by exograph inspection. During the course of construction and after compiction each boiler is rigidly inspected by a qualified Inspector licensed by the National Board of Boiler and Pressure Vessel Inspectors to insure universal accept ability by any State or Municipality. Fusion Welded Joints are thoroughly annealed to in sure Relief of Locked-up Stresses by raising the tem perature of the bare Boiler and holding in a zone of 1200 F., then allowing to cool gradually. Our huge modern Recirculating-Type Stress Relieving Furnace, photo above, the only one of its size, insures a um/orrrnly of temperature of less than 100 variance throughout its entire interior. This procedure is iilallo important for absolute dependability, as well as ulti mate safety. 3 KEWAN HI-TEST Series HT Specifications-- BOILER NUMBER HORSEPOWER STEAM RADIATION--HANO FIRED -MECHANICALLY FIRED HEATING SURFACE GRATE AREA OR PLAN AREA FURNACE VOLUME FURNACE WIDTH LENGTH HEIGHT ABOVE GRATES CYLINDER DIAMETER FRONT REAR BOILER LENGTH OVERALL BOiLER HEIGHT FLOOR TO TOP OF SHELL WATER LINE HEIGHT STEAM SUPPLY SIZE BLOW-OFF SIZE FEEO WATER SIZE INJECTOR SUPPLY SIZE SAFETY VALVE BOILER OPENINGS NO -SIZE-- 125 LB VERIFY ALL SIZES - - 150 L8 BREECHING OIAMETER STACK DIAMETER STACK HEIGHT-HAND FIRED STACK HEIGHT-MECHANICALLY FIRED BREECHING OIAMETER.
