Makers of steel power and heating boilers COLUMBIA'S H.R.T.* OIL OR GAS FIRED BOILER & STEAM GENERATOR ASME CODE CONSTRUCTED-- Available for pressures of 15 to 150 psl. A complete, automatic power plant wherever steam, is used for pro cessing Horizontal Design for longer life: The complete submersion of tubes pro tects them from water line corrosion. Dry Steam Assured: Large steam space and greater liberation area vir tually eliminate waste producing water carryover.

Available in sizes ranging from minimum. Special refractory brick heats two to sixty horsepower. Designed for up to great intensity to complete the firing with gas, light or heavy oils. A combustion of previously unignited fuel special Columbia unit makes possible the inter-changeable use of gas or oil. Overfiring Permitted: Conservative rat ings plus large combustion volume per mit overfiring. This frequently elimi nates the need for additional boiler capacity, allows for plant expansion. particles. This complete combustion not only increases efficiency but makes for clean combustion. Soot accumulation on heating surfaces is minimized. Boiler tubes require less cleaning. Safety Assured: Two pass updraft design lowers direct loss and reduces possibility of furnace pressure, pulsation or exces High Steam Output: Columbia's h.r.t. sive combustion noises. boilers have an unusually large beating surface to produce more steam at higher efficiencies. More beat is converted into steam since it is proportioned to make maximum use of hot gases of combustion for the production of steam. Accessibility and easy Maintenance: Simplified construction provides easy front and back access to the single bank of tubes. Entire unit can be gotten to for inspection of boiler and chamber by removing the covers. ______________ SPECIFICATIONS AND DATA COLOMBIA HRT BOILERS FOR GAS.
