• Heat Treat • Process Heat • Stress Relieving • Operating temperatures between • Improved cycle time, uniformity, • Precise control • Minimized capital costs • Minimized down time • Modulating or Pulse Firing • Laboratory verification of designs • Maximum heat transfer and burner service network The Low Temperature Regenerative (LTR ) heat recovery system was developed for continuous or batch furnaces with a variety of burner configurations, control zones and operating temperatures up to approximately 1600°F (871°C), where maximum heat transfer and burner efficiency is required. Today, the most common device for energy savings in process/heat applications is a metallic recuperator. The LTR™ system is a more thermally efficient alternative to using a recuperator. Bloom Engineering's coupled Regenerative burner technology has proven successful for more than two decades. Combine this with demonstrated LTR™ field installation results and you have an exciting new cost-saving solution.

ner designs include a recuperator that is integral preheats the incoming combustion air In comparison to this technology, the more efficient centrally located n operate with more extensive burner capacities and is tly limited by maximum temperatures like an all-metal Self-Recuperative burner. LTR™ system RELIABILITY & FUEL SAVINGS The purpose of the LTR™ System is to provide heat recovery in low temperature processes at a level that produces a payback suitable for the In general, the devices curently available for heat recovery in these process are metallic recuperators. Typically, these types...

the need for large refractory lined flue and stack system • Minimized C02 emissions due to increased fuel efficiency The system utilizes a pair of regenerators and a set of cycle valves switching between 2 cycles. During the 1st cycle, one regenerator provides preheated combustion air to multiple burners while the other regenerator is storing heat. In the 2nd cycle, the regenerators switch functions. Essentially, the LTR™ system can take the place of a conventional recuperator. Small systems using 1 or 2 burners are not candidates for LTR™. Cost wise it is easier to apply standard regenerators...

Bloom Engineering Company, Inc. 5460 Horning Road Pittsburgh, PA 15236 Burner Selection number of Bloom Low to Ultra designed to handle high air temperatures including: Operating Temperature Range Fuel Savings provide an average air preheat Subsequent Fuel Savings = 10 -11% 2) The LTR™ system is designed to provide a significantly greater air incoming flue gas temperature. Subsequent Fuel Savings = 19 - 20% 3) Doubling the fuel savings can make a heat recovery project more attractive, but there are other major considerations including: A Cost and time to make B Operating hours per year BENEFITS...
