Aftermarket Spare Parts for Heat Recovery Equipment

Aftermarket Spare Parts for Heat Recovery Equipment

Since Thermal Transfer Corporation's recuperators and heat exchangers have no moving parts, they do not require the customer to maintain an extensive spare parts inventory. However, spare tubes, spare tube bundles, or complete spare units can be provided upon request. Because of the long delivery time typically required to fabricate a recuperator or heat exchanger, we recommend purchasing replacement units in advance so they will be on hand when needed.
 
A spare parts inventory should be maintained for Thermal Transfer Corporation's fired heaters and gas coolers since these products incorporate fans, pumps and electrical components. However, since each design is unique, a customized spare parts list is required for each application. Therefore, standardized spare parts lists are typically not available for our products.

Convection Recuperators

Convection Recuperators

Convection recuperators (also referred to as "flue" or "canal" recuperators) are tubular heat exchangers that utilize convection heat transfer to preheat combustion air or gas for the purpose of saving fuel. By recovering heat from the hot waste gas exiting a furnace and transferring it to the combustion air feeding the burners, fuel usage can be reduced by an average of twenty-five percent (25%), and in many cases, greater savings are realized. Waste gas temperatures entering convection recuperators are usually in the 1500°F to 2000°F range, and combustion air preheat temperatures are usually in the 800°F to 1200°F range.
 
For high temperature industrial furnaces, such as steel reheat furnaces, recuperators are valuable tools for increasing furnace efficiency. Up to sixty percent (60%) of the available energy in the fuel may be carried out of the furnace in the waste gas, therefore, heat recovery is essential for fuel conservation and economical operation. With fuel costs...

Fired Heaters

Fired Heaters

For over forty years, Thermal Transfer Corporation has supplied fired heaters for a wide range of industrial applications. Each is custom-made for the specific conditions involved, taking into account process and material temperatures, flow distributions, corrosion potential, plant space constraints and, of course, the degree of efficiency and reliability needed for optimal economic and safe service. Whether designed for atmospheric or high pressure, all of our indirect fired heaters utilize a two-step process: generating combustion gas, and subsequently heating the process fluid through a separate heat exchanger.
 
Featuring integrated control systems, Thermal Transfer Corporation heaters are furnished complete or as pre-assembled components ready for simple field assembly, installation and easy startup. The products of advanced manufacturing techniques and painstaking quality assurance, they also incorporate the industry's most sophisticated, state-of-the-art technology. Thermal Transfer...

westinghouse air brake technologies company Gas Coolers

Gas Coolers

Thermal Transfer Corporation gas coolers find the widest application in the area of environmental control, where hot dirty emissions from industrial processes must be cooled for entry into pollution control equipment. Most of our coolers employ ambient air as the cooling medium, although water-cooled units are furnished as well. A prime consideration in the design of all Thermal Transfer Corporation coolers is the necessity for keeping the heat transfer surfaces clean: arrangements are largely selected to allow continuous in situ cleaning utilizing soot blowers, shot or chain cleaning systems. Combined cleaning methods can be used for especially heavy carryover situations.
 
A typical gas cooler is designed with the hot waste gas flowing vertically down over the outside of horizontal tubes, while cooling air passes inside the tubes. A large volume of cooling air is usually provided by multiple vane axial or panel fans mounted on the side of the cooler. A complete system is normally supplied...

westinghouse air brake tech Radiation Recuperators

Radiation Recuperators

Radiation recuperators are high temperature heat exchangers that utilize radiation heat transfer to preheat combustion air or gas for the purpose of saving fuel. By recovering heat from the hot waste gas exiting a furnace and transferring it to the combustion air feeding the burners, fuel usage can be reduced by an average of thirty-five percent (35%), and in many cases, greater savings are realized. Waste gas temperatures entering radiation recuperators are usually in the 2000°F to 2500°F range, and combustion air preheat temperatures are usually in the 800°F to 1400°F range.
 
For very high temperature industrial furnaces, such as glass melting furnaces, recuperators are valuable tools for increasing furnace efficiency. Up to seventy-five percent (75%) of the available energy in the fuel may be carried out of the furnace in the waste gas, therefore, heat recovery is essential for fuel conservation and economical operation. With fuel costs rising, recuperation is certain to...
