Fives launches trailblazing new product : North American EcoFornax™ SLEx
Fives has formally released its newest , patented , low-NOx burner solution for process heating and oxidation applications . The North American EcoFornax™ SLEx incorporates innovative air / fuel mixing technology , engineered to deliver a stable , compact , medium velocity flame with low-NOx emissions . The single air and gas connections are designed to make burner installation and tuning easy . As the industry drives towards more environmentally conscious processes , Fives is ready to provide cutting-edge emissions reduction technology — reaching less than 30 ppm NOx emissions with this burner alone . During testing , the burner was applauded for its seven burner sizes , covering a large range of capacities that extend from 0.6 to 18.6 MMBtu / h HHV , operating at nominal 40 % excess air . Stephan Paech , President and CEO of Fives North American Combustion states : “ Emission reductions is one of our key drivers and this burner was extensively tested in our Cleveland laboratory to exceed the technological needs of our customers .” At design capacity , the burners can operate across a wide ratio range from 20 % excess fuel to 90 % excess air — with an even more expansive range at lower capacities . Its versatility and compatibility with hard refractory or fiber wall lined furnaces , makes the EcoFornax™ SLEx the simple and sustainable solution for process heating systems .
Stainless steel condenser shell tube heat exchanger
The stainless steel condenser shell tube heat exchanger is made of rolled plate metal or pipe . The most common material for these components is steel , but other metals can be specified for hightemperature , corrosion-resistant applications . A condenser shell heat exchanger is designed to maintain a low internal pressure while providing optimum thermal conductivity . Generally , the tubes are made of carbon steel or stainless steel , but they may be made from non-ferrous metals such as Inconel . Fluoropolymers are used for tubing material , since they are extremely durable and are highly resistant to extreme temperatures . However , if a tube material is not sufficiently durable or has poor thermal conductivity , it may cause cross-contamination of fluid or loss of pressure . A condenser shell heat exchanger is a type of heat exchanger where the tubes and shell are connected by a flange . This flange is not usually in direct contact with the shell , but is connected indirectly to the shell by two flanges . It can be removed for cleaning or for inspection . One advantage of this design is that it allows for counter-current flow . Condenser shell tube boxes are typically easy to maintain and service . They are available in different shell diameters . Some models feature floating tube bundles , which means that the tube plates are not welded to the outer shell . The tubes can be easily removed from the shell and replaced without affecting the function of the condenser . Some models have floating tubes , which make them easier to maintain and service .
