Combustion

Team burners are specifically designed to deliver the amount of heat required, commonly from 1 to 10 million BTUs (nozzle size from 2 to 8 inches, 51 to 203 mm). Team also has burners that will deliver an astonishing 100 million BTUs. In addition to multiple safety interlocks and redundancies, these systems feature a turndown ratio of 100:1, which allows Team to vary heat output from candle intensity to full blast in increments as small as 1°F/hour. Output from 20HP blowers varies from 500 CFH to 168,000 CFH to ensure that heat is distributed evenly regardless of a vessel’s geometry.

Team’s Combustion Heat Treating method may be used in a variety of applications including:

Post-weld Heat Treatment

Carefully controlled post-weld heat treatment (PWHT) is a crucial step in maximizing the life of your process equipment. PWHT tempers the metal and reduces tensile stresses, minimizing the risk of brittle fracture, stress and corrosion cracking and metal fatigue. This is especially important for equipment used in harsh service environments. Team engineers ensure the structural integrity of the vessel or unit during treatment, and the company’s advanced PLC and wireless control technology achieves the precise control needed to get the maximum benefit from the treatment.

Refractory Dry Out

The secret to long refractory life is a professional Dry out using Team’s high-velocity combustion systems to ensure that every inch of your refractory is heated under control as tight as 1°/hour. Team’s dry outs (1) are designed to completely remove both free and chemically held water to minimize spalling and cracking, (2) prevent formation of thermal stresses that could weaken the refractory, (3) minimize the potential for slip plane and (4) assure cross-sectional ceramic bonding for exceptional refractory campaign life. Team also performs controlled heat-ups and shutdowns that can further extend refractory life.

Space Heating

Team’s Turbo Hot Air Blower systems improve the quality and wear of coatings and linings by controlling the temperature at the surface during all phases of preparation, application and curing. Clean electric heat leaves no residues.

Coating and Lining Cures

Forced curing quickly and thoroughly dries coatings and linings of baked phenolics and epoxies to improve quality and wear, and minimize the need for reapplication. The controlled and uniform heat distribution of a Team high-velocity combustion cure eliminates hot spots and ensures conformance to the manufacturer’s recommended heat schedule. Plus, you get online fast because forced curing does in hours what nature takes days to do.

Process Startup

It is well known that process heaters are designed for a small range of temperatures close to operating temperatures – not ideal during a start-up. Team’s high-velocity combustion systems feature exceptional turndown ratios (100:1), so they can be programmed to increase from candle-heat to process heat in tightly controlled increments. It is the best way to minimize thermal stress and ensure long run-times in cyclone boilers, CFBs, steel mills, glass plants and other process applications.
