Most heat treatment processes require accurate control of the material temperature. With the advent of fast acting combustion burners and burner control systems it is easy to implement very responsive cascade control to the furnace.
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). We also have 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 our technicians 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.
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. Our 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 our high-velocity combustion systems to ensure that every inch of your refractory is heated under control as tight as 1°/hour. Our 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. We also perform controlled heat-ups and shutdowns that can further extend refractory life.
