Boiler Offers Superior Combustion Along With Extended Surface Tubes
CBEX Dryback Elite achieves 3 percent O2 across its 10:1 turndown range. The standard package offers 30 ppm NOX with less 10 ppm CO. The boiler is generally 20 percent smaller than other firetube models and heats up faster, according to the manufacturer. Its dryback construction offers ready access to all parts of the boiler for ease of maintenance. Utilizing the company’s EX technology, the boiler reportedly offers superior combustion along with extended surface tubes that transfer more heat than traditional tubes. The boiler has a larger furnace and simplified design for reduced stresses within the vessel. The company’s engineers used advanced computational fluid dynamics (CFD) to optimize the integration of core competencies, including burner, controls and heat recovery. CFD modeling also helps reduce thermal gradients and stresses in the system, ensuring a long pressure vessel life.
