Replacements and upgrades for OEM power station equipment. R-V Industries haves decades of experience serving the power generation industry and helping customers maximize their efficiency by upgrading coal delivery systems, nozzles patented nozzle tips, resized windboxes, and replacements. Our expertise has helped hundreds of power stations across the U.S. and worldwide increase the longevity of their equipment and realize meaningful returns on investment.
Boiler Equipment Upgrades
Coal and oil nozzle tips in all grades of materials. Designs include one-piece, two-piece, fixed offset air, adjustable offset air and overfire air, including the replacement of low NOx nozzle tips. Patented Thermalguard design increases the effective service life of the nozzle.
R-V Industries offers air tips in all grades of materials. Designs include one-piece, two-piece, fixed offset air, adjustable offset air and overfire air.
R-V Industries designs cast and ceramic-lined stationary coal nozzles with a variety of weld overlay protection options for increased equipment longevity.
Stationary coal nozzles, lined with chromium carbide, are revolutionizing the power generation industry by significantly increasing the lifespan when compared to cast nozzles. In addition, repairing the chromium carbide nozzles with weld overlay allows for on-site spot repair, when ceramic-lined stationary nozzles require complete re-lining if one ceramic block fails.
R-V Industries designs and manufactures complete windbox assemblies for corner-fired furnaces, in addition to providing a complete line of corner-fired windbox equipment. Our experience includes the replacement of existing windboxes, windboxes for new installations, and overfire-air windbox assemblies for reducing NOx emissions.
In addition to complete new windbox assemblies, R-V offers a full complement of damper and tilt mechanism components. Our self-aligning graphite damper bearing upgrade will enhance air regulation, resulting in improved efficiency and effective NOx control. Our modular tilt mechanism replacement provides a cost-effective installation approach to upgrading your original tilt system hardware. We also offer an opposed-damper blade design to improve your airflow distribution and control.
With three design choices, R-V Industries’s riffle elements and adjustable riffle assemblies provide the custom quality you’ve come to rely on. R-V’s riffle elements are engineered to fit all existing primary, secondary, and tertiary housing sizes. Choose from the original equipment, coarse cut, or R-V’s mid-cut model to best suit your boiler’s needs.
R-V’s adjustable riffle assembly design was tested by EPRI and proven to redistribute coal flow from an 80% – 20% imbalance to a 50% – 50% balance without increasing pressure loss.
R-V has a full line of furnace doors, including direct replacements for the 4″ x 10″ observation door and the 15″ x 21″ elliptical door. Standard and custom sizes can be insulated with mineral wool or refractory or they can be cooled with water to meet your specific temperature requirement. All doors are available with seal boxes and tube panels as an option.

R-V Industries offers a replacement modular low NOx (LNx) air register that will fit over your existing low NOx coal nozzles. The low NOx register is also available as a complete plug-in low NOx coal burner assembly. R-V’s low NOx axial swirl assembly replaces dozens of radial vanes and associated bushings, shafts, and linkages. This simplicity assures long-term reliability.
Natural gas firing conversions are a great way to lower operating costs as a glut of affordable gas has become available in the US. We provide gas spud assemblies and compartment arrangements for fuel conversions.
R-V has manufactured fan spiders, whizzer discs, fan blades, and complete whizzer wheel assemblies since 1981. Our ceramic whizzer wheel assembly uses an aggressive ceramic design with vacuum-bonded blades furnished in ceramic or combined with tungsten carbide tips. Our fan spider has a unique one-piece ceramic-lined replaceable liner which is made complete with ceramic whizzer blades and a ceramic whizzer disc. Your individual design preferences may be incorporated into any of R-V’s whizzer wheel assemblies. We offer individual ceramic-lined components or complete whizzer wheel assemblies that are static balanced and ready for installation. We also offer a rebuild service for your high-efficiency fan wheels.
