Webster Combustion Technology LLC says it offers custom engineering with its industrial boiler burner, the model FDR(X), to optimize performance in power plant applications. With a firing range of 15,000 to 200,000 MBH, Webster’s FDR(X) Forced Draft Register burner is a highly efficient combustion system that combines a windbox, air register, ignition assembly, fuel train, flame safety control, combustion control, flue gas recirculation (FGR) system, and a forced draft blower, all assembled into one complete packaged unit.

To ensure optimal performance and efficiency, Webster’s engineering team employs computational fluid dynamic (CFD) modeling to predict product performance or adjust product design prior to burner installation. Additionally, to reduce downtime, the design of Webster's FDR(X) burners allows for adjustment of the primary air register setting from the outside of the burner, without shutting down, pulling the burner, or accessing the inside of the windbox, thus enabling precise flame length, shaping, and adjustment during operation.

Webster’s FDR(X) burners are available in single or multifuel models, and can operate on natural gas, LP, coke oven, refinery and low Btu gases, as well as fuel oils ranging from diesel fuel to heavy viscous fuels such as No. 6 oil, on up to asphalt and tail oils.

FDR(X) units are designed for low combustion air velocities, permitting balanced air distribution to the burner. Fuel piping trains and operating components are mounted on the windbox and pre-wired to the central control panel. The addition of FGR allows for most applications to achieve less than 30ppm NOx emissions.
