Typical applications for the VH burners include batch and continuous furnaces for heat treating, thermal oxidizers, nonferrous melting furnaces, and many more. VH direct fired burners are made to last, built with rugged dependability and reliability in mind. Integrated gas and air orifices simplify burner piping, set-up and adjustment. The orientation of the integral air and gas inlets are adjustable in 90-degree increments to suit a variety of piping alternatives making installation, operation and maintenance simple and cost effective. The VH burners can be operated on-ratio and with fixed air control schemes. The built-in ignitor ensures reliable ignition of the VH burners across the entire operating range. High-temperature powder coated components and the stainless steel nozzle option assure that the burner will stand up to the demanding environments of industrial heat treat applications. All burner components are easily accessible making annual maintenance of the burner fast and easy. The VH burners are designed to be compatible with the Honeywell® (1) and Eclipse® (2) ThermJet burners and are a direct replacement for the TJ burners without any material impact on performance and other operational aspects of the process
