Phoenix VH Direct Fired Burner

Phoenix VH Direct Fired Burners feature rugged dependability.

When you need rugged dependability, Phoenix Velocity Heat (VH) has you covered up to 2,000,000 BTU/hr.

Typical applications for the VH burners are batch and continuous furnaces for heat treating, thermal oxidizers, non-ferrous melting furnaces, and many more.

VH direct fired burners are made to last, with rugged dependability and reliability built in.

Integrated gas and air orifices simplify burner piping, set-up and adjustment. 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.

Velocity Heat


Highest velocity fame — The VH produces an intense stream of hot gases to thoroughly penetrate the load and deliver precise temperature uniformity for consistent product quality and system efficiency.

Large turndown combined with high excess air — A wide turndown range with high excess air means VH delivers high velocity benefits and efficiencies across its operating range.

Customization with packaged convenience — All VH components have been pre-engineered to come together to meet your specific requirements. You choose the capacity, combustor outlet velocity, fuel type, and flame sensing components you need to do the job.

Unparalleled fuel and control convenience — The VH offers the convenience of multi-fuel capability with no nozzle change. Plus, you can use any control methodology; pulse firing, excess air or on-ratio.
