The current generation R&V burner is a multiple fuel burner for gaseous and liquid fuels, specifically designed for high performance long-term free-of-maintenance operation. The patented burner design incorporates a unique low-pressure air system to atomize liquid fuels and to achieve intrinsic (inherent) gas or oil flame stability (virtually irrespective of combustion airflow conditions such as velocity, pressure drop, temperature, etc.).

Basic design and performance features of the R&V burner may be summarized as follows:

• Dual / multiple fuel firing capability
• Parallel air flow design (no registers required)
• Low draught loss
• Intrinsic flame stability
• Low fuel pressures
• Liquid fuels atomized by low pressure atomizing air (no atomizing steam required)
• High turndown capability
• Very low excess air firing
• Low NOx emissions
