DFV Packaged Natural Gas Replacement System
DFV propane-air mixing systems from Algas-SDI are self contained units providing a mixture of LP-gas vapor and air which can replace natural gas. These compact systems are available in a variety of sizes ranging from 2.5 – 42 million BTU/Hr at delivery pressures from 5 to 12 psig atmospherically. DFV systems use the Algas-SDI Direct Fired vaporizers and the Algas-SDI atmospheric venturi system packaged together with an ASME constructed accumulator tank. The gas is mixed with air in the venturi and stored in the accumulator tank to provide uninterrupted flow of mixed gas from full flow to zero flow, automatically.
A liquid pump such as the Algas-SDI STABILAIRE pump system may be required to provide sufficient gas pressure for the mixing process.
