ALTERNATIVE-FUEL GAS ORIFICE HAVING PRINCIPAL-FUEL GAS ORIFICE TEMPERATURE PROFILE AND A HEATING, VENTILATION AND AIR CONDITIONING SYSTEM INCORPORATING THE SAME |
摘要 |
An alternative-fuel gas orifice, a gas furnace configured to employ the same and a method of designing a gas orifice. In one embodiment, the gas orifice includes: (1) a body having an aperture extending therethrough and including: (1a) a metering neck having a cross-sectional area such that a given flow rate of a gas is established when the gas is delivered to the gas orifice at a given alternative-fuel delivery pressure and (1b) a diffuser having a cross-sectional area larger than the cross-sectional area of the metering neck and a length such that the gas achieves a substantially laminar flow before exiting the diffuser.
