    摘要： A carburetion system and method for adapting a low-Btu gas source with a low-Btu gas consumer. Pressure-based air-gas mixers geometrically appropriate for the carburetion system and method. The carburetion system comprises a low-Btu gas inlet, a gas outlet, a zero-pressure regulator, and at least one pressure-based air-gas mixer capable of maintaining a volumetric air to low-Btu gas ratio of no more than about 2:1. The method comprises diverting a low-Btu gas to a gas outlet when the gas consumer is off. The method further comprises, during operation of the consumer, diverting low-Btu gas to a zero-pressure regulator in order to balance low-Btu gas pressure with air pressure, passing low-Btu gas to at least one pressure-based air-gas mixer capable of maintaining a volumetric air to low-Btu gas ratio of no more than about 2:1, mixing the low-Btu gas with air in the at least one pressure-based air-gas mixer to form an air-gas mixture, and sending the air-gas mixture to the consumer. A venturi air-gas mixer comprising at least one venturi gas intake and at least one venturi air intake wherein the at least one venturi gas intake has a cross-sectional area at least equal to the cross-sectional area of the at least one venturi air intake whereby the venturi air-gas mixer is capable of maintaining a volumetric air-to-gas ratio of no more than about 1:1.
