ABSTRACT:
The improved gas flow rate control regulator valve of the present invention maintains an optimum precombustion air to gas mass ratio for a wide range of air and gas flows within the combustion chamber of a furnace for efficient burning. The regulator valve of the present invention includes at least one piston diaphragm chamber containing a control piston for equalizing the pressure of the gas effluent with that of the precombustion air in a first preferred embodiment. In a second preferred embodiment, a bottom control piston chamber containing a piston of a size greater than the size of the top control piston is provided such that amplifier means for increasing the gas pressure are provided for application where the gas pressure to the combustion chamber must be greater than the pressure of the available precombustion air. In a third preferred embodiment, the present invention functions as a mass flow regulator suitable for use in connection with two pneumatic impulse lines, which are disposed on opposite sides of a restrictor disposed within the line in order to detect the pressure differential across the restrictor.
