Gas burner control and ignition system for oilfield separators
First Claim
1. A gas burner control and ignition system for an oil and gas separator, the separator capable of indicating when heat is required, comprising:
- a) A gas valve having an inlet and an outlet, where the inlet is adapted to accept gas from a gas supply and the outlet is adapted to supply gas to a gas burner;
b) a spark generator, adapted to mount with the burner such that a spark from the spark generator ignites gas in the gas burner;
c) a burner temperature sensor, adapted to mount with the gas burner and generate a burner temperature signal representative of heat generated by the gas burner;
d) a valve control subsystem, enabling gas flow through the gas valve when the separator indicates that heat is required;
e) a spark control subsystem, enabling the spark generator when both (1) the separator indicates that heat is desired, and (2) the burner temperature signal indicates that the burner has not generated a determined amount of heat.

Abstract
The present invention provides methods and apparatuses for controlling a heater for an oil and gas separator. According to the present invention, a spark is provided for igniting a gas burner. The spark is controlled such that the gas burner is ignited, without unduly complex control or sensor requirements. In the description below, generally an entire temperature-controller separator is described to provide context for the discussion. The invention also contemplates just the heating subsystem, e.g. to mount with existing separators. The invention also contemplates just the heating control subsystem, e.g., to retrofit existing pilot ignition subsystems.
