Abstract

A well test burner system includes a plurality of burner nozzles. At least one of the burner nozzles includes a well product inlet, an air inlet, an air/well product mixture outlet, and an automatic valve. The automatic valve is configured to automatically adjust a ratio of air and well product supplied to the air/well product mixture outlet based on the well product received via the well product inlet.

First claim

What is claimed is:

1. A well test burner system, comprising:
a plurality of burner nozzles, at least one of the burner nozzles comprising:
a well product inlet;
an air inlet;
an air/well product mixture outlet; and
an automatic valve configured to automatically adjust a ratio of air and well product supplied to the air/well product mixture outlet based on the well product received via the well product inlet, the automatic valve comprising:
a first sleeve with a sleeve air inlet; and
a second sleeve moveable relative to the first sleeve selectively covering the air inlet in the first sleeve, the second sleeve springingly biased towards a minimum flow area of the sleeve air inlet, and

where the at least one burner nozzle further comprises a spring of a predetermined spring rate biasing the second sleeve toward the minimum flow area, and where another of the plurality of burner nozzles comprises a spring of a different spring rate biasing a sleeve of an automatic valve of the other burner nozzle toward a minimum flow area of a sleeve air inlet of the other burner nozzle.

2. The well test burner system of claim 1 , where the sleeve air inlet is automatically changeable in flow area in response to a flow rate of the well product received from the well product inlet.

3. The well test burner system of claim 1 , where the sleeve air inlet is automatically changeable in flow area in response to a viscosity of well product received from the well product inlet.

4. The well test burner system of claim 1 , where the second sleeve comprises a plurality of apertures into an interior of the second sleeve and the second sleeve is moveable relative to the first sleeve to align different numbers of the apertures with the sleeve air inlet of the first sleeve.

5. The well test burner system of claim 1 , where the second sleeve comprises a sleeve well product inlet and the at least one burner nozzle is configured to move the second sleeve with force from a differential pressure upstream and downstream of the well product inlet.

6. The well test burner system of claim 5 , where the greater the differential pressure upstream to downstream of the sleeve well product inlet, the less the second sleeve covers the air inlet into the first sleeve.

7. The well test burner system of claim 5 , where the second sleeve comprises the air/well product mixture outlet out of the at least one burner nozzle.

8. The well test burner system of claim 5 , where the sleeve well product inlet of the second sleeve is configured to promote turbulence in a nozzle tube of the at least one burner nozzle.

9. The well test burner system of claim 1 , where the automatic valve of the other burner nozzle is configured to automatically adjust the ratio of air and well product supplied to an air/well product mixture outlet of the other burner nozzle at a different rate than the automatic valve of the at least one burner nozzle.

10. The well test burner system of claim 1 , where a largest diameter of the air/well product mixture outlet is smaller than a largest diameter of the well product inlet.

11. The well test burner system of claim 1 , where a largest diameter of the air/well product mixture outlet is smaller than a largest diameter of the air inlet.

12. The well test burner system of claim 1 , where the second sleeve is axially moveable relative to the first sleeve to selectively cover the air inlet in the first sleeve.

13. The well test burner system of claim 1 , where the automatic valve is configured to automatically adjust a ratio of air and well product supplied to the air/well product mixture outlet without a controller.

14. The well test burner system of claim 1 , where the automatic valve is configured to automatically adjust a ratio of air and well product supplied to the air/well product mixture outlet without electricity.

15. The well test burner system of claim 1 , where the second sleeve is moved by well product acting on the second sleeve.

16. The well test burner system of claim 1 , where the second sleeve is received within the first sleeve.
