Abstract

A system includes a pre-assembled, modular valve assembly configured to be coupled to both an industrial gas appliance and a fuel supply system for the industrial gas appliance. The system includes a manual isolation valve, a first block valve, and a bleed valve. The modular valve assembly is configured to be disposed at a location separate from the industrial gas appliance.

First claim

1 . A system, comprising:
a pre-assembled, modular valve assembly configured to be coupled to both an industrial gas appliance and a fuel supply system for the industrial gas appliance, comprising:
a manual isolation valve;
a first block valve; and
a bleed valve;
wherein the modular valve assembly is configured to be disposed at a location separate from the industrial gas appliance.

2 . The system of claim 1 , wherein the modular valve assembly comprises a skid that supports the modular valve assembly.

3 . The system of claim 1 , wherein the modular valve assembly is configured to operate with different industrial gas appliances.

4 . The system of claim 3 , wherein the modular valve assembly is configured operate within a range of different operating pressures to enable operation with the different industrial gas appliances.

5 . The system of claim 1 , wherein modular valve assembly comprises a second block valve.

6 . The system of claim 1 , wherein the modular valve assembly comprises a manual bleed valve.

7 . The system of claim 1 , wherein the modular valve assembly is configured to be utilized in shutdowns operations of the industrial gas appliance.

8 . The system of claim 1 , wherein the modular valve assembly is configured to be utilized in valve leakage tests for the industrial gas appliance.

9 . The system of claim 1 , wherein the modular valve assembly comprises a first pressure transducer configured to monitor a gas pressure for startup of the industrial gas appliance.

10 . The system of claim 9 , wherein the modular valve assembly comprises a second pressure transducer configured to be utilized in a gas leakage test external to the industrial gas appliance.

11 . The system of claim 1 , comprising the gas turbine appliance, wherein the modular valve assembly is disposed approximately 1.5 to 6 meters from the industrial gas turbine appliance.

12 . The system of claim 1 , wherein the industrial gas turbine appliance comprises a gas turbine engine, a combustion engine, a generator, a gas turbine engine-generator package, or a combustion engine-gas generator package.

13 . A system, comprising:
a universal skid assembly configured to be utilized with different industrial gas appliances, wherein the universal skid assembly comprises a modular valve assembly comprising:
a manual isolation valve;
a first block valve; and
a bleed valve.

14 . The system of claim 13 , wherein the universal skid assembly comprises a skid that supports that supports the modular valve assembly.

15 . The system of claim 13 , wherein the universal skid assembly comprises a pressure transducer configured to be utilized in a gas leakage test external to the industrial gas appliance.

16 . The system of claim 13 , wherein the universal skid assembly is configured operate within a range of different operating pressures to enable operation with the different industrial gas appliances.

17 . A system, comprising:
a pre-assembled, modular valve assembly configured to be coupled to both an industrial gas appliance and a fuel supply system for the industrial gas appliance, comprising:
a manual isolation valve;
a first block valve; and
a bleed valve;
wherein the modular valve assembly is configured operate within a range of different operating pressures to enable operation with different industrial gas appliances.

18 . The system of claim 17 , wherein the range of different operating pressures comprises 6.9 to 3,447 kPa.

19 . The system of claim 17 , wherein the range of different operating pressures comprises 3447 to 6,894 kPA.

20 . The system of claim 17 , wherein the range of different operating pressures comprises 6894 to 10,342 kPa.
