Burner cleaning device
A burner cleaning device for cleaning burners, in particular for gas turbine burners, with a fuel nozzle and a fuel supply line is disclosed. The burner cleaning device has a rinsing head provided with an opening that is placed on a fuel nozzle of the burner and that enables a rinsing fluid to be supplied to or evacuated from the nozzle, and/or a fluid line that is connected to the fuel supply line of the burner and that enables the rinsing fluid to be supplied to or evacuated from the fuel supply line, and a pump. The pump, the rinsing head and/or the fluid line are fluidically interconnected such that they form a flow path through which the rinsing fluid sequentially flows.
1. A burner cleaning device for cleaning burners, each burner including a fuel nozzle and a fuel supply line leading to the fuel nozzle, comprising:
a rinsing head with a rinsing head opening;
a fluid line; and
a pump,
wherein the pump, the rinsing head and the fluid line are fluidically interconnected such as to form a flow path along which a rinsing fluid sequentially flows,
wherein the rinsing head is placeable by the rinsing head opening onto the fuel nozzle of a burner and enables the rinsing fluid to be fed to or evacuated from the fuel nozzle,
wherein the fluid line of the cleaning device is connectable to the fuel supply line of the burner and enables the rinsing fluid to be fed to or evacuated from the fuel supply line such that an entire fuel supply system of the burner is cleaned, and
wherein the rinsing head is insertable through a discharge opening of the burner up to a fuel nozzle opening out in an air supply channel of the burner,
wherein the rinsing head includes a tensioning device by which the rinsing head is tensionable against a wall of the air supply channel disposed opposite the fuel nozzle opening, and
wherein the rinsing head is provided with a seal that surrounds the rinsing head opening and is embodied and arranged on the rinsing head such as to surround the fuel nozzle opening when the rinsing head has been placed onto the fuel nozzle.
2. The burner cleaning device as claimed in claim 1 , wherein the device is for cleaning gas turbine burners.
3. The burner cleaning device as claimed in claim 1 , wherein the rinsing head includes a wall that is cylindrical or shaped like a truncated cone, and wherein the tensioning device is a pressure producing device located on the exterior of the wall.
4. The burner cleaning device as claimed in claim 3 , wherein the pressure producing device is a compression spring.
5. The burner cleaning device as claimed in claim 3 , wherein the pressure producing device is an inflatable hose.
6. The burner cleaning device as claimed in claim 1 , further comprising:
a filter connected into the flow path.
7. The burner cleaning device as claimed in claim 1 , further comprising:
a tank connected into the flow path.
8. The burner cleaning device as claimed in claim 1 , further comprising:
a valve connected into the flow path.
9. The burner cleaning device as claimed in claim 8 , wherein the flow path leads back to the valve and the valve has at least two valve positions releasing the flow path, wherein the rinsing fluid's flow direction through the rinsing head and fluid line is in one releasing valve position opposite the flow direction in the other releasing valve position.
10. The burner cleaning device as claimed in claim 7 , wherein the flow path has a section through which fluid always flows in the same flow direction regardless of the releasing valve position and in which the filter is located.
11. The burner cleaning device as claimed in claim 8 , wherein the flow path has a section through which fluid always flows in the same flow direction regardless of the releasing valve position and in which the filter is located.
12. The burner cleaning device as claimed in claim 1 , wherein the rinsing fluid has demineralized water or a solvent.
