BURNER CLEANING DEVICE Russian patent published in 2011 - IPC F23D11/38 

FIELD: power industry.

SUBSTANCE: burner cleaning device (1), namely gas turbine burners at least with one fuel nozzle (13) and at least one fuel supply line (15) leading to fuel nozzle, includes at least one flushing head (3) with hole (33), at least one line (5) for flushing liquid and pump (37); at that, pump (37); flushing head (3) and line (5) for flushing liquid are hydrodynamically connected to each other, thus forming flow path subsequently streamlined with flushing liquid; device differs by the fact that flushing head (3) is made so that it can be put with its hole (33) on fuel nozzle (13) of burner (1) to provide the supply of flushing liquid to nozzle (13) and its removal from it, and line (5) for flushing liquid is provided with possibility of being connected to fuel supply line (15) of burner (1) to provide the supply of flushing liquid to fuel supply line (15) and its removal from it; at that, flushing head (3) is provided with possibility of being inserted through outlet hole (31) of burner to fuel nozzle (13) directed into its air supply channel (9). Flushing head (3) is equipped at least with one seal (35) enclosing its hole (33), provided and located on flushing head (3); at that, when flushing head (3) is put on nozzle hole (13), seal (35) envelopes nozzle hole (13). Flushing head (3) includes wall (21) in the form of cylinder or flattened cone, and hold-down device is made in the form of the pressure creating device located on outer side of wall (21). Pressure creating device is made either in the form of compression spring (36), or in the form of inflatable hose. Device includes filter (39) connected to flow path, tank (41) and valve (43). Flow path leads back to valve (43) which has at least two positions opening the flow path; at that, in one of its positions, which opens it, direction of flushing liquid flow through flushing head (3) and/or line (5) for it is reverse in relation to direction of flow in the other position opening the flow path.

EFFECT: invention provides cleaning of burner without its removal.
