Abstract
The utility model relates to a fuel nozzle for a burning machine trail run, which aims to solve the problems that the burning machine needs a trial station burning gas for trail run which is large investment and high cost, the fuel nozzle by fueling way for trial run is arranged. The fuel nozzle is divided into an elevation segment, a vertical segment and a level segment from upper to lower on foundation of retaining the original nozzle structure, the angle between the elevation segment and vertical segment is 35 degrees to 55 degrees. The elevation segment is also equipped with a fixed plate, the elevation segment above the fixed plate is equipped with a level tube joint parallel with the fixed plate, and the level tube joint is communicated with a main pipe line and a II-grade swirler in sequence. A vertical tube joint that is communicated with a vice pipe line, a filtration core and a I-grade swirler is arranged at the top of the elevation segment in sequence. Compared with the prior fuel nozzle, the utility model has the advantages of simple structure, high reliability and being matched loading with the burning machine easily.
Description
Affiliated technical field
