Embodiment Construction

[0020] The embodiments of the present invention are described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways as defined and covered by the claims.

[0021] see figure 1 , a fuel atomizing nozzle, including a nozzle body 1, an air filter 21, an oil filter 31, a spring bracket 4, a spring 5, a swirler 6, a fuel nozzle 7 and a nozzle cover 8.

[0022] The nozzle body 1 has an L-shaped structure. Inside the long arm of the nozzle body 1, a fuel oil inlet pipe 3 and an air inlet pipe 2 are opened. The fuel inlet duct 3 and the air inlet duct 2 are arranged in parallel. Both the fuel oil inlet pipe 3 and the air inlet pipe 2 are round pipes. The inlet end of the fuel oil inlet pipeline 3 is provided with a member for connecting to the fuel supply device (not shown in the drawings). The inlet end of the air intake duct 2 is provided with a member for connecting an air supply device (not shown in the...

Abstract

The invention provides a fuel-oil atomizing nozzle and a gas turbine with the same. The fuel-oil atomizing nozzle comprises a nozzle body (1) and a fuel oil nozzle (7), wherein the nozzle body (1) is provided with a fuel oil inlet pipeline (3) and an air inflow pipeline (2); the fuel oil inlet pipeline (3) and the air inflow pipeline (2) are respectively communicated with the fuel oil nozzle (7); the fuel-oil atomizing nozzle also comprises an oil filter (31), an air filter (21) and a swirler (6), wherein the oil filter (31) is accommodated at the interior of the air filter (21); and the oil filter (31) is respectively communicated with the fuel oil inlet pipeline (3) and the air inflow pipeline (2), the swirler (6) is accommodated at the interior of the fuel oil nozzle (7), and the swirler (6) is communicated with the oil filter (31). The fuel-oil atomizing nozzle provided by the invention is provided with an air inlet pipeline, the high pressure air is introduced to a nozzle, the high pressure air passes through a threaded air filter and is converged with the fuel oil at a nozzle spout; and the atomizing effect of the fuel oil is better, and the distribution is more uniform, thereby improving the combustion efficiency of the fuel oil and improving the starting performance of the gas turbine.

Description

technical field [0001] The present invention relates to the field of gas turbines, in particular, to a fuel atomizing nozzle of a gas turbine. In addition, the present invention also relates to a gas turbine having the above fuel atomizing nozzle. Background technique [0002] The fuel nozzle is an important part of the combustion chamber of the gas turbine. The performance of the fuel nozzle is directly related to the performance and life of the entire combustion chamber. The atomization performance of the fuel nozzle and the uniformity of fuel distribution are important factors that affect the outlet temperature of the combustion chamber. . At present, the fuel nozzles of gas turbines are mostly centrifugal nozzles, and the fuel oil forms a certain atomization cone angle in the combustion chamber, so that it can better participate in the combustion. However, the existing centrifugal nozzle only uses one oil inlet pipeline, and when the temperature is low, the atomization...
