Problems solved by technology
[0002] At present, the utilization rate of fuel mixing in the steam turbine fuel injection device is relatively small, because fuel mixing is time-consuming and laborious, but the combustion ratio of the mixed fuel may be more than twice that of ordinary fuel, so that the steam turbine will be used in production. The resource utilization efficiency is low, which leads to the low power conversion efficiency of the steam turbine. Therefore, it is necessary to design a fuel mixing injection device for the steam turbine to solve the above problems

The invention discloses a fuel mixing injection device of a steam turbine. The fuel mixing injection device comprises a main machine body, a mixing cavity is formed in the main machine body, a stirring and mixing mechanism capable of fully mixing, stirring and pressurizing two dyes is arranged in the mixing cavity, and the stirring and mixing mechanism comprises stirrers fixedly arranged on the upper wall and the lower wall of the mixing cavity. A rotary stirring cavity is formed in each stirrer, a fifth rotating shaft is rotatably arranged on the top wall of each rotary stirring cavity, threestirring blades are arranged on the periphery of each fifth rotating shaft, and the stirring blades can rotate to stir and mix fuel. The two different kinds of fuel are fully mixed through the stirring and mixing mechanism; thus maximization of a combustion ratio of the fuel is achieved, and the resource utilization rate is increased; and through an injection ignition mechanism, the mixing rate of the fuel can be automatically detected, so that the mixed fuel is automatically injected, and the problem that the combustion efficiency of the fuel is low is avoided.
Description
technical field [0001] The invention relates to the field related to steam turbines, in particular to a fuel mixing injection device for a steam turbine. Background technique [0002] At present, the utilization rate of fuel mixing in the steam turbine fuel injection device is relatively small, because fuel mixing is time-consuming and laborious, but the combustion ratio of the mixed fuel may be more than twice that of ordinary fuel, so that the steam turbine will be used in production. The resource utilization efficiency is low, which leads to the low power conversion efficiency of the steam turbine. Therefore, it is necessary to design a fuel mixing injection device for the steam turbine to solve the above problems. Contents of the invention [0003] The object of the present invention is to provide a fuel mixing injection device for a steam turbine, which is used to overcome the above-mentioned defects in the prior art. [0004] A fuel mixing and injection device for a...
