为满足燃气轮机试验台配置模拟海洋大气环境装置的需求,设计了试验台盐雾系统。该系统通过蠕动泵输送燃气轮机各工况所需要的盐溶液,盐溶液输送至雾化器内雾化后形成盐雾,盐雾在燃气轮机进气道中与燃气轮机吸入的空气混合后进入压气机。在20%,35%,50%,60%,80%和100%等额定功率工况下对压气机进口空气含盐质量分数进行测量计算,压气机进气含盐质量分数均约为0.01×10-6,验证了系统满足燃气轮机全功率工况空气含盐质量分数的模拟要求。

In order to meet the requirements of a set of equipment for simulating marine atmospheric environment on gas turbine testbed,a salt spray system of the testbed was designed,which transported the salt solution required by gas turbine under various working conditions is conveyed by peristaltic pump,and delivered the salt solution to atomizer for atomization.The salt spray mixed with the air inhaled by gas turbine in the gas turbine inlet and then enters the compressor.By measuring and calculating the salt content of compressor inlet air at 20%,35%,50%,60%,80% and 100% power conditions,it is concluded that the saltcontaining mass fraction of compressor inlet air is about 0.01mg/kg,which verifies that the system meets the simulation requirements of saltcontaining mass fraction at full power condition of gas turbine.
