<p class="0abstract">This paper describes the comparative analysis of nozzles efficiency in high pressure water vapor systems based on different operating time and quality of their work. These nozzles described the size of water droplet and convert it into moisture. Which help to manage the room temperature. Literature survey revealed an insufficient number of studies in the field of stability and reliability of nozzles.As, it is the strong candidate in performance of the humidifiers.The purpose of this work is to test and complement the results of the received theoretical provisions, the establishment of values of the rational time of operation of the nozzles. The action plan includes laboratory and industrial tests. The main parameters focused here, were the contamination of the nozzle filters at their different operating times, the performance of the nozzles with variable operating time, as well as the nozzle spray torch, and most importantly the quality of the injector.The cone shaped nozzle was used to test the effectiveness of the spray by assuming that the water torch is coming from the nozzle. Weight method was used to estimate the degree of contamination in filters. In this study, it was found that nozzle filters increase their weight by more than 45% when operating for more than 1,500 hours, which reduces their throughput and, as a result, reduces the performance of the injectors by more than 20%. In this case, the spray torch does not cover the required area, which leads to deterioration of the system and the appearance of micro-drafts. Experimental studies have shown the need for maintenance of injectors within 1200-1300 hours of operation. Moreover, the increase in contamination of the filter effects the performance of the filter. And the stability of the diameter of the torque torch explained by critical clamping of the nozzle filter.<strong></strong></p>
