Abstract
Based on the analysis of scientific, technical and patent information, defects and destructions of the main structural elements of injecting steam coolers (ISC) identified during the operation of boilers, in particular their nozzles, the main processes affecting the ISC resource are noted. Using the results of the analysis and the current state of research on improving the reliability and resource of the ISC, the ways of improving the main elements of the ISC design are formulated, which are aimed at improving the reliability and resource of the ISC while maintaining the high quality of spraying with cooling water nozzles. These ways include the selection of promising materials of nozzles and optimization of the design of nozzles and other parts of the ISC with the identified potential fracture zones, modeling of the stress-strain state, temperature fields of nozzles and ISC as a whole, features of the distribution of media flows and velocity distribution fields of media in nozzles and ISC as a whole, erosive wear of their surfaces, the process of cracking, etc. the development of cracks.
