Gut P. Improvement in performance safety of powerfal hot water boilers.

Small-scale modeling was made of systems to intensify the burning process, experimental and analytical relations of the performance factors to the efficiency of the hot water boiler performance during air pre-heating were obtained. A set of methodology papers were developed, in particular: mixing ejector air pre-heating, evaluation of energy consumption during standby time, evaluation of air inleak into furnace and evaluation of their efficiency Recommended and implemented are measures to minimize corrosion of of heating surfaces and flue ducts, relationships are obtained for protection of the metal of the heating surfaces during standby time. Basic results of the theses have been implemented ito in-service hot water boilers.
