1950—1960 — methods of transferring heating boilers and furnaces to gas. Straight-slot bottom burners were utilized on 3000 steam and water-heating boilers, methods of transferring the furnaces to gas were utilized on 500000 furnaces. 1960—1965 — special gas water-heating boilers TVG (and their modification, KVG) with the productive rate of 4..10 MW. 8500 boilers in operation: heat supply for Ukrainian cities, Moscow region, the Volga region, Siberia, the Baltic states. 1965—1980 — methods of thermal cleaning of gaseous emission in boiler combustors, implemented at 20 plants. 1966—1990 — the mechanism and methods of lowering nitrogen oxidation in boilers. Staged combustion burners as well as other developments were implemented on the boilers at major power plants and boiler stations of the cities of Kyiv, Moscow, Lviv, Kazan, Surgut, Vilnius, Riga, Sofia, etc. (with the total of over 1000 boilers). 1991—2007 — methods of modernization of potent water-heating boilers, (Darnitsa TPP, «Zhitomirtempokommunenergo»). 2000—2007 — processes and burner devices for biogas combustion in steam boilers (Bortnicheskie sewage treatment plants, city of Kyiv; alcohol plants, city of Electrogorsk (Russia), Luzhany (Ukraine). == Major Monographs ==
