YU72395A - Water boiler with additional convective device for the use of heat energy of the exhaust gases - Google Patents

Abstract

Predmet pronalaska je "Toplovodni kotao sa dodatnim konvektivnim uredjajem za iskorišćavanje toplotne energije dimnih gasova", prema osnovnoj prijavi patenta P-418/95, predvidjen za alternativno zagrevanje gasovitog goriva i čvrstog goriva, uključujući i baliranu slamu ili biomasu. Sastoji se iz osnovnog kotla (1) i tri konvektivna uredjaja (2, 3, 4) u kojima su smeštene po četiri dimne cevi (16), medjusobno povezane zaptivnim spojevima, kroz koje odlaze dimni gasovi u dimni kanal (5) i dalje u atmosferu, a izmedju kojih cirkuliše voda, dok je u konvektivnom uredjaju (2) izvedena centralna cev (16') većeg prečnika od prečnika cevi (16). Centralna cev (16') je sa gornje strane zatvorena, a sa donje strane otvorena i povezana sa ložištem (L). Produkti sagorevanja zagrevaju vodu u osnovnom kotlu (1) i dolaze u konvektivni uredjaj (2, 3, 4) gde se hlade zagrevajući vodu za sanitarne svrhe, čime se postiže ušteda goriva, veći stepen korisnog dejstva i smanjenje zagadjivanja okoline.The subject of the invention is "Hot water boiler with additional convective device for utilization of thermal energy of flue gases", according to the basic patent application P-418/95, intended for alternative heating of gaseous fuels and solid fuels, including baled straw or biomass. It consists of a basic boiler (1) and three convective devices (2, 3, 4), each housing four flue pipes (16), interconnected by sealing joints, through which flue gas flows into the flue duct (5) and further the atmosphere, between which water circulates, while in a convective device (2) a central tube (16 ') larger than the diameter of the tube (16) is constructed. The central tube (16 ') is closed on the upper side and open on the lower side and connected to the firebox (L). Combustion products heat the water in the primary boiler (1) and come into a convective unit (2, 3, 4) where they are cooled by heating the water for sanitary purposes, thereby achieving fuel savings, greater efficiency and reducing environmental pollution.
