THE HEAT EXCHANGER SYSTEM BY A CONDENSING TYPE BOILER

摘要

PURPOSE: A condensing type heat exchanger system of a boiler is provided to miniaturize a heat exchanger by enlarging a heating surface by forming a bellows pipe made of the stainless steel with storing corrosion resistance. CONSTITUTION: A condensing type heat exchanger system of a boiler comprises a casing(10), a burner(22), a supply tube(40), upper and lower caps(20,30) and a S-bent portion(S). The casing is installed in the burner and the interval holding protrusion. The burner receives gas and air through the supply tube and produces combustion heat.
