Fuel oil boiler XC-K 69-1550

for heating onlyindustrialoutdoor

Large water content, pressurized, condensing boiler, with outer shell in high resistance carbon steel, with reversed flame combustion chamber Tube bundle made of special patented smoke pipes in stainless steel AISI 316 L, rolled on other inner stainless steel AISI 304 sectorial pipes (6x60°) complete with turbulators, also in AISI 304. Suitable for pressure jet oil, biodiesel or dual fuel burners, in two stage or two stage progressive modulating type. Rear smoke chamber in stainless steel AISI 304 with connection for condensate drain. Combustion chamber, front and rear tube plate in stainless steel AISI 316 L. The combustion chamber is positioned above the tube bundle and the water around it is so guided to optimize for thermal exchange The tube bundle is slightly slant toward the smoke chamber for: - functional outflow of the condensates - absence of wet acidic deposits - cleaning for gravity of the exchange surfaces Good silent operation due to the low smoke side resistance Front door in carbon steel insulated with special superlight recyclable cement (30% reduction of the heat losses due to radiation) C.H. flow connection and two C.H. return connections, for high and low temperature circuits, are placed on the rear side for the model 100, and on upper side for models 250 to1550) High temperature return connection positioned so that not interfere with the low temperature return connection. The low temperature return connection is placed on the outer shell of the tube bundle for the maximum recovery of the heat. The combustion chamber door is adjustable and with reversible opening.
