Money saving ...Operating efficiency levelsupto and over 108% !The condensing technology has the primaryscope of drastically reducing latent heat(contained in water vapour), which is lostthrough the flue system, thereby exploitingto the utmost the energy containedin the gas burned and giving the condensingboiler an exceptionally high levelof operating efficiency, impossible to reachwith conventional boilers.The ALKON’s 50 heat exchanger/condenserhas been designed so that the system’sreturning cold water passes throughits terminal part: the contact of the fluegases with this cold surface causestheir transition from the vapour phaseto the liquid phase (condensate),with the subsequent release of heat tothe C.H. system water.This process therefore enables the boilerto recover nearly 1 kW per m 3 of gas burned,which normally, with traditional combustion,would be lost to the environmentwith the flue gasses.Combustion/condensation phenomenonALKON<strong>Condensing</strong> boilerCONVENTIONALBOILERUSEABLECONDENSING HEAT+12%- 2 % - 1 %100% 112% 110% 109%UNUSEABLECONDENSING HEATFlue sidelossesFlue sidelossesRadiatonlossRadiatonloss- 7 % - 1 %100% 100% 93% 92%FUEL SAVINGThe energy efficiency indicated is the “Net calorific value”Thus the ALKON 50's and ALKON 70'suseful efficiency reaches 109%!Seasonal efficiency, which is stronglyinfluenced by the heating load factor,which is to say, by the variations of usageaccording to the climatic conditionsand the type of heating system, alwaysmaintains itself at very high levels, placingthis boiler at the top of today’s technology.
... with condensationMathematicalintelligenceAs evidenced in the diagram, with the samehours of boiler operation, if you comparea conventional boiler with an ALKON boiler,you can see that the efficiency of this lastboiler is proportionally the opposite to theheat input requested by the heating system,always maintaining itself greater then avery efficient conventional boiler.Infact, the ALKON can supply a 10% higherefficiency rate compared to a conventionalboiler. Moreover, during the milder season,at the minimum load, the differential infavour of the ALKON reaches upto 19 %.CONVENTIONAL BOILERALKONEfficiency (%)10910210092,590802 3 4 7812 1211 11 1110 10 109 8 87685 45332OTT.
