water boilers zip water heaters and instant hot taps
"Fast boiler furnace designed larger, flue gas recirculation provides a reliable guarantee of space. In the burner head design of the special role of combustion, high temperature flame at the outlet of the flue gas interference, be it in the furnace again achieve full combustion cycle (inner loop). this design helps fast boiler leading domestic level in boiler technology, ultra-low nitrogen oxide, the recent large-tonnage party fast brand integrated condensing boiler successful signing in Beijing, and successfully help China build the APEC summit venue. "Fang boiler fast technical director, said.
Water temperature increase thermal efficiency of the boiler can be divided into two cases to discuss.
The first case, assuming constant evaporation boiler.
Extreme low water level shut off the gas: The top WNSCQ boiler equipped with a gas cutoff limit water level, the use of different conductivity of principle, the water level was lowered to the limit, and when the device failed to pump up water, will immediately stop working burner, gas supply cut off, while the alarm.
Fast side gas produced advanced condensing boiler technology is added, the high temperature flue gas condenses, releasing heat again, while the exhaust gas temperature is also reduced, the following may be less than 120 ℃. From the energy point of saving money, it advocates the use of condensing gas boiler, energy-saving than ordinary gas boiler about 30%.
