Example #1 - Determination of the Flue Gas Temperature from a Natural Gas Furnace In this specific example the combustion device is an older lower efficiency Natural Gas Home Furnace. The fuel is considered to be Standard Natural Gas (1040 Btu/std. ft3 ), the fuel consumption is 100,000 Btu/hr (HHV Basis), and the heat delivered to the home is 80,000 Btu/hour.
Is our oil boiler heating water to the correct temperature
increase in OD crown temperature over the scale free condition for several Q/ Ao values. Figure 3-6 are plot- ted for specific superheater or reheater conditions. It is instructive to calculate the various contributions to the overall flue gas temperature to steam temperature drop each component makes. With Scale (0.019 inch) 270F 6700 Btu/hr/ft2
Power 101: Flue Gas Heat Recovery in Power Plants, Part I
07/10/2016 · A condensing boiler; also known as a condensing hot water heater although referred to as a boiler in this article, is a type of boiler that is much more efficient than the traditional type appliance. Extra efficiency is achieved by extracting more energy out of the flue gas as compared to that of a conventional boiler and using this energy to pre-heat the return water flowing into the boiler.
The reverse heat transfer of the sinter cooler produced by the Company makes the temperature of the hot exhaust gas stable and comprehensively improves the quality of the recovered sintered heat, while keeping the hot exhaust gas temperature of all the coolers at 450 ~ 550 ℃, which is about 150 ° C higher than the temperature of the conventional cooler outlet hot exhaust gas.
condensing boiler - higher return temp == higher

01/04/2010 · The sensible heat that could be recovered from the flue gas by cooling it in a flue gas cooler (FGC) from the APH gas outlet temperature of 310F to the FGD inlet temperature
For the boiler to work at its most efficient, the heat exchanger needs to be equal to or below the dew point temperature. The dew point temperature is a measurement that determines the humidity of air and is the temperature at which water droplets form in the heat exchanger. For gas boilers
