condensing boiler - higher return temp == higher

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.

The influence of flue gas temperature on lead chloride

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.

Material Considerations in Boiler Design

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.

What temperature should a condensing boiler be set at

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
