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

### Furnaces and Boilers | Department of Energy

Energy efficiency upgrades and a new high-efficiency heating system can often cut your fuel bills and your furnace's pollution output in half. Upgrading your furnace or boiler from 56% to 90% efficiency in an average cold-climate house will save 1.5 tons of carbon dioxide emissions each year if you heat with gas, or 2.5 tons if you heat with oil.

### Natural Gas Fired Boilers

⇔ Airflow and flue gas flow is slightly lower or about the same. Natural gas boilers operate at lower excess air (O2) and a different airflow requirement for stoichiometric combustion. Coal fired boilers normally operate with 3-3.5% O2 (about 20% excess air). Whereas natural gas boilers normally operate at 1-1.5% O2 (about 7% excess air).

### Application Note: Flue Gas Analysis as a Boiler Diagnostic

Flue Gas Analysis as a Boiler Diagnostic Tool Overview, and Traditional Application Combustion flue gas analysis has been used by Power Plant Operators for decades as a method of optimizing fuel/air ratio. By measuring the amount of excess oxygen and/or CO in the flue gases resulting from combustion, plant operators can operate at the best

### Analysis of Flue Gas Emission Data from Fluidized Bed

In addition, an important observation is that the content of flue gas could be reduced by as much as 10% (27 mg/) by optimizing the process. Higher bed temperatures seem to favor the reduction of CO in the flue gas (see Figures 3(b) and 6(b)). In this respect, the CO emissions behave conversely to the emissions.
