Boiler Operations That Affect Efficiency (Part 2)

⇔ 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).

Flue Gas - an overview | ScienceDirect Topics

Typical flue gases from natural gas-fired power plants may contain 8-10% CO 2, 18-20% H 2 O, 2-3% O 2, and 67-72% N 2; typical flue gases from coal-fired boilers may contain 12-14 vol% CO 2, 8-10 vol% H 2 O, 3-5 vol % O 2 and 72-77% N 2.

Measurement and calculation of calorific value of raw coal

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 percent excess air for this combustion system is 10 %. The combustion air is drawn from the home at 70 F and 35 % Relative Humidity.
