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).? Steam and exit gas temperatures. Upon switching from coal to natural gas, heat transfer characteristics of a boiler will be impacted.
4. Leave a permanent access space of 30 inches opposite the float level control, the sparge tube/temperature control valve (where applicable) and the pump(s) location.
