    Coil boiler. These are a 'once through' type of water tube boiler, and referred to in some regulations as, 'boilers with no discernible water level'. Water supply to the boiler will usually be at 10 to 15% above the steaming rate to: Ensure that all the water is not evaporated, thus ensuring that superheated steam …Learn More

  • 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).Learn More

  • Gas boilers - flues in voids

    Dec 02, 2010 · Where boilers are located away from external walls, flues are more likely to run through ceiling (or wall) voids. In such cases when the gas appliance is serviced or maintained it can be difficult, or impossible, to determine whether the flue has been installed correctly or whether it …Learn More

  • Flue Gas - an overview | ScienceDirect Topics

    For these cases, flue gas, called synthetic gas (syngas) in some cases, is generally reducing, and contains gaseous H 2 S, resulting from sulfur in fuel. For some industrial boilers, slightly air-deficient combustion is favored at their furnaces, in order to minimize formation of gaseous nitrogen oxides. Gaseous H 2 S exists in the flue gases Learn More

  • Air Pollution Aspects Of Emission Sources Boilers

    However, the high flue-gas speeds and the higher circumferential speed of the ventilator make them noisier than conventional boilers. In addition, the small flue-gas ducts which are necessary to obtain a high flue-gas speed make flue-gas cleaning more difficult. Finally, boiler and burner are not always tuned to each other satisfactorily.Learn More
