  • Conversion of Existing Coal-Fired Boilers to Natural Gas Firing

    Firing natural gas avoids the slagging and fouling conditions associated with coal combustion, which improves boiler cleanliness and tends to increase heat absorption. However, combustion-zone radiation rates to the furnace walls tend to be lower. Achieving design steam temperatures and full boiler output can be difficult for a boiler originally designed to burn coal. Higher tube-metal temperatures may be experienced when firing natural gas. In some cases, a unit derate of 15% or more, may be necessary to reduce flue gas and tube-metal (superheater, reheater) temperatures in the furnace and convection pass unless upgrades are made to tube material or attemperator nozzles are modified. In other cases, steam temperature derates are seen, since a reduction in excess air is needed for natural gas combustion, which reduces the flue gas flow rate and rate of heat transfer. There are several boiler parameters responsible for the unit and steam temperature derates, which include boiler/burner technology and furnace heat input/plan area ratio. Boiler natural gas …

  • Natural Circulation - an overview | ScienceDirect Topics

    Typically, new scanners or a scanner upgrade will be required when converting from coal to gas. Natural gas flames emit a higher intensity of radiation in the ultraviolet (UV) zone than coal flames and are therefore typically monitored with UV scanners, while coal flames are typically monitored with infrared (IR) scanners. The different flame spectrum wavelength between the two fuels is also attributable to differences in flame emissivity and boiler radiant heat pickup, which is discussed in the boiler …
