To convert the units to operate solely on natural gas, existing equipment will be modified, such as the boilers, fans and control systems. In addition, new equipment will be installed including: natural-gas burners, igniters, scanners, piping and valves; while coal-handling equipment will be retired, cleaned and stored in place.

Natural gas fired boiler installed at SAB plant - EE

The main objective was to cease the use of coal fired boilers. SAB substituted their coal fired boilers by installing two new natural gas fired boilers and converting two coal-fired boilers to natural gas with energy savings of between 13 and 32%. Natural gas was chosen because it is one of the least contaminated fuels used for boiler operation.

The boiler efficiency is usually reduced to 84-85%, when a coal fired boiler is converted to natural gas. The biggest change is due to the combustion of Hydrogen. This is normally a 4% heat loss while firing coal and about a 11% heat loss while firing natural gas.

Unit 10 was originally a stoker fired coal and bark boiler rated for 225,000 pph main steam flow. In 2014, all three boilers were converted to fire natural gas only. Riley Power Inc. and TEi Construction Services Inc. were contracted by the facility to supply engineering services, equipment, construction, and commissioning for the gas conversion.

Boiler natural gas feasibility studies are required to determine the effects of burning natural gas in a coal -fired boiler. Coal and ash handling equipment are not required if firing natural gas; in most cases, these will be abandoned in place or will be removed to the extent necessary to carry out the conversion.

    Challenges when Converting Coal-Fired Boilers to Natural Gas

    It is typical when converting to natural gas from coal firing for the FEGT to increase. The reason this occurs is because the emissivity of the flame from natural gas firing is lower than that for coal. Therefore furnace water wall absorption is typically lower with natural gas firing.
