Paper of the Year A Case Study on Coal to Natural Gas Fuel

Since natural gas has only trace amounts of ash, slagging and fouling would not occur. This lack of slagging and fouling may have a hidden risk of leading to more heat transfer problems in the boiler; coal-fired boilers are designed with a default assumption of a

Wet vs dry bottom ash handling compared: one plant's

Another benefit from the adoption of a MAC dry bottom ash system is an increase in boiler efficiency due to the recovery of much of the heat leaving the boiler through the lower opening. This heat is the sum of radiant flux from the furnace, sensible heat and the chemical energy contained in the bottom ash due to its unburned carbon content.
