  1. Types of Coal Coal 2500Average Temperature Average = 7 % Ash, 93 % Carbon13,000 BTU Grades of Coal: Metric Anthracite Anthracite Bituminous Sub Bituminous Lignite Ranges Waste Coal 1700Average Temperature Average = 49 % Ash, 51 % Carbon5,000 BTU (4336) Ranges 96-97 Parts of Waste Coal and 3-4 Parts of Limestone Are added to produce the final mixture

  2. CFB Waste Coal Mixture Waste Coal Coal Refuse 90 - 97 % Waste Coal Illite Kaolinite Pyrophylite Pyrite (Sulphur) Rutite Carbon Plus Limestone 3 - 10 % Limestone Limestone Added (All Rock 100% Ash) to control SO2 levels. Carbon is the key component that burns. Ash is the naturally occurring “rocks” elements found in the local area. When a “lump” of coal is burned the ash that remains is the rock elements (%) found in the lump of coal. The carbon burns off to produce energy.

  3. CFB Environmental Controls AIR SO2 NO2 Mercury Opacity CO2 Stack/Chimney Fuel (Wood/Coal) ASH – (Beneficial Use) CFB Waste Coal Ash Monitored Controlled Elements Found in Carbon Burning (Coal) Process:1. Sulphur (SO2) – Limestone Control2. Nitrogen (NO2) – Low Temperature – More Oxygen 3. Mercury 4. Opacity (Particulates PM 10 – 5 – 2.5)5. CO2 6. Water (Cooling + Storm Water Controls) (+ 3% Limestone/Ash) CFB Ash Content The Waste Coal/Limestone Mixture is very alkaline ash with low permeability and benign chemical properties, making it safe and ideal for abandoned mine reclamation.
