Thermal & Metallurgical
coal
Despite the growth of renewable and sustainable sources of energy, coal is still a resource we depend on to fulfill both demands for energy and steel production
ELDER PROJECT LP
offers high quality Australian coal to solve industrial & energy problems. Thermal coal or steaming coal is burned for steam to run turbines to generate electricity either to public electricity grids or directly by industry consuming electrical power (such as chemical industries, paper manufacturers, cement industry and brickworks). In the process of power generation the coal is ground to a powder and fired into a boiler to produce steam to drive turbines to produce electricity.

Metallurgical coal or coking coal is used in the process of creating coke necessary for iron and steel-making. Coke is a porous, hard black rock of concentrated carbon that is created by heating bituminous coal without air to extremely high temperatures. Coals offered by our company can be found in Illawarra, Hunter Valley and Bowen Basin. Using the feedback form, you can send us your request and our specialists will offer the best coal types and fraction sizes.

Metallurgical coal

We have the possibility of supplying three types of Australian metallurgical coal: Hard Coking Coal, Semi-Hard Coking Coal and Semi-Soft Coking Coal

Hard Coking Coal

(HCC)

high rank producing strong coke and commanding premium prices

Semi-Hard Coking Coal (SHCC)

medium to high rank producing reasonable strength coke and discounted from HCC price

Semi-Soft Coking

Coal (SSCC)

low rank producing weak coke and significantly discounted from HCC price

PROPERTIES OF AUSTRALIAN COKING COALS AND COMPARISON TO INTERNATIONAL ALTERNATIVES

Thermal coal

The Australian thermal coal we offer is as good as any other coal mined in the world, and in some cases even takes the lead. See for yourself!
The Australian coal offered by ELDER PROJECT LP has the following advantages over other coals mined in the world
Advantages of Australian thermal coal to the power utility customer
  • Total Moisture
The lower moister level the better. Higher moisture coals have lower boiler efficiencies. Australian coals are mid-range at 10.6 %.
  • Proximate Analysis
This includes the percentage of moisture (air dried), ash, volatile matter (VM) and fixed carbon (FC). Lower ash levels are therefore preferred. The Fuel Ratio (FR) which is the ratio FC/VM is sometimes specified to judge PF burnout. The FRs for Australian coals are satisfactory.
  • Ultimate Analysis
This includes the percentage of the main organic constituents of the coal and is made up of carbon, hydrogen, nitrogen, sulphur and oxygen. Of most importance here is the level of sulphur. The sulphur in the coal forms sulphur oxides SO2 and SO3, on combustion. Lower levels are desirable. Australian coals all exhibit lower levels of sulphur (<0.6 %).
  • Specific Energy (SE)
This is the amount of heat liberated per unit mass of coal when it is burnt. Clearly, the higher the SE the better for lower cost electricity production. Australian coals have the higher SE at 25 megajoules per kilogram (MJ/kg).

  • Ash Analysis
This is the chemical composition of the ash in the coal, reported as oxides. Various chemical constituents in the ash can impact ash fusion temperature, ash slagging and fouling in the boiler and fly ash properties.
  • Ash Fusion Temperature (AFT)
This is the temperature at which the ash in the coal melts. It is normally measured in a reducing atmosphere and correlates with various melting properties of the ash in the boiler. Again, specification levels are boiler specific, but in general, initial deformation temperatures in excess of 1200⁰C are desirable.
  • Hardgrove Grindability Index (HGI)
This is an empirical test which measures how easily a coal can be ground. This can impact the fineness of PF grind, the number of mills required and the parasitic load within the power station to run them. Generally, HGI of greater than about 45 to 50 is desirable. Australian coal is satisfactory with HGIs in excess of 50.
  • Trace Elements
These are chemical elements which occur in the coal at low concentrations which can be released into the environment on utilization of the coal. Lower levels are desirable. Australian coals have significantly lower levels of arsenic, boron, mercury and selenium than international coals.
  • CO2 Emissions
Carbon dioxide emissions on combustion of coal vary with both the technology used and the coal properties. For commentary on the role of modern, high efficiency low emission (HELE) plants in achieving lower CO2 emissions see below.
