We are providing coal testing services.
We sigma is equipped with bespoke lab facilities and expertise to provide coal sampling and testing, as well as other support services like ultimate analysis, proximate analysis, calorific value (grossnet) and ash analysis for the coal mining and processing industries. Leverage our technical capabilities to guarantee that your coal analysis meet global standards for quality and excellence.
Coal testing solutions offered assists in offering quality testing of coal on different parameters. Among the many tests performed, one includes proximate analysis - moisture, volatile matter, ash and fixed carbon test that indicates percentage by weight of volatiles, fixed carbon, ash as well as moisture content in coal. Here, the high volatile matter content helps in indicating easy ignition of fuel. Further, the ash content is also important in design of pollution control equipment, ash handling systems of furnace, furnace grate, combustion volume and others. Some of the other checks done for coal testing include:
calorific value (grossnet) �
testing calorific value or heat of combustion or heating value of sample of fuel
ultimate analysis �
test is used for determining different elemental chemical constituents like oxygen, sulphur, carbon, hydrogen
it is used in determining quantity of air needed for combustion, volume as well as composition of combustion gases
ash analysis �
the test is done to conduct ash analysis and is done with coal thoroughly burnt and ash material expressed as percentage of original weight
ash fusion temperature �
these tests are part of development of automated techniques for performing measurement requiring no intervention by operator
here, fusion temperatures are valuable guides to high-temperature behavior of fuel inorganic material
