COAL, COKE & IRON ORE TESTING FURNACES | INTRODUCTION Carbolite Gero’s expertise in coal, coke and iron ore testing The characterisation of coal is important for its quality assessment. The most common types of coal (lignite, bituminous and anthracite) can be distinguished by their different chemical and physical properties. Depending on the product quality, coal is suitable for a variety of uses including coking, steel production and power generation. The formation of coal from a variety of plant materials via biochemical and geochemical processes is called coalification. The nature of the...

FURNACES & OVENS FOR PROXIMATE ANALYSIS up to 210  C ° 0 MFS/1 – Minimum Free Space Oven From its natural development to its processing, coal contains an amount of moisture which needs to be quantified. One method of quantifying moisture in coal is by measuring the weight loss of a sample after drying. The MFS is used for this drying process and has a small heated chamber to provide the lowest practical volume, ie, minimum free space, as required by the test standards. A known mass of the coal is heated in a stream of nitrogen or air at a temperature between 105  and 110  and maintained at...

FURNACES & OVENS FOR PROXIMATE ANALYSIS up to 200  C ° 0 CD range – Coal Drying Ovens (CDLT & CDHT) The measurement of total moisture is required to determine whether coal meets commercial or environmental specifications, or both. Since coal can vary from extremely wet to completely dry, special emphasis must be placed on the sampling, sample preparation and the moisture determination itself to ensure total reliability of measurement. The Carbolite Gero coal drying range of ovens consists of the CDHT (Coal Drying High Temperature) with a normal operating temperature of 105  and CDLT (Coal...

FURNACES & OVENS FOR PROXIMATE ANALYSIS up to 1000  C ° 0 VMF – Volatile Matter Furnaces Volatile matter in coal, ie, the matter given off before oxidisation, refers to the volatile components of coal, except moisture, which are removed at high temperature in the absence of air. This is usually a mixture of short and long chain hydrocarbons, aromatic hydrocarbons and some sulphur. Volatile matter is determined as the loss in mass, less that due to moisture, when coal or coke is heated out of contact with air under standardised conditions. The test is empirical and, in order to ensure...

FURNACES & OVENS FOR PROXIMATE ANALYSIS up to 1100  C ° 0 AAF – Coal Ashing Furnaces The ashing process determines the amount of ashforming material present in a petroleum product to enable a decision on its use in certain applications. Ash-forming materials are considered to be undesirable impurities or contaminants. The ash remaining after coal or coke has been incinerated in air is derived from inorganic complexes present in the original coal substance and from associated mineral matter. The amount of sulphur retained in the ash is in part dependent on the conditions of ashing and, in...
