18.10.2015  CONVERSION OF COAL INTO COKE Coke oven gas burns with yellowish flame because of the presence of CH 4. Actual flame tempr of fuel depends upon -calorific value of the fuel -volume -specific heats of the flue gas -extent of endothermic dissociation of CO2 H2O present in the flue gases. Burning of coal in absence of air is called carbonisation of coal. -Low tempr carbonisation -High tempr carbonisation Low tempr carbonisation takes place at 700 0C. Low tempr carbonisation of coal

Coal and Coke - Cargo Handbook - the world's

Most classes of coal, particularly those to be used for coke-making, and of coke will suffer deterioration or depreciation in value by contact with salt water although quality, calorific value apart, is seldom affected by contact with fresh water. Particular care must be exercised in arriving at depreciation or loss arising from spontaneous combustion, heating or water damage. The effects can range from a

coke and metallurgical coal - SlideShare

Metallurgical Coke Manufacturing Metallurgical coke is made from low ash, low sulfur bituminous coal, with special coking properties, which is inserted into ovens and heated to 1000F to fuse fixed carbon and inherent ash and drive off most of the volatile matter. The final product is a nearly pure carbon source with sizes ranging from basketballs (foundry coke) to a fine powder (coke breeze).

How does coke and coal play into steel

22.06.2016  Typically coal preparation involves drying and grinding coal to tiny particles of less than 1mm for injection. The coal particles are separated from released gases in a cyclone. The waste gas, and sometimes natural gas, can be used for drying additional coal, which is generally kept below 6% moisture content. Inert gases are used to minimize the risk of fire or ignition of the coal particles ...
