The PCI method is based on the simple concept of primary air (termed the "conveying gas") carrying pulverized coal which injected through a lance to the tuyere (mid-bottom inlet of a blast furnace), then mixed with secondary hot air (termed the "blast") supplied through a blowpipe in the tuyere and then piped to a furnace to create a balloon ...
Metallurgical coal or coking coal [1] is a grade of coal that can be used to produce good-quality coke. Coke is an essential fuel and reactant in the blast furnace process for primary steelmaking. [2] [3] [4] The demand for metallurgical coal is highly coupled to the demand for steel. Primary steelmaking companies often have a division that ...
A coking factory or a coking plant is where coke and manufactured gas are synthesized from coal using a dry distillation process. The volatile components of the pyrolyzed coal, released by heating to a temperature of between 900°C and 1,400 °C, are generally drawn off and recovered. There are also coking plants where the released components ...
An air flow meter is a device similar to an anemometer that measures air flow, i.e. how much air is flowing through a tube. It does not measure the volume of the air passing through the tube, it measures the mass of air flowing through the device per unit time, though Thus air flow meters are simply an application of mass flow meters for the ...
The rank of coal is correlated with its geologic history, as described in Hilt's law. In the ASTM system, any coal with more than 69% fixed carbon is classified by its content of carbon and volatiles. Coal with less than 69% fixed carbon is classified by its heating value. Volatiles and carbon are on a dry mineral free base; heating value is ...
FCI operates a NIST flow calibration laboratory with 19 precision flow stands. FCI utilizes these precision flow stands to flow actual gases and reference fluids matched to the temperature, process conditions, and line size of individual customers' flow meter applications. The company has subsidiaries in Tilburg, Netherlands and Beijing, China.
