Pulverised Coal - an overview | ScienceDirect Topics
Pulverized coal can be used as a reducing agent by injecting it through the tuyeres. Coke has been replaced up to 250 kg/THM with pulverized coal [26]. Coals for PCI are usually cheaper noncoking thermal coals. Important properties of the coals are: • content of volatiles and moisture • stone composition (S, P, alkalis, ash) •
METHOD OF DETERMINING THE DEGREE OF COMBUSTION OF ...
It is proposed that the completeness of combustion of pulverized-coal fuel injected into the hearth of blast furnaces be determined by petrographic analysis of the content of unburned coal particles in the top dust and slag and stone analysis of the dust and slag. Keywords: coal, pulverized-coal fuel, top dust, sludge, slag, blast furnace.
Coal dust - Wikipedia
Coal dust is a fine powdered form of coal, which is created by the crushing, grinding, or pulverizing of coal. Because of the brittle nature of coal, coal dust can be created during mining, transportation, or by mechanically handling coal.It is a form of fugitive dust.. Grinding coal to dust before combusting it improves the speed and efficiency of burning and makes the coal easier to handle.

Effects of moisture in coal on pulverized coal …
01-08-2001 · The test fuel was Newlands bituminous coal. Its properties are shown in Table 1, and it originally contains 2.2% moisture.To investigate the effects of the moisture in the coal, Kimoto et al. imitatively increased the moisture content by injecting the steam generated by a steam-generation apparatus into the primary air. It should be noted that, contrary to the introduction of coal moisture ...
Experimental investigations on the roles of …
01-09-2014 · Explosion behaviors of coal dusts were systematically investigated to focus on the roles of moisture in dust explosion. It is found that, when the moisture content is lower, the explosion parameters (P ex, (dp/dt) ex and MEC) basically keep a linear relationship with the moisture content.With the further increase of moisture content, the moisture would gradually agglomerate …
