Coal gangue is one of the industrial solid wastes that may harm the human body through the ecosystem for a long time. Using coal gangue in geopolymer preparation can effectively reduce cement output and meet the sustainability requirements. In this paper, the physical and chemical characteristics, including the heavy metal content, of coal gangue from different producing areas are described ...
A trajectory imaging based method for measuring the velocity and diameter of coal particles was presented. By using an industrial chargecoupled device (CCD) camera and a low power semiconductor laser, the images of coal particles under relatively long exposure time were recorded and then processed to yield both the velocities and sizes. Fundamental research on this method with special ...
On one hand, the thrust without the addition of the coal powder is N, which is increased to N by the addition of the coal powder. On the other hand, the thrust of the PRDE is increased from N to N with the increase of the coal powder supply.
Coal dust is a finepowdered form of coal which is created by the crushing, grinding, or pulverization of coal rock. Because of the brittle nature of coal, coal dust can be created by mining, transporting, or mechanically handling it.. Grinding or pulverizing coal to a dust form before combusting it improves the speed and efficiency of burning, which makes the coal easier to handle.
Lignite: Lignite coal, aka brown coal, is the lowest grade coal with the least concentration of carbon. Lignite has a low heating value and a high moisture content and is mainly used in electricity generation. The precursor to coal is peat. Peat is a soft, organic material consisting of partly decayed plant and mineral matter.

Hand loaders owned their own implements, but paid tool maintenance fees for the operation's blacksmiths and purchased blasting powder from the company. Hand mining required skill, and young miners usually served an apprenticeship under a relative. Lying on their sides, miners first used a pick to undercut the coal three to four feet deep.
The ironmaking blast furnace plays a dominant role in an integrated steel work in terms of energy consumption and CO 2 emission. Pulverised coal injection (PCI) technology is widely used in this process [1], [2].In this operation, coal powder is injected with gas into the blast furnace via a lance through a tuyere, and combusts in the raceway cavity and then in the surrounding packed bed of ...
Blind coal: Blind coal is in powder or little bulk shape, in black color with shining metallic luster. The coal has low impurity, high content of fixed carbon (over 80%); the coal has low volatile component of lower than 10% and high ignite point. When burned, coal soil should be added to reduce thermal power.
