Description

Cartridge-type coal storage device to reduce ignition and fugitive dust generation {APPARATUS FOR THE CARTRIDGE TYPE COAL STORAGE FACILITY FOR THE COAL DUST EMISSION AND THE SPONTANEOUS IGNITION FREE}

The present invention relates to a low coal yard for storing coal, and more particularly, to a coal storage device in the form of a cartridge for reducing the occurrence of ignition and fugitive dust.

The fuel of a thermal power plant is coal, which uses the heat generated by the combustion of coal to produce steam, and the steam turns a turbine to generate electricity. Stable supply of coal is very important in producing stable electricity, but when conditions such as natural disasters such as storms or strikes in the coal transportation industry occur, problems such as electricity production stop due to a shortage of coal, which is a power generation fuel, occurs.

In order to solve this problem, coal to be used for a certain period of time is stored and operated in a coal storage for storing coal in a power plant. In the case of domestic power plants, in general, at least 30 days' worth (500,000-600,000 tons) of coal is stored and operated. In some cases, coal may be generated with storage days exceeding 30 days.

However, when the coal is stored for a long period of time (more than 30 days), a large problem occurs in that spontaneous combustion occurs when air and moisture are in contact due to the inherent characteristics of coal. In this case, it is difficult to remove the ignited embers inside the coal pile, so that the coal must be taken out to a safe external place by either waiting for the entire amount to be burned or using heavy equipment such as a forklift, and it takes many days or more.

In addition, scattering dust is inevitably generated when handling coal, causing environmental pollution and civil complaints.
