DREDGING SYSTEM IN COAL BUNKER

ABSTRACT

Coal is a combustible, sedimentary, organic rock, which is composed mainly of

carbon, hydrogen and oxygen.It is formed from vegetation, which has been consolidated

between other rock strata and altered by the combined effects of pressure and heat over

millions of years to form coal seams. Coal flow failure is now regarded as one of the most

important power stasion problems yet to be solved. The main problem of the coal bunker

in use is blockage. The accident of blockage has been reduced substantially through

improving design of the coal bunkers structure, whereas such incident cannot be avoided

completely only by improving the structure of coal bunker.

Dredging system for the coal bunker is design to solve the blockage problem, which

can help optimizing of the other equipment that already used in coal fire power plant.

This equipment method borrows ideas from air cannon dredging technology. The

structure of dredging system for the coal bunker is simple and the equipment is high

adaptability and safety.

Keywords: Coal bunker, blockage of coal bunker, dredging system.
