This guideline is recommended for all fossil fuel plants burning or converting to PRB coal in blended or pure amounts. It is recognized that coal-handling facilities can vary significantly in physical layout. All bunker fires are different and must be dealt with individually. There is no
The basic layout of Coal Handling Plant is shown by block diagram. (See Fig. No5) the coal is unloaded at various unloading station and transported by conveyors to crushing and screening plant via transfer house. After crushing required quantity of coal is transported to bunker via transfer house and remaining coal is stored in stockyard. The

Nov 25, 2013 Improve Coal Flow by Using Insert Technology. Coal-fired power stations rely on storing coal in large bunkers or silos. Over time, changes in the
Boilers are the largest items of plant, and in modern power stations they are suspended from a framework of heavy steel beams just below roof level. The boilers, with their ancillary plant and associated coal bunkers, comprise a very high proportion of the total load. The foundations provided are largely required to carry loads arising from the plant, the loads due to the buildings being only a
Pulverized coal storage in Bunker. Periodically a power plant may encounter the situation where coal must be stored for sometimes in a bunker, for instance during a plant shut down. The bunker, fires can occur in dormant pulverized coal from spontaneous heating within 6 day of loading. This time can be extended to 13 days when a blanket of CO2 is piped into the top of the bunker.
burning coal, a fire is already under way (Figure 2). Some plants make bunkers or silos of PRB coal inert with carbon dioxide (CO 2) when they are expected to sit idle. For this practice to be effective, the enclosure must be completely sealedespecially the bot-tom cone, because CO 2 is about 1.5 times heavier than air. The amount of CO 2 need-
After switching to low-sulfur sub-bituminous coal, Northern States Power Co. (NSP) experience several fires and an explosion in the coal storage bunkers of its two-unit, 384-MW Riverside plant located in Minneapolis, Minn. The most recent incident occurred in November 1993 when a blast rocked Unit 7s coal storage bunker.

May 13, 2020 A conveying system to feed coal from any bunker section to any fixing unit and to move coal from one bunker section to another. Inplant handling may include conveyors to transfer the coal, weigh lorries, hoppers and automatic scales to record the quantity of coal delivered to the furnace.
Coal bunkers, on the other hand, provide the means to store the fuel in a dry environment. Coal- red power plants are often equipped with both storage options. Risks Especially damp coal can auto-ignite quickly. This enormously increases the re hazard on coal stockpiles. In coal bunker, coal dust can create an explosion-prone atmosphere.
