Chamber for Supply Reheat Steam in System for Drying Coal using Reheat Steam

The present invention is a reheat steam to the coal to be fed to the transfer device which via a differentiator in a multi-stage dryer transfer and load the coal pile of a plurality of transfer plate surface from coal quantitative feeder, rotating and falling drying the coal using a reheat steam as to ensure that the injection at a constant pressure of the reheat steam supply chamber for improving a drying efficiency, and spaced apart by a pair of first pair of first a certain distance driven sprocket of the drive sprocket of being fastened to the first chain, respectively, a first chain and a plurality of first transfer plate hinge coupled between the first drive sprocket and the first image side is connected between the driven sprocket a first pair of first guide for supporting horizontally the upper first transfer plate below the chain rail is installed and the first number of the lower first transport plate under the lower first chain is connected between the drive sprocket and the first driven sprocket Supporting a pair of second guide rails are installed in that, a first vapor chamber for injecting a reheat steam supply in the re-opening below said upper first chain is provided, fed from the re-opening under the lower first chain and a second steam chamber for injecting a reheat steam installation, the first off-gas chamber for collecting exhaust gas on the upper first chain is provided, the first coal and a second off-gas chamber for collecting exhaust gas on the lower first chain installed dryer; And the two pairs of the second pair of second driven sprocket and the drive sprocket is connected to each of the second chain and spaced apart by a predetermined distance, a second and a plurality of second transfer plate hinge coupled between the chain and the second the lower side is connected between the drive sprocket and the second below the upper second chain coupled between the driven sprocket, a pair of third guide rails for supporting horizontally the upper second transfer plate is provided, the second drive sprocket and second follower sprocket claim 2 is a pair of fourth guide rails for supporting horizontally the lower side second transfer plate placed under the chain, the third steam chamber for injecting a reheat steam supply in the re-opening below said upper second chain is provided, wherein the lower side and a fourth vapor chamber installation for injecting the reheat steam supply in the re-opening under the second chain, the third off-gas chamber for collecting exhaust gas on the upper second chain is provided, on the lower chain A second coal dryer the fourth off-gas chamber for collecting the exhaust gas is installed, and the each of the first transfer roller between the first center of the first chain transfer plate on both sides being hinged, the first transfer roller left and right the first auxiliary rollers are respectively hinged to the side of the first transfer plate, the second transfer plate on both sides the center and each of said second transfer roller between the second chain are hinged, and the second transport roller left and right a second auxiliary roller and the second feed are respectively hinged to the side plate, the second first guide which is rotatably supported by the lower first direction the first transfer plate separated from the guide rail is raised bar first drive sprocket at the top a second guide bar for supporting a first driven sprocket being installed along the side to the bottom, rotated in the first direction by the upper first transfer plate separated from the first guide rail is lowered Along the side surface from the bottom it is installed to the top, and the third guide bar is provided along the side surface to the bottom in the second drive sprocket top of the first support 4 rotates in the lower first direction a second transfer plate separated from the guide rail is raised, wherein the location of the fourth guide bar 2 along the side in the driven sprocket the lower and includes being installed to the upper, the first transfer plate which supports the rotation in one direction, the upper second transfer plate separated from the third guide rail is lowered a, and the facing surface includes a coal quantitative feeder for feeding a fixed amount of coal, and to input the primary drying coal from the first coal dryer in the second coal dryer in the coal drying device using a reheat steam formed so that the secondary drying It said first steam chamber, the second steam chamber, the steam chamber 3 and the fourth re-heat syndrome generated in the re-opening on one side steam chamber Connecting the steam supply pipe for supplying a group each of which is said first vapor chamber, the second steam chamber, the third steam chamber and a fourth vapor chamber inner upper first perforated plate for steam distribution formed ball a plurality of first steam injection through each coupling is provided to ensure that the injection is first vapor minutes reheat steam at a uniform pressure through the injection port. The invention is to be injected from the multi-stage coal drying to the coal surface and inside the reheat steam at a high temperature at a uniform pressure, the feed and load the coal pile of a plurality of the transfer plate, made to rotate and fall smoothly operation of the transfer plate so as to feed improves the drying efficiency of the coal, it is possible to minimize the coal dust formation during transport in compact implementation of the coal drying device while feeding the coal stacks on the plurality of the transfer plate, with increased reliability in accordance with the operation of the coal drying device plate by whereby the moisture contained in the coal as a reheat steam of high temperature is injected through the through hole through a plurality of dispersion and equalizing the density of the coal pile to be transported in order to dry efficiently in and flattened contact to the reheat steam at a high temperature facilitates the coal particles so that the use of the thermal power plant fuel And to remove the remaining moisture in the carbon inside and outside to prevent the incomplete combustion of the coal, which will enable better use of lower coal demand less improve the stability of the coal supply.
