Embodiment Construction
[0025] The specific embodiment of the comprehensive utilization of coal gangue pyrolysis gasification of the present invention is mainly introduced in detail below.
[0026] Part I Particle Size Control of Coal Gangue
[0027] The coal gangue is processed and crushed into a particle size of 0-20 mm, and the crushed coal gangue is dehydrated and dried within this particle size range, and the drying is sufficient and the dehydration efficiency is high, but this does not constitute a limitation on the coal gangue required by the present invention.
[0028] The second part of coal gangue humidity control dehydration
[0029] The waste coal gasification produced by coal gangue high temperature pyrolysis and water gas reaction is recovered and purified, and the hot waste gas generated after combustion of clean coal gas is used for humidity control and dehydration of crushed coal gangue pellets before being put into the furnace.
[0030] In order to keep the environment clean and ti...
