5), the separation water in steam-water separation tank (1-3) is entered back into saturated steam generator (1-1) by return pipe (1-7), is followed
Ring uses；
6), after high temperature sludge surface blackening generates temperature drop, the slag car (2) is pulled to tunnel type waste heat again and returned by slag car traction device (3)
Outside the left side of receiving apparatus (1), the slag car (2) is wheeled while mobile to turn over slag device (4) operating for the high temperature sludge progress in the slag car (2)
Slag is turned over, so that slag blanket central high temperature slag is turned to surface and discharges higher heat；The slag car (2) is retracted by slag car leading-in device (3) again
Continue to take heat in tunnel type waste-heat recovery device (1), it is wheeled while the slag car (2) are mobile to turn over slag device (4) reversion to high temperature
Slag progress is secondary to turn over slag；
7), it is wheeled turn over slag device (4) rotation when, cooling device (4-5) atomized water spraying cooling turns over slag wheel (4-1), turn over slag wheel (4-1)
A small amount of dust is generated when turning over slag to be siphoned away by dust excluding hood (4-6), and pollution of the dust to surrounding enviroment is avoided.
