Embodiment Construction
[0028] The specific implementation method on the 300-ton oil shale retort furnace in Huadian type is: see figure 1 , figure 2 ,
[0029] Change the cold cycle gas inlet entering into the original retort furnace (the applicant's prior application 200810228891.0, "300 tons of oil shale gas full cycle retort furnace per day") into saturated water vapor inlet 6, and install a spray nozzle at its lower part Water structure: the water inlet pipe with the regulating valve 7 is connected with the water spray pipe 8 arranged in the furnace, and the water spray pipe 8 has a water spray hole. The water of 25 ℃-80 ℃ is ejected by the spray hole of water spray pipe 8, or feeds steam from steam inlet 6 simultaneously, also can only use one; The pressure of water is 8000Pa, and steam pressure is 7500Pa. Both steam and water are obtained from the heat recovered from the waste heat boiler in the dry distillation system, without adding a new heat source. The ratio of water vapor and water c...
