High temperature high pressure natural circulation dry quenching coke residual heat boiler evaporator

The utility model discloses an evaporator of a high temperature and high pressure natural circulation coke dry quenching waste heat boiler; the utility model has the following technical proposal: the evaporate adopts the natural circulation mode; tubes which form the evaporator are all set to a structure in horizontal arrangement; the tubes which form the evaporator can adopt plain tubes or extended surface tubes. The evaporator in full horizontal arrangement is adopted in the coke dry quenching waste heat boiler, and therefore the heating surfaces arrangement in a silo flue is more convenient and the workload of manufacturing and maintenance is also greatly reduced; in addition, circular pylomes formed when the horizontal tubes are guided out of the silo flue are also more favorable for sealing treatment.
