NAME :- NOZZLES

MOC :- SA351,   GR:- HK 40 & Many other.

WORKING :- Working at high temperature .

DETAIL:- A Nozzle in accordance withthe present invention is used advantageously in heat engineering to bring fluidizing gas to a furnace of a fluidized bed boiler. According to a most preferred embodiment, Nozzles are used for removing from a furnace soild particles drifted to the bottom of the furnace. Gride nozzlecomprises a nozzle chamber & a nozzle channel ending to a blow openingg of the nozzle, which nozzle chamber and nozzle channel are limited from above a lid and protecting cover.  

Air nozzle being provided with a plurality of distributior so arranged to supply additional fluidizing air, the outlet path of fludising air is designed for the air to flow at high velocity without hindering the path of fuel flow fule feed nozzle the height of nozzle being designed to minimize erosion of nozzle,Pitch of nozzle being arranged to supply fule uniformly across the bed and solid fule outlet of nozzle being designed to obtain drop in pressure in pneumatic transportation pipes.
