Yield important.Yellow phosphorus burning is insufficient, may cause the color of phosphoric acid product yellow, readily oxidizable substance partially it is exceeded,
The problems such as chimney emits tobacco, the sour glue in combustion furnace bottom is excessive.
At present, in the prior art, it is many using liquid phosphorus combustion method production thermal phosphoric acid.Use high-pressure pump or compressed air
By after the molten phosphorus that phosphorus-melting groove is melted is transported to head tank, combustion furnace burning is flowed into high-pressure injection.Though yellow phosphorus is with height in the method
The mode of pressure injection enters combustion furnace, and dispersiveness preferably, but is in still droplet-like into the yellow phosphorus of combustion furnace, and it is difficult to reach with air
To the state fully contacted, and then the combustion efficiency of yellow phosphorus is have impact on to a certain extent.
