Vegetable oil plant should be designed for the wastewater treatment process wastewater generated at different volume and water quality, national and provincial environmental standards for the design basis, the choice of appropriate processing methods and equipment, to invest in a low, stable, impact resistance, flexibility and ease of operation and management.

With straw after straw briquetting machine vegetable oil plant
This is not necessarily long straw briquette combustion , the combustion in different ways and at different firing burner which is different , with the weight of the coal and straw vegetable oil plant can not be said that there are also longer and the burner combustion related .
The current combustion mode are the following :
A layered burning
Stratified combustion , also known as the fire bed combustion , only for solid fuel combustion is the main way NMB briquetting machine boilers . Stratified combustion adapt to a wide range, but mixed with the combustion air is bad, the combustion reaction is slow, sometimes black smoke .
Second, the suspension burning
Suspension burning combustion chamber , also known as fire , applicable to solid , liquid or gaseous fuel . Is the primary combustion method and medium-sized boilers . Suspension without grate combustion , NMB oil mill plant and air contact area, rapid fire , high burnout rate, combustion efficiency and thermal efficiency , enabling automatic control. However, vegetable oil plant equipment and more complex systems , energy consumption .
Third, fluidized bed combustion
Burning material is crushed into particles less than 2mm into the furnace after the air from the hood into the air distribution plate , rolling up and down the coal , was similar to the liquid boiling burning. Fluidized bed combustion equipment heat storage capacity , strong combustion reaction . In this way the combustion temperature below 900 degrees , NMB feed mill greatly reduce the serious carcinogen formation of nitrogen oxides , and easy to take measures for desulphurization , and conducive to environmental protection , the great development prospects.
Above four combustion mode, straw briquetting machine can be used to block out the layered straw burning , suspended burning equipment.
