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 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 seed oil extractioncombustion is the main way of small 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 , fuel and air contact area, rapid fire , high burnout rate, combustion efficiency and thermal efficiency , enabling automatic control. However, 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 wire stripping machine , 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 , can 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.
