preparation example Construction
[0011] The steps of the preparation method of corn stalk biomass pellet fuel are as follows:
[0012] 1) first crush the outer soft shell of the corn stalk into mud, and grind the inner hard shell and shavings of the corn stalk into powder;
[0013] 2) Then, 5% to 10% of corn stalk inner layer hard shell powder, 60% to 65% of corn stalk outer layer soft shell mud, 15% to 20% of shaving powder, 10% to 15% of The sawdust is fully mixed and extruded into columnar particles.
[0014] The water content of the corn stalk inner layer hard shell powder is 10%-12% by mass and the particle size is <5mm; the water content of the corn stalk outer layer soft shell mud is 15%-25% by mass. The corn stalks are sweet corn, waxy corn, glazed corn or jewel corn.
Embodiment 1
[0016] First, crush the outer soft shell of sweet corn stalks into mud, and grind the inner hard shell and shavings of sweet corn stalks into powder; then mix 5% sweet corn stalk inner hard shell powder and 65% sweet corn stalk outer soft shell Mud, 20% shaving powder, and 10% sawdust are fully mixed and extruded into columnar particles. The water content of the hard shell powder in the inner layer of the sweet corn stalk is 10%, and the water content of the soft shell mud in the outer layer of the sweet corn stalk is 15%.
Embodiment 2
[0018] First, crush the outer soft shell of waxy corn stalk into mud, and grind the inner hard shell and shavings of waxy corn stalk into powder; The outer layer of soft shell mud, 20% shaving powder, and 10% sawdust are fully mixed and extruded into columnar particles. The water content of the hard shell powder in the inner layer of the waxy corn stalk is 10%, and the water content of the soft shell mud in the outer layer of the waxy corn stalk is 15%.
