How to improve combustion efficiency of beer spent grains' dryer? Looking for the energy saving and high quality spent grains' drying equipment, in addition to the selection of suitable models, should also be better for the actual operation of the equipment, to use the best technology, provides the least amount of fuel to achieve the best drying effect, which is able to guarantee the equipment bring the maximum benefit of the foundation, years of experience shows that three factors influence the dryer drying efficiency.
First, to reduce the drying machine cost utility, we first thought should be used for burning coal provides a heat source drying machine, the minimum amount of coal material is that we reduce the cost of a breakthrough, how to make use of the amount of coal material at least, and keep the drying effect of drying machine is not decreased, after the research we get the particle size of pulverized coal, coal seam thickness, the amount of air blown into the three factors of pulverized coal combustion plays an important role, first is the particle size of pulverized coal, pulverized coal and air time when the finer the particle size of the contact area will be greater, the combustion will be strong, under normal circumstances we will coal the control of particle size between 0.05mm-0.08mm, this size range is one of the most appropriate range of use. Compared with anthracite, because of its hard texture, we can appropriately increase the range of pulverized coal particle size. Generally, it is more suitable for 0.08mm.
Second, then is about the problem of coal seam, coal burner when the dryer is thick, coke layer for combustion is thick, the content of combustible gas escaping gas content will be increased, excessive air quantity is less when the combustion gas is not completely burned, it will cause the coal combustion is not full, waste phenomenon, when the coal seam is thin, the ventilation is relatively smooth, but the ventilation is not uniform, resulting in the emergence of the coal seam, the seam is extremely easy to cause the accumulation of heat is reduced, is not easy to form high temperature combustion layer, and is not conducive to coal burning.
Third, finally is blown into the air, how much air into the drying machine inside the combustion chamber for material sufficient combustion also plays a very important role, blowing air to cooperate with each other to make the material fully burning, when the coal seam thickness is large, the amount of air into the need is greater also, under normal circumstances we will put the coal seam thickness is controlled in the range of 100mm-200mm, so the coal combustion will be more complete.
If the sand dryer equipment is being produced, it can be produced according to the above method, which can largely improve the efficiency and improve the utilization ratio of resources.
