Biomass particles are formed by chemically changing lignin in raw materials at high temperature and extruding through high pressure equipment. Biomass particles contain 75-85% carbon, 3-6% ash, and 1-3% water content. Biomass particles are small in size, high in density, high in purity, large in heat, and easy to store and transport. Clean and cost-effective fuel. No matter what it is, it has a storage period, so how long can the biomass pellets be stored after it is made?
Biomass particles are packed in plastic bags, paper bags or woven bags, which cannot be isolated from contact with the air. The air itself contains moisture, and the particles will loosen when they encounter a certain amount of moisture, so even if the air is dry, In the long run, the pellets also have a certain shelf life.
In short: How long biomass pellets can be stored depends mainly on the humidity of the storage environment.
In the four seasons of the year, the air is relatively dry in spring and winter, and there is very little rainfall, so the water content in the air is relatively small, and the particles do not need to worry about being damp and loose in these two seasons. In summer and autumn, there are more rainy weather, and the moisture content in the air is naturally high. In these two seasons, moisture-proof work must be done. Due to the climate in the south and the north, the moisture-proof time and storage time of the pellets will also be different, and it should be appropriate according to the location.
The ambient humidity of biomass pellets is 10% as the boundary, less than 10% can be stored for 6 months, more than 10% according to different humidity, the storage time is also different, generally 1-3 months. The storage capacity of biomass pellets is generally determined according to the actual usage, and as much as is used, storage once a month is sufficient for use, so generally there is rarely a large amount of storage. In addition, we can also process biomass pellets by ourselves. The pellet equipment is cheap and low in power, and raw materials are everywhere. Processing and supplying are not only convenient to use, but also save a lot of cost. Let's do the math. It costs about 600-800 yuan to buy one ton of pellets, and only about 200 yuan to process one ton of pellets. We can save 400-600 yuan for one ton of pellets. We use it for a long time. , then how much money do we save for ten tons and one hundred tons?
One: moisture-proof
Everyone knows that the particles will loosen when they encounter a certain humidity, which affects the effect of combustion. The air already contains moisture, especially in the rainy season, the humidity of the air is higher, which is more unfavorable for the storage of particles, so when we purchase, it is best to purchase particles packaged in moisture-proof packaging, so that no matter what the conditions are We are not afraid of storage.
If you want to save money and buy ordinary packaged biomass, it is best not to store it in the open air. If it rains, we have to move it back into the house, which is not a good thing for particle storage and handling.
Ordinary packaged biomass cannot be placed in a room casually. First of all, we need to know that biomass particles will be loose when the moisture content is about 10%, so we must ensure that the storage room is dry and there is no return of moisture.
Two: fire prevention
Biomass is flammable, no open flames can appear, otherwise it will cause a catastrophe. After the biomass pellets are purchased, do not pile them up around the boiler at will, and a special person should be responsible for checking whether there are potential safety hazards from time to time. For use at home, adults must pay special attention to supervise them, and do not cause children to be naughty and cause fires.
