It is well known that China is an agricultural country, in the rural areas, crop straws can be seen everywhere. How to deal with the crop straws in the farm has become a headache for the farmers. Most of the straws are burned directly as agricultural wastes in the wild. But now, they have a new and important usage. They can be processed into straw pellets as a new biomass fuel by the straw pellet mill.
Advantages of Straw Pellets as Fuel
Straw pellets are featured by low flash point, high calorific value, low moisture content, long burning time. Compared with original straw, the final pellet fuel is one thirtieth in volume and the density is increased greatly, which makes the straw pellets easy to be transported and stored for a longer time.
Besides, no additives are added when pelletizing. Therefore, zero carbon dioxide and sulfur dioxide emission when burning the straw pellets. The ash from burning the pellets can be used as the mineral fertilizer for plant growth. The raw materials for straw pellets are abundant in nature. In addition to the straw, other materials such as halm, leaf, corn bran and sawdust can also be used as raw materials. Compared to wood pellets, the cost of straw pellets is substantially cheaper. Straw pellets are also the ideal choice for animal bedding and animal feeding.
Wide Application of Straw Pellet Mill
1. Rural Construction.
The crop straws are usually piled up around the house, which is not only unhygienic, but brings a great security risk. In the construction of new rural area, this situation must be changed. Therefore, the straw pellet mill can solve the problem of storage and add the value of straws.
2. Energy Conservation and Environmental Protection.
Along with the development of rural economy, the coal and gas have replaced straws gradually. Most of the straws are burned directly, which have lead to a number of fires and polluted the environment seriously. After pelletizing, the pollution problem is solved, meanwhile, bringing benefits for the farms.
3. Livestock Industry Development.
After pelletizing, the straw pellets can be used as animal feed, which have strong palatability and various kinds of nutrient elements.
4. Conservation of the Natural Environment.
In order to protect the natural environment, some areas adopt ungrazed policy. The livestock have to be bred in captivity. In the north, heavy snow often brings losses to the breeding industry. Processing the straw into pellets is the best way to store the feed.
