National straw industry technology alliance is established
Recently, the establishment ceremony of national straw industry technology and innovation strategic alliance is held in Beijing. The establishment of the "union" started the new journey of straw industry leading environmental governance, agricultural production, application of new energy and other areas of development during the 13th Five Year Plan.
According to the relevant statistics, the annual production of crop straw in our country is more than 800 million tons. If all of the straws are used to burn, the calorific value produced is equal to 400 million tons of standard coal; if being used as feed, it is equivalent to 200 million tons of grain. Straw contains abundant energy and large amounts of nutrients with great development potential and broad development prospect. However, due to the not perfect policy, relatively backward technical level and disconnecting of straw utilization research and promotion, the comprehensive utilization level and industrial competitiveness of straw is not high in our country, compared with developed countries. The "Union" being established is straw technology innovation demand oriented, which takes the formation of core competitiveness of the straw industry as the goal.
There are many methods for straw recycling, such as making bio fuel, straw returning, planting mushrooms, etc. among which the production of straw coal develops rapidly in recent years.
Straw coal can be made with rural corn straw, wheat straw, cotton stalks, crops straw, rice husk, peanut shell, corn cob, branches, leaves, sawdust and other solid wastes after crushing and through the compression and densification molding of straw briquette machine
. Straw coal after briquetting has small volume, large specific gravity, resistant to burning and easy to transport and storage. The volume is only 1/30 of the original straw and it is 10-15 times of the straw with the same weight. Its density is 0.9-1.4g/cm3 and the calorific value can reach 3500-5500 kcal. It is a kind of high volatile solid fuel.
Scope of application of straw coal:
Straw coal can be used to replace firewood, raw coal, liquefied gas, etc. It is widely used in living stove, heating furnace, hot water boiler, industrial boiler, biomass power plant and so on.
Economic and social benefits of straw coal:
Straw coal is a kind of new biomass renewable energy with low processing cost, large profit space and much lower than the price of coal. The more important thing is that farmers can make crop straw profitable in their own fields, increase income and create more wealth. With an investment, you would get lifelong benefit. There is a reliable guarantee for long-term and stable economic income, energy saving and environmental protection and benefits the nation and the people.
Equipment performance of straw briquette machine:
1 High degree of automation, high yield, low price and power consumption, simple operation and easy to move. Diesel engine can be used if no power facilities are available.
2 Strong material adaptability: suitable for briquetting all kinds of biomass raw materials from powder to straw with length of 55mm and the moisture content of 5--30%.
3 Electric heating function: full automatic electric heating device, the dry humidity of the material can be adjusted to solve the difficulty of blocking or not forming.
4 Automatic adjustment function of press roller: automatically adjust the pressure angle under the principle of two-way rotation of the thrust bearing, so that the material would not huddled together or block the machine so as to ensure the stability of material forming.
5 Simple operation and easy to use: high degree of automation, less labor, only three people are needed. Artificial feeding or feeding automatically by the conveyor is avaible.
The use of briquette machine
provides a green power for the development of society and economy, we believe that straw briquette machine will usher in a more broad development in the future.
Kingman boasts the best supplier and manfuacturer of straw briquette machine and biomass briquette plant.The use of straw in large-scale biomass power plants is becoming mainstream in the EU, with several facilities already online. The straw is either used directly in the form of bales, or densified into pellets which allows for the feedstock to be transported over longer distances.
