1. What is straw pellet fuel?
Straw pellet fuel refers to any granular fuel made of crop straw, which is called straw pellet fuel. The straw used in straw pellet fuel mainly includes wheat straw, corn straw, rice straw, cotton straw, etc., which is an environmentally friendly boiler fuel that is pressed at high temperature through a straw pellet machine.
2. Features
(1)Grain shape
The exterior of straw pellet fuel is cylindrical, with a smooth surface, slightly glossy, density >1, gray-yellow color, outer diameter 6 to 10 mm, and length 10 to 36 mm.
Straw pellet fuel refers to any granular fuel made of crop straw, which is called straw pellet fuel.
(2)Casual value
The heat emitted by unit mass of straw pellet fuel when it is completely burned becomes the calorific value of this fuel. Due to the high density of straw particles, the combustion efficiency is high. The central temperature can reach 1100℃ during combustion, the calorific value can reach 3700-4000 kcal per kilogram, the density is 1.1 tons per cubic meter, and the ash content is <8%. In comparison with the same coal and petroleum, it also shows its unique advantages.
3. High firepower and low residual ash
Straw pellet fuel has the characteristics of being undeformed or disintegrated during combustion and being easy to burn. Due to high-pressure molding, the particle density is high, so it is flame-resistant, has strong firepower and high temperature. With reasonable air distribution, sufficient oxygen supply can be achieved, and secondary combustion is free of pollution and high combustion efficiency. Compared with coal, the residual ash collected can be returned to the field directly. It is an ideal clean energy for use as potassium fertilizer.
4. Clean and environmentally friendly
Use straw pellet fuel, clean, environmentally friendly and less pollution. When straw pellet fuel is burned, the dust discharge concentration is less than 40 mg per cubic meter, and the sulfur dioxide emission is 1/15 of coal and 1/7 of fuel oil. Therefore, the use of straw pellet fuel is an effective way to improve air quality and avoid greenhouse effects. Straw pellet fuel has the characteristics of being undeformed or disintegrated during combustion and being easy to burn.
5. Easy to transport and easy to store
In addition, straw pellet fuel is easy to transport and easy to store. Since the volume of straw is compressed by nearly 9 times after being made into pellets, it is convenient for transportation and storage, greatly reducing storage and transportation costs. Straw pellet fuel is not prone to mildew in summer, is fire-proof, flame-resistant, and is easy to store for long-term. It can be used as a reserve fuel in disaster prevention and disease prevention.
