1. Biomass energy
Biomass energy is the energy that green plants store in living organisms by converting solar energy into chemical energy through photosynthesis.
2. Biomass molding fuel
Biomass pellet fuel is a new type of clean fuel that uses agricultural and forestry waste as raw materials and is made into various forms (such as block, granular) through grinding, mixing, extrusion and other processes and can be directly burned.
3. Basic characteristics of biomass pellet fuel.
The diameter of biomass particles is generally 6 ~ 10 mm, the length is 4 ~ 5 times of its diameter, the crushing rate is less than 1.5% ~ 2.0%, the dry base water content is less than 15%, the ash content is less than 2%, the sulfur content and chlorine content are less than 0.07%, and the nitrogen content is less than 0.5%. The calorific value is around 3900 ~ 4800 kCal/kg (depending on the raw material).
4. Application of biomass pellet fuel in tobacco curing in China.
It is reported that China has the world's first biomass energy. The application of biomass energy in flue-cured tobacco curing shows that it can replace coal fuel, meet the technical requirements of curing, reduce the cost of curing tobacco and improve the inherent quality of tobacco. In recent years, China's Yunnan Tobacco Company has actively explored the recycling of agricultural and forestry waste based on tobacco poles, and made significant breakthroughs in the localized production of pellet biomass fuel and the replacement of coal-fired furnaces by biomass pellet burners. The goals of saving energy, reducing cost, improving quality and increasing efficiency of tobacco curing were preliminarily realized.
5. Baking effect of biomass particles.
(1) Energy conservation and emission reduction
The content of most gases and soot emitted by biomass pellet fuel after combustion is significantly lower than that of coal, and NO2 and SO2 are nearly zero emissions.
Application of biomass fuel particles
(2) Reduce work and costs. A baking technician in a coal-fired oven can manage up to 5 units at the same time, and a baking technician in a biomass oven can manage up to 15 units at the same time. According to the baking season of each oven, 15 acres of tobacco leaves are baked for 42 days (6 furnaces, 7 days per oven), and 3 workers are employed per day, at least 1 labor cost can be reduced per acre.
(3) Improve quality and efficiency. Biomass pellet fuel has higher quality, higher price and remarkable economic benefit than coal roasted tobacco leaves.
At present, TONY biomass pellet machine has been put into use in Yunnan, Guizhou, Hubei, Hunan, Jiangxi, Jiangsu and other places in China, and rows of clean and tidy biomass pellet fuel barbeque have opened the "new password" of green baking.
