Which is cheaper, the purchase price of 1 ton of finished biomass pellets produced by Shandong TONY biomass pellet machine or 1 ton of coal? Which has a higher calorific value, biomass pellets or coal? After converting a coal-fired boiler into a biomass boiler, which one is more cost-effective for generating one ton of steam?
The above three issues are commonly encountered among the customer groups that are about to engage in biomass pellets. It is necessary to clarify what advantages biomass pellets have as a new type of fuel compared with traditional fuel coal? Shandong TONY, as one of the earliest manufacturers of wood pellet machine and biomass pellet machine in Shandong, is here to answer your above questions.
A comparison between biomass pellet fuel and coal
1.A price comparison between 1.1 tons of biomass pellet fuel and 1 ton of coal.
The answer to this question a few years ago was that the price of biomass pellet fuel was slightly higher than that of coal. However, the present is different from the past. With the continuous rise in coal prices over the past two years; As for biomass pellets, as evidenced by their good appearance and high popularity, such as pine and rosewood pellets, the average market price is lower than that of coal
2. Biomass pellet calorific value vs. coal calorific value
The calorific value of coal is much higher than that of biomass pellets. The calorific value of 1 ton of biomass pellets: The calorific value of biomass pine wood pellets is 4,200-4,500 kcal/kg, while that of miscellaneous wood pellets is 3,900-4,200 kcal/kg. To further increase the calorific value of biomass pellets, biomass raw materials can be mixed with high-calorific raw materials for pelletizing, with the highest calorific value reaching up to 5,000 kcal/kg.
3. Cost comparison between biomass pellet fuel and coal for generating 1 ton of steam
Based on the calculation that 1 ton of steam requires 640,000 kcal of heat, the thermal efficiency of coal-fired boilers is 65%, and that of biomass boilers is 85%.
(1) How much coal is needed to produce one ton of steam? Calculation method: 640,000 ÷0.65= 985,000, 985,000 ÷ 5,000 =197 kilograms. Assuming the unit price of one ton of coal is 700, then 700*0.197=137.9 yuan is required
(2) How much biomass pellet fuel is needed to produce one ton of steam? Calculation method: 640,000 ÷0.85= 750,000, 750,000 ÷ 3,600 =208 kilograms. Assuming the unit price of one ton of biomass pellets is 600, then 600*0.208=124.8 yuan is required
Coal: 137.9 yuan > Biomass pellet fuel: 124.8 yuan.
The above are several comparisons that the customer group is particularly concerned about. However, the editor believes that there is no need to agonize over the choice between coal and biomass pellets now. After all, coal resources are non-renewable resources, and their long-term use has caused environmental pollution. However, our biomass pellets are a new type of clean and renewable fuel. In recent years, manufacturers engaged in the production of biomass pellet fuel have reaped huge profits by taking advantage of the favorable situation.
