With the continuous expansion of the current biomass pellet market, there is no doubt that investing in biomass pellet factories has now become a way for many investors to make money instead of natural gas. So, just how big is the difference between natural gas and biomass pellets? Now let's comprehensively analyze and compare the differences between the two from various aspects such as calorific value, economic value, and renewability.
Firstly, the calorific value of natural gas is 9,000 calories, and that of pellets is 4,200 (the calorific values of different pellets vary. The calorific value of crop straw is around 3,800, while that of wood pellet is around 4,300. We will take the middle figure).
Natural gas costs 3.6 yuan per cubic meter, while the combustion cost of one ton of pellets is around 900 yuan (calculated at 1,200 yuan per ton of pellets).
Let's assume that a one-ton boiler requires 600,000 calories of heat to burn for one hour. Then, the natural gas and particles that need to be burned are 66 cubic meters and 140 kilograms respectively.
Based on the previous calculation, the cost of natural gas is 238 yuan, while the cost of pellets is 126 yuan. This result is obvious.
The biomass pellets produced by the Zhangqiu wood pellet machine have won wide recognition as a new type of pellet fuel with their unique advantages.
Compared with traditional fuels, it not only has economic advantages but also environmental benefits, meeting the requirements of sustainable development. The formed pellet fuel has a high specific gravity, small volume, good combustion resistance, and is convenient for storage and transportation. The volume after molding is 1/30 to 1/40 of the raw material volume, the specific gravity is 10 to 15 times that of the raw material (density: 1.1-1.3), and the calorific value can reach 3400 to 5000 kcal.
Secondly, natural gas, like many fossil fuels, is a non-renewable resource. Once used up, it's gone. The raw materials for biomass pellets are crop straw and discarded agricultural and forestry materials. Even tree bark and palm fruit residues can be processed into pellets. Since straw and trees are renewable resources, in simple terms, wherever there is straw and wood chips, there are pellets.
Furthermore, we mentioned that pellets are processed products of straw. Basically, the crop straw from the fields and farmlands can all be used as raw materials for production. This is far superior to the air pollution caused by farmers burning their own straw.
According to the survey data, the carbon dioxide released when particles are burned is equivalent to the carbon dioxide emissions released by plants during photosynthesis and can almost be ignored. There is no question of causing pollution to the atmosphere. Moreover, the sulfur content in the particles is extremely low, less than 0.2%. Investors do not need to install desulfurization devices, which not only reduces costs but also benefits the protection of the atmosphere! The impact of burning natural gas on the air doesn't need me to list it in detail for everyone to know.
The ash residue left after the combustion of wood pellet machine can also be utilized. When returned to the fields, it can become good fertilizer for crops.
