How big is the difference between natural gas and pellets? Now let’s comprehensively analyze and compare the differences between the two from various aspects such as combustion value, economic value, and renewability.

Natural gas PK pellets

First of all, the combustion value of natural gas is 9000 kcal, and the combustion value of pellets is 4200 (the combustion value of different pellets is different, the combustion value of crop straw is around 3800, and the combustion value of wood chip pellets is around 4300, so we take the intermediate number).

Natural gas is 3.6 yuan per cubic cube, while the combustion cost of one ton of pellets is about 900 yuan (calculated based on 1,200 yuan per ton of pellets).

Let's assume that a ton of boilers costs 600,000 calories for an hour, so the natural gas and pellets 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 pellet machine of wood chip granulator has won wide recognition as a new type of pellet fuel for its unique advantages. Compared with traditional fuels, it not only has economic advantages but also environmentally friendly benefits, and meets the requirements of sustainable development. The pellet fuel after forming has a large specific gravity, small size, combustion-resistant, and easy to store and transport. The volume after forming is 1/30~40 of the raw material volume, and the specific gravity is 10~15 times the raw material (density is: 1-1.3). The calorific value can reach 3400~5000 calories, which is a solid fuel with highly volatile phenols.

Secondly, natural gas, like many fossil fuels, is a non-renewable resource. It's gone after use. Biomass pellets are made of straw and agricultural and forestry waste into corn stalk pellets. Even bark, palm, fruit pom, etc. can be processed into pellets. Straw and trees are renewable resources. So in layman's terms, wherever there are straw and wood chips, there are pellets.

The carbon dioxide released when the pellets burn is equivalent to the carbon dioxide emissions released by plants during photosynthesis, which can be almost negligible. There is no question that it will cause pollution to the atmosphere. In addition, the sulfur content in the pellets is almost less than 0.2%. Investors do not need to set up desulfurization devices, which not only reduces costs, but also helps atmospheric protection!
