Raw material management measures

According to the suggestions of our engineers, customers should conduct strict daily management of raw materials entering the factory:

1. Customers need to have certain control and inspection capabilities, and can independently control and inspect each batch of raw and auxiliary materials entering the factory, inspect the production workshop, observe whether the raw materials are clean, whether glue, paint, etc. have not been removed, and those that do not meet the requirements will not be allowed to enter the factory.
2. Keep records of all raw and auxiliary materials entering the factory, retain their purchase and sales contracts, and the quantity of items should be clearly stated in the contract. Require raw material suppliers to promise that the raw materials they provide do not contain oil stains or organic coatings (such as glue, paint, etc.).

The raw materials of the USA wood pellet plant project, such as wood chips, wood, stumps, and wood scraps, are all combustibles, which will cause combustion when exposed to open flames. If there are sparks or fire in the wood chips, wood, and stump yards, and there is sufficient oxygen, dry and windy weather conditions, it is easier to cause a fire. Therefore, the raw material storage site should do the following:

• The raw material storage site must be a closed facility, and must have rain protection, sun protection, anti-seepage, dust prevention, anti-scattering and fire prevention measures.
• The wood chip, timber, and stump storage areas and production and processing areas should be arranged separately. The wood chips, timber, stumps, and timber scraps in the storage and production areas should be grouped and stacked according to categories, and necessary fire protection distances should be left.

How to build a wood pellet production line in the United States?

In the United States, wood pellets are mainly used for heating and power generation, especially in the residential and commercial building sectors. Government incentives and environmental regulations have also promoted the use of biomass energy. Therefore, wood pellet processing has a very good market prospect in the United States.

The basic steps to build a wood pellet production line include raw material preparation, equipment selection, production line layout and operation training.

1. First, you need to prepare the raw materials. The raw materials of the wood pellet production line include waste wood, branches, straw, scraps, building templates, wooden pallets, furniture scraps, boards, straw, garden trimmed branches and leaves, waste wood strips, and wood processing plants. The remaining wood. These raw materials can be used as raw materials for the crushed wood pellet molding machine to press pellets after crushing.
2. The next step is equipment selection. The equipment needed to process biomass pellet fuel includes crushers, extruders, and dryers (optional equipment, which can be physically dried). Small production lines can choose equipment with an output of 2 tons or less, while large production lines can reach a scale of more than 10 tons per hour. When purchasing equipment, you can consider professional manufacturers such as RICHI Machinery, which provide customized equipment solutions.
3. Then there is the production line layout. The production line layout needs to take into account the process flow of raw material transportation, crushing, drying and granulation. The entire production process can be fully automated from crushing, crushing, drying to granulation to ensure efficient operation.
4. Finally, there is operation training. Operators need to undergo professional training to ensure that they can operate the equipment proficiently and ensure the normal operation of the production line. The training content includes equipment operation, maintenance and troubleshooting.

Through the above steps, a wood pellet plant can be successfully established to achieve efficient use of raw materials and large-scale production of products. In addition, the cost of building a wood pellet production line mainly includes equipment purchase, plant construction and operation costs.

U.S. Wood Pellet Exports

The first development of wood pellet fuel was due to energy shortages in the United States in the 1870s. The raw materials mainly come from wood waste from furniture factories, paper mills and other factories. Just like propane or natural gas, the energy obtained from burning wood pellets can replace electricity, fuels for fireplaces or stoves, and fossil fuels. At the same time, stove appliances supporting biomass pellets are also diverse.

In the United States, small trees cleared from forests, non-commercially valuable wood, trees that do not meet the requirements of lumber, decayed wood, recycled waste wood, etc., felling residues, trees that died from pests and diseases, processing residues, construction sites The waste wood from above can be used in the wood pellet manufacturing.

In order to save natural gas and oil, and reduce carbon dioxide and sulfur dioxide emissions, the United States vigorously advocates the use of wood pellet fuel. This model has been promoted throughout the country. Power generation and heating are gradually replaced by wood pellet fuel. Ten years ago, the U.S. wood pellets were only for domestic use. Today, countries such as the United States and Canada have become the countries that export the most wood pellets.

The UK remained the largest importer of U.S. wood pellets through August 2020. The 3.8 million metric tons imported, representing 79% of total U.S. volumes, was a 9.3% year-over-year increase. Export volumes to the UK are expected to continue to rise with the completion of MGT Power's 299 MW CHP facility though construction has been delayed as a result of the coronavirus pandemic.

U.S. export volumes to the Netherlands continued to increase; year-over-year volume more than tripled, reaching 381 thousand metric tons through August. For the year, the Netherlands was the third largest importer of U.S. wood pellets with 7.9% market share. As noted, the future of the Dutch market is in question as the government pledged to further reduce emissions, which may eliminate co-firing.

Wood pellet manufacturing technology belongs to the category of renewable energy. In recent years wood fuel pelletizing plant and wood fuel pellet factory is becoming a hot promising investment project. Referring to the cost of customized biomass pellet production line projects, it is affected by a number of factors.
