Sweden biomass pellet fuel sector evaluation<br>
Sweden is among the world's biggest wood pellet fuel manufacturer and also customer. It's wood pellet manufacturing modern technology, sector plan, and market design are prominent. In this flow, I will do extensive analysis on Sweden biomass pellet fuel industry, as well as exercise some valuable experiences.



Introduction

In the 1970s, lots of nations have made plans to promote biomass energy as a method to manage energy situation and also setting contamination. Since then, biomass power industry has developed rapidly, and the technology maintain boosting.



Because of the absence of mineral sources, Sweden's economic situation endured terrific loss in last century. To ensure nationwide power safety and security, Sweden federal government strive to create renewable energy.



Biomass pellet fuel has the functions of high burning effectiveness, low ash web content, zero carbon emission, easy transportation, which has been popular in Europe as well as North America. With plentiful forestry sources, Sweden pay much attention to the growth of biomass pellet fuel. Sweden uses up 20% of the globe's biomass fuel usage, which grows up at the speed of 8-10%.



Sweden forestry sources and biomass materials

Sweden has abundant forestry resources. The forest covers 64% of the acreage, with 51% possessed by individuals, 24% by huge wood firms, and also 25% by nations and also other public organizations. Besides, the forestry expands by 100 million heaps each year, and the logging amount is 92.4 million bunches. The major forestry sectors are wood processing, paper processing, and power wood. The wood products for making biomass energy mainly originated from the 3 industries above, regarding 23.48 m3.



Resources of wood pellets

Of the raw materials for making wood pellets, wood shavings take up 53%, sawdust 35%, and wood chips 5%, others (barks, farming residues, power forestry) takes up 7%. Some tiny wood pellet manufacturing facility are constructed base upon chipboard, furnishings and sawdust mills.



With even more business engaging in biomass fuel production, the competition on the raw materials come to be more strong. As the crop straws in Sweden are in scattered circulation, they are tough to collect and also refine. So some manufacturers and also institutes are creating new materials like peat as well as energy plants.



Wood pellet producing modern technology and tools

The pellet molding innovation has actually grown in Sweden. Nowadays, it has accomplished commercial as well as market manufacturing. The production procedure includes high automation, requiring much less operators. The picture listed below showed the wood pellet production process.



Drying out: typically, the wetness material of sawdust is around 50%. A drum dryer can reduce the wetness web content to 9-12% so that it is gotten making pellets.

Crushing: the size of resources must be under 5mm. They require a hammer mill to lower the dimension.

Conditioning: add high-heat heavy steam to the raw products and soften the cellulous in it. homemade feed pellet machine than half of the pellet fuel makers have conditioning procedure in manufacturing.

Pellet molding: many wood pellet manufacturing facilities utilize vertical kind ring pass away pellet machine. The manufacturing capability of one device is 2-4ton/ h. small fish feed pellet machine of ring die is 2000-3000h, while the roller can last 1000-1500h.

Cooling: the wood pellets extruded out from the pellet maker are at the temperature of 100 ℃. Pellets under this condition are simple to break as well as bothersome for transport. A counter-flow colder can cool off the wood pellets in a moderate means.

Packaging: the cooled pellets need to be categorized and packaged according to customers' need. Little bags are 16kg, big bags are 900kg. For big consumers like nuclear power plant, the wood pellets are carried by vehicles as well as ships wholesale.

Biomass pellets category and also application

In 1999, Sweden federal government released the standard of wood pellet fuel, in which they are identified right into 3 courses. The first class has top quality. They can be made use of in residential little burners as well as stoves.The second and also third do not have excellent quality. They are made use of by big industrial consumers.




Currently, 57% of the wood pellet fuels in Sweden can meet this standard. Several of them can fulfill the EU requirement, others are not produced according to this criterion.



Wood pellet fuel can be used in little boilers, medium-scale and large-scale home heating supply center and also power plant. Presently, Sweden has 60% of wood pellet fuel for little and also medium home heating boilers and regional home heating supply center, and 40% for large heating supply facility and co-firing power plant.



From the 1970s to the 1990s, Sweden regional heating plant take on coal to change oil. After the pass of carbon dioxide exhaust tax obligation, these heating plant look to biomass fuel from coal. In the last years, the amount of biomass fuel for heating grows from 1.1 PJ to 57PJ. Presently, about 400 regional home heating plant has actually adopted wood pellet fuel.



Because the mid 1990s, residential wood pellet sector has made excellent progression. In wood stove pellet making machine , making use of domestic home heating wood pellets proliferates. Presently, Sweden has 200,000 families utilizing wood pellet boilers, 40,000 family members using wood pellet ovens.



Sweden biomass power advancement objective as well as plan

To advertise the continual growth of biomass energy, Sweden has actually made a collection of legislations and plans. To make sure the carry out of these policies, the federal government likewise made several practical supervision actions and necessary industry requirement.




Sweden not only satisfy the obligation stipulated Kyoto Method that cut greenhouse discharge by 8%, however likewise established its very own advancement goal of biomass power. In 2006, the Minister for sustainable development division asserted that Sweden will completely utilize biofuels and stop utilizing oil, and end up being the very first nation that completely rely on renewable resource.



By 2020, Sweden will boost its percentage of renewable energy to 50%, the usage ratio of renewable resource in transportation market to 10%, power performance by 20%, as well as cut the discharge of greenhouse gas by 40%.



Wood pellet fuel incentive policy

Sweden has actually performed high rate purchase, investment subsidies, tax reduction and exception, quota system and also various other biomass energy motivation policy.



Because 1975, Sweden invests 36 million Euro from government budget to sustain biomass innovation growth. From 1997 to 2002, the government supplied 25% financial investment subsidy to biomass cogeneration jobs. From 2004-2006, the federal government supplied 1350 Euros for locals who use biomass heating unit.



Sweden normally lay high tax on fuels, energies, CARBON DIOXIDE, SO2, etc. To advertise the growth of biomass power, to spare all tax obligations on biomass tasks. In 1991, Sweden government starts to lay tax on carbon dioxide emission, which makes the price of oil and fossil fuel increase. So many heat supply center and nuclear power plant changes from fossil fuel to biomass fuel.



To encourage the nuclear power plant to utilize biomass energy, Sweden federal government introduced electric power quota system. This policy needs the power distributors to have particular portion of power generated by renewable resource. For each 1MWh power, the government will certainly offer tax alleviation based upon the biomass power amount.



Sweden wood pellet fuel melting gadget

Sweden wood pellet shedding innovation remains in the leading placement. There have actually been over 20 pellet burner producers, over 50 sorts of wood pellet boilers, 120,000 collections of pellet boilers, 20,000 collections of pellet cooktops. As there are still numerous households using electric home heating, the pellet boilers have huge capacity.



Sweden pellet burning equipment has main heating central heating boiler and also biomass cooktop 2 types.



Central home heating central heating boiler can be used in 1 or even more family members. The thermal send with water. The powers are 10-40kw, which can be adjusted by 30% -100% according to needs. The central home heating boilers additionally has 2 types. The consolidated boiler is attached by a pellet burner and also a conventional central heating boiler. The central heating boiler can connect with various burners. The integrated boilers are mainly imported from Austria and also Germany, some produced by domestic suppliers.



Biomass ovens or heater

Biomass stoves likewise has 2 kinds. Independent pellet stove and also Chimney item type heating system. The former on is a lot more popular. The independent pellet stove has a pellet stock bin within, which can hold wood pellets for 2-day usage.



Biomass pellet stove can understand automatic dental filling and also burning. Based upon different feeding approach, pellet cooktops has leading feed, lower feed and horizontal feed 3 types. Leading feed pellet cooktops are the most prominent. Owing to high convenience and cleanliness, tiny pellet ovens sell well over the last few years.



Functions of Sweden biomass fuel industry

Sweden has rich forestry sources and also bountiful forestry waste, which come to be the primary resources for biomass pellets.

Sweden wood pellet sector has been fully advertised. Many manufacturers are large and average companies, with fully grown modern technology. Small wood pellet manufacturing facilities are mostly build on chipboard, furniture and also saw mills.

The government has made detailed legislations and plans to drive the wood pellet production. This is why the wood pellet industry creates rapidly given that the 1990s.

Criterion for wood pellet fuel maintain enhancing. In the 1990s, Sweden published the standard for wood pellets, as well as measured the technique date of pellet fuel and also burners.

Fully grown burning technology and devices. In recent years, Sweden's manufacturing of pellet boiler and pellet home heating cooktops keep enhancing.

Perfect quality control system. Sweden government specified that the wood pellet fuel as well as burning equipment must acquire third-party screening certifications before entering the marketplace.



Final thought
