Sweden biomass pellet fuel sector evaluation<br>
Sweden is just one of the world's biggest wood pellet fuel manufacturer and consumer. It's wood pellet manufacturing innovation, market plan, as well as market version are prominent. In this flow, I will do detailed analysis on Sweden biomass pellet fuel sector, as well as work out some helpful experiences.



Intro

In the 1970s, lots of countries have made plans to advertise biomass power as a way to cope with power situation and setting contamination. Ever since, biomass power industry has actually created swiftly, as well as the modern technology maintain improving.



As a result of the lack of mineral sources, Sweden's economic situation experienced wonderful loss in last century. To ensure nationwide energy safety and security, Sweden government strive to develop renewable energy.



Biomass pellet fuel has the attributes of high burning performance, reduced ash material, no carbon emission, easy transport, which has actually been preferred in Europe as well as The United States And Canada. With bountiful forestry resources, Sweden pay much interest to the advancement of biomass pellet fuel. Sweden uses up 20% of the globe's biomass fuel consumption, which grows up at the speed of 8-10%.



Sweden forestry resources as well as biomass products

Sweden has plentiful forestry resources. The forest covers 64% of the land area, with 51% had by people, 24% by large wood firms, as well as 25% by nations as well as various other public organizations. Besides, the forestry expands by 100 million bunches every year, as well as the logging quantity is 92.4 million heaps. The major forestry sectors are wood processing, paper handling, and also energy wood. The wood materials for making biomass power generally come from the 3 markets above, regarding 23.48 m3.



Raw materials of wood pellets

Of the raw materials for making wood pellets, wood shavings occupy 53%, sawdust 35%, as well as wood chips 5%, others (barks, farming deposits, energy forestry) occupies 7%. Some tiny wood pellet factory are developed base on chipboard, furnishings as well as sawdust mills.



With more companies engaging in biomass fuel manufacturing, the competitors on the raw products come to be a lot more strong. As the crop straws in Sweden are in scattered circulation, they are difficult to accumulate and also process. So some manufacturers and also institutes are establishing new materials like peat and power crops.



Wood pellet producing technology and tools

The pellet molding modern technology has developed in Sweden. Nowadays, it has attained commercial and also market manufacturing. The manufacturing process features high automation, needing less operators. The picture listed below showed the wood pellet manufacturing procedure.



Drying: typically, the dampness content of sawdust is around 50%. A drum clothes dryer can lower the dampness web content to 9-12% to ensure that it is gotten approved for making pellets.

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

Conditioning: include high-heat steam to the raw products and soften the cellulous in it. Over half of the pellet fuel producers have conditioning process in production.

Pellet molding: most wood pellet manufacturing facilities utilize upright kind ring die pellet maker. The production capacity of one maker is 2-4ton/ h. The life span of ring die is 2000-3000h, while the roller can last 1000-1500h.

Cooling: the wood pellets extruded out from the pellet maker go to the temperature level of 100 ℃. Pellets under this problem are simple to damage as well as troublesome for transport. A counter-flow colder can cool the wood pellets in a moderate means.

Packaging: the cooled down pellets need to be identified and packaged according to consumers' need. Little bags are 16kg, big bags are 900kg. For big consumers like power plant, the wood pellets are transported by vehicles and ships in bulks.

Biomass pellets category as well as application

In 1999, Sweden federal government published the requirement of wood pellet fuel, in which they are identified right into 3 classes. The extraordinary has excellent quality. They can be made use of in residential tiny burners and stoves.The 2nd as well as 3rd don't have top quality. They are made use of by large industrial customers.



Presently, 57% of the wood pellet fuels in Sweden can satisfy this requirement. Several of them can satisfy the EU requirement, others are not generated according to this criterion.



Wood pellet fuel can be applied in small central heating boilers, medium-scale as well as large-scale heating supply center and also nuclear power plant. Presently, Sweden has 60% of wood pellet fuel for tiny as well as medium home heating central heating boilers and also local home heating supply facility, and also 40% for big heating supply center and co-firing nuclear power plant.



From the 1970s to the 1990s, Sweden regional heating plant take on coal to replace oil. After the pass of CO2 exhaust tax, these heating plant resort to biomass fuel from coal. In https://carmenrichi.car.blog/2022/08/08/gemstones/ , the amount of biomass fuel for heating expands from 1.1 PJ to 57PJ. Presently, about 400 regional heating plant has actually taken on wood pellet fuel.



Since the mid 1990s, residential wood pellet market has actually made terrific development. In the last years, using domestic home heating wood pellets grows rapidly. Presently, Sweden has 200,000 households making use of wood pellet central heating boilers, 40,000 families using wood pellet ranges.



Sweden biomass energy growth objective and policy

To advertise the continuous advancement of biomass power, Sweden has actually made a series of laws and also plans. To make sure the execute of these policies, the federal government additionally made many feasible guidance steps and also necessary industry requirement.



Sweden not just fulfill the obligation stipulated Kyoto Protocol that reduced greenhouse emission by 8%, but likewise set its own development goal of biomass power. In 2006, the Priest for lasting advancement department asserted that Sweden will completely make use of biofuels and also stop making use of oil, and also become the initial country that totally rely on renewable energy.



By 2020, Sweden will enhance its percentage of renewable energy to 50%, the usage proportion of renewable energy in transport sector to 10%, power efficiency by 20%, as well as reduced the discharge of greenhouse gas by 40%.



Wood pellet fuel reward plan

Sweden has carried out high cost acquisition, investment aids, tax decrease as well as exemption, quota system and other biomass power incentive plan.



Given that 1975, Sweden invests 36 million Euro from federal government budget to sustain biomass technology advancement. From 1997 to 2002, the federal government provided 25% investment aid to biomass cogeneration projects. From 2004-2006, the federal government provided 1350 Euros for citizens who use biomass heater.



Sweden usually lay high tax obligation on fuels, powers, CO2, SO2, and so on. To advertise the growth of biomass power, to exempt all taxes on biomass projects. In 1991, Sweden government begins to lay tax obligation on carbon dioxide exhaust, that makes the price of oil and also nonrenewable fuel source increase. Many heat supply facility as well as nuclear power plant switches from nonrenewable fuel source to biomass fuel.



To motivate the power plant to make use of biomass energy, Sweden federal government introduced electrical power quota system. This policy requires the power vendors to have particular portion of electrical energy generated by renewable resource. For each 1MWh electricity, the federal government will provide tax relief based on the biomass power quantity.
