Sweden biomass pellet fuel industry analysis<br>
chicken feed manufacturing machine is just one of the world's largest wood pellet fuel producer as well as consumer. It's wood pellet production modern technology, industry policy, as well as market version are prominent. In this passage, I will do comprehensive evaluation on Sweden biomass pellet fuel market, as well as work out some valuable experiences.



Introduction

In the 1970s, lots of countries have made policies to advertise biomass power as a way to cope with energy crisis and also setting pollution. Since then, biomass power industry has created quickly, as well as the modern technology maintain improving.



Because of the lack of mineral sources, Sweden's economic climate endured wonderful loss in last century. To make certain nationwide power safety, Sweden federal government strive to create renewable energy.



Biomass pellet fuel has the attributes of high burning performance, low ash material, absolutely no carbon exhaust, simple transport, which has been popular in Europe and The United States And Canada. With abundant forestry sources, Sweden pay much focus to the growth of biomass pellet fuel. Sweden uses up 20% of the world's biomass fuel consumption, which matures at the speed of 8-10%.



Sweden forestry resources as well as biomass products

Sweden has abundant forestry sources. The forest covers 64% of the acreage, with 51% had by individuals, 24% by huge wood companies, and also 25% by countries and also other public organizations. Besides, the forestry expands by 100 million lots each year, as well as the deforestation quantity is 92.4 million heaps. The significant forestry sectors are wood processing, paper handling, as well as power wood. The wood products for making biomass power primarily come from the 3 industries above, concerning 23.48 m3.



Resources of wood pellets

Of the raw materials for making wood pellets, wood shavings take up 53%, sawdust 35%, and also wood chips 5%, others (barks, agriculture residues, energy forestry) uses up 7%. Some little wood pellet manufacturing facility are developed base upon chipboard, furnishings as well as sawdust mills.



With even more firms participating in biomass fuel production, the competitors on the raw products become extra strong. As the crop straws in Sweden are in scattered circulation, they are hard to gather and process. So some producers and institutes are establishing brand-new products like peat and also energy crops.



Wood pellet manufacturing modern technology and equipment

The pellet molding innovation has developed in Sweden. Nowadays, it has accomplished commercial as well as market production. The production process includes high automation, needing much less operators. The picture listed below displayed the wood pellet manufacturing process.



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

Crushing: the size of resources should be under 5mm. They require a hammer mill to minimize the size.

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

Pellet molding: a lot of wood pellet factories make use of vertical type ring pass away pellet equipment. The manufacturing capability of one maker is 2-4ton/ h. The service life of ring die is 2000-3000h, while the roller can last 1000-1500h.

Cooling: the wood pellets extruded out from the pellet machine are at the temperature level of 100 ℃. Pellets under this problem are very easy to break and also inconvenient for transportation. A counter-flow cooler can cool down the wood pellets in a moderate method.

Packaging: the cooled down pellets require to be classified and packaged according to customers' demand. Little bags are 16kg, big bags are 900kg. For huge clients like nuclear power plant, the wood pellets are moved by trucks and also ships in bulks.

Biomass pellets classification and application

In 1999, Sweden federal government released the standard of wood pellet fuel, in which they are identified right into 3 classes. The fabulous has excellent quality. They can be utilized in domestic tiny heaters and stoves.The 2nd and 3rd don't have excellent quality. They are used by big commercial clients.



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



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



From the 1970s to the 1990s, Sweden local heating plant take on coal to replace oil. After the enact of CO2 emission tax, these heating plant turn to biomass fuel from coal. In the last decade, the quantity of biomass fuel for heating grows from 1.1 PJ to 57PJ. Presently, concerning 400 regional heating plant has actually taken on wood pellet fuel.



Considering that the mid 1990s, domestic wood pellet sector has actually made fantastic progress. In the last decades, making use of residential heating wood pellets proliferates. Currently, Sweden has 200,000 families making use of wood pellet central heating boilers, 40,000 families using wood pellet ranges.



Sweden biomass power advancement goal and also plan

To promote the continuous growth of biomass energy, Sweden has actually made a collection of regulations as well as plans. To make certain the carry out of these policies, the federal government likewise made lots of feasible supervision measures as well as obligatory industry standard.



Sweden not just meet the commitment stipulated Kyoto Protocol that reduced greenhouse discharge by 8%, yet also established its own development goal of biomass power. In 2006, the Priest for lasting advancement department asserted that Sweden will entirely use biofuels and quit using oil, and end up being the first country that totally depend on renewable energy.



By 2020, Sweden will certainly increase its proportion of renewable resource to 50%, the usage proportion of renewable energy in transportation market to 10%, power effectiveness by 20%, as well as reduced the discharge of greenhouse gas by 40%.



Wood pellet fuel incentive policy

Sweden has actually executed high cost procurement, financial investment subsidies, tax reduction as well as exemption, quota system and various other biomass energy incentive plan.



Because 1975, Sweden invests 36 million Euro from federal government budget to sustain biomass technology growth. From 1997 to 2002, the government provided 25% investment subsidy to biomass cogeneration jobs. From 2004-2006, the federal government provided 1350 Euros for locals who utilize biomass heater.




Sweden usually lay high tax obligation on fuels, powers, CO2, SO2, etc. To advertise the advancement of biomass energy, to excuse all taxes on biomass projects. In 1991, Sweden government starts to lay tax obligation on CO2 discharge, that makes the price of oil as well as nonrenewable fuel source increase. A lot of heat supply facility and power plants changes from fossil fuel to biomass fuel.



To encourage the power plant to use biomass energy, Sweden federal government introduced electric power quota system. This policy calls for the power providers to have particular section of power generated by renewable energy. For every single 1MWh electricity, the federal government will certainly provide tax obligation relief based on the biomass power amount.



Sweden wood pellet fuel melting device

Sweden wood pellet shedding innovation remains in the leading placement. There have actually mored than 20 pellet burner producers, over 50 sorts of wood pellet central heating boilers, 120,000 sets of pellet central heating boilers, 20,000 collections of pellet ranges. As there are still several households using electrical heating, the pellet central heating boilers have substantial possibility.



Sweden pellet burning devices has main home heating central heating boiler and also biomass stove 2 types.




Central home heating boiler can be utilized in 1 or even more households. The thermal send with water. The powers are 10-40kw, which can be readjusted by 30% -100% according to demands. The central heating boilers likewise has 2 types. The combined central heating boiler is connected by a pellet heater and a common boiler. The boiler can get in touch with various burners. The incorporated boilers are mainly imported from Austria and also Germany, some created by domestic producers.



Biomass ranges or heating system

Biomass cooktops additionally has 2 types. Independent pellet oven as well as Chimney item type heating system. The former on is more popular. The independent pellet cooktop has a pellet stock bin within, which can hold wood pellets for 2-day use.



Biomass pellet oven can realize automated dental filling and also burning. Based on various feeding approach, pellet ovens has top feed, lower feed as well as straight feed 3 types. Leading feed pellet stoves are one of the most preferred. Owing to high benefit and tidiness, small pellet cooktops sell well in recent times.
