甚麼是木質顆粒? What are wood pellets?
完整炭循環 - Complete Carbon Cycle Mechanism
木質顆粒的外型
木質顆粒係乾燥木材粉碎並經擠壓台成型者。
顆粒外觀及燃燒狀態如左圖所示，直徑6～8mm，長度5～40mm的圓棒狀，主要用於暖爐及鍋爐的燃料。
Appearance of wood pellets
Wood pellets are dried wood that is crushed and shaped by extrusion.
The appearance and combustion state of the pellets are shown in the left figure. They are round rods with a diameter of 6-8mm and a length of 5-40mm. They are mainly used as fuel for furnaces and boilers.
零炭排
由於木質顆粒原料來樹木，而樹木在生長過程之光合作用時吸收空氣中的二氧化碳並固定在木材中(木材中碳元素占50%)。當木質顆粒燃燒時產生之二氧化碳，只是將在樹木在生長期間所吸收的二氧化碳排放到大氣，並未造成增加大氣的ニ氧化碳之濃度的情況，因此木質顆粒燃料爲碳中性之環保燃料。
Zero carbon emission
Because the raw material of wood pellets comes from trees, and the trees absorb carbon dioxide in the air during photosynthesis during the growth process and fix it in wood (the carbon element in wood accounts for 50%). The carbon dioxide produced when the wood pellets are burned only emits the carbon dioxide absorbed by the trees during their growth into the atmosphere, and does not cause an increase in the concentration of carbon dioxide in the atmosphere. Therefore, the wood pellet fuel is a carbon-neutral environmentally friendly fuel.
燃燒穩定快速
一般農作物秸稈、木屑都具有疏鬆、密度小、單位體積的熱值低等缺點，作為燃料使用很不方便，生物質成型燃料成型技術不僅能有效地解決這一問題，而且能有效地改變木屑、秸稈等的燃燒特性，實現快速、潔淨燃燒。生物質成型燃料成型技術即是通過粉碎、乾燥、機械加壓等過程，將鬆散、細碎的桔杆、農業廢棄物壓成結構緊密顆粒狀燃料，其能量密度較加工前要大十倍左右，這種生物質成型燃料便於貯運，燃燒後排放的煙灰和SO2遠低於重油，是一種適合於工業鍋爐使用的高品位燃料。生物質成型燃料燃料可以看作一種綠色煤炭，是一種新型潔淨能源。
Stable and fast combustion
Generally, crop straw and wood chips have the disadvantages of looseness, low density, and low calorific value per unit volume. Combustion characteristics of straw, etc., to achieve fast and clean combustion.
Biomass briquette fuel briquette technology is to compress loose and finely divided orange stalks and agricultural waste into compact granular fuel through crushing, drying, mechanical pressing and other processes, and its energy density is about ten times higher than that before processing. This biomass briquette fuel is convenient for storage and transportation, and the soot and SO2 emitted after combustion are far lower than that of heavy oil. It is a high-grade fuel suitable for industrial boilers.
Biomass briquette fuel can be regarded as a kind of green coal, which is a new type of clean energy.
為何選木質顆粒? Why Choose Wood Pellets?
無可取代的優點 - irreplaceable advantages
運輸危險性小
運輸石油的油輪若油管破裂或漏油，會造成海洋或是地下水源的環境汙染，亦可能爆炸造成傷亡。而運輸木質顆粒則不太容易有類似意外發生。而且木質顆粒較好儲存與運輸長距離，也方便依照客戶的需求放置於儲料箱。
Less dangerous to transport
If the tanker transporting oil breaks or leaks oil, it will cause environmental pollution of the ocean or groundwater sources, and may also explode causing casualties. The transportation of wood pellets is less prone to similar accidents. Moreover, wood pellets are better stored and transported over long distances, and it is also convenient to place them in storage boxes according to customer needs.
供應源及價格穩定
因木料具可回收性，一般來源皆取自產地，隨著市場的穩定持續發展，木質顆粒的來源穩定性高。而歐美國家每年的暖氣費用計算，對每個家庭都是一項必須斟酌計算的經濟課題，相對於油價的不穩定，因此許多消費者較願意購買木質顆粒。
Supply and price stability
Because wood is recyclable, it is generally sourced from the place of origin. With the stable and continuous development of the market, the source of wood pellets is highly stable. The annual heating cost calculation in European and American countries is an economic issue that must be carefully calculated for every family. Compared with the instability of oil prices, many consumers are more willing to buy wood pellets.
溫室氣體減量
木質顆粒與其他傳統能源(石油、天然氣、煤)比較起來，更具環保概念。若一個家庭單位能將暖氣油料轉變成用木質顆粒，則每年約可降低5公噸的二氧化碳排放。
Greenhouse gas reduction
Compared with other traditional energy sources (oil, natural gas, coal), wood pellets are more environmentally friendly. If a family unit can convert heating oil into wood pellets, it can reduce carbon dioxide emissions by about 5 metric tons per year.
降低空氣汙染
懸浮微粒(Particulate Matter, PM)2.5是指直徑小於2.5微米的粒子，可直進被人體呼吸系統進入肺部，直借或間接影響呼吸器官，造成吸呼道過敏、皮膚過敏…等。
燃燒生煤及石油焦是PM2.5主要來源之一，若禁用生煤及石油焦後，估計每年可減少硫氧化物5595公噸（40%）、粒狀物757噸（73%）、氮氧化物8200噸（53%）等汙染源，對空氣品質改善有極大助益。
Reduce Air Pollution
PM2.5 refers to particles with a diameter of less than 2.5 microns, which can directly enter the lungs of the human respiratory system, directly or indirectly affect the respiratory organs, and cause respiratory allergies, skin allergies, etc.
Burning raw coal and petroleum coke is one of the main sources of PM2.5. If raw coal and petroleum coke are banned, it is estimated that 5,595 tons (40%) of sulfur oxides, 757 tons (73%) of particulate matter, and nitrogen oxides can be reduced each year. 8,200 tons (53%) and other pollution sources, which are of great help to the improvement of air quality.
再生能源法令
歐陸國家自海外進口木質顆粒，有一半以上皆使用於發電廠。歐盟再生能源法另強勢主導再生能源的發展和使用，並規定歐盟會員國在2020年須達到再生能源佔全國能源使用的20%。2015年12月的巴黎氣候高峰會，聚集了來自200個以上的世界國家領袖，共同協議降低全球的碳排放量，希望可降低地球暖化的速度，並鼓勵各地方政府應致力於使用再生能源。
Renewable Energy Regulations
Continental countries import wood pellets from overseas, more than half of which are used in power plants. The EU Renewable Energy Law also strongly guides the development and use of renewable energy, and stipulates that EU member states must achieve renewable energy accounting for 20% of national energy use by 2020. At the Paris Climate Summit in December 2015, leaders from more than 200 countries gathered to jointly reduce global carbon emissions, hoping to reduce the speed of global warming, and encouraging local governments to commit to using renewable energy .
