Description

목재 펠릿 생산 시스템{Production system for wood pellet}Production system for wood pellet}

본 발명은 목재 펠릿 생산 시스템에 관한 것으로서, 특히 목재 펠릿을 형성하는 원료인 나무의 종류에 상관없이 우수한 품질의 목재 펠릿을 생산할 수 있는 목재 펠릿 생산 시스템에 관한 것이다.The present invention relates to a wood pellet production system, and more particularly, to a wood pellet production system capable of producing wood pellets of excellent quality regardless of the type of wood used as a raw material for forming the wood pellets.

목재 펠릿(Wood pellet)은, 바이오에너지의 생산이 가능한 목질계 바이오매스의 고체 연료 중 하나로, 낮은 비용으로 고품질의 에너지를 생산할 수 있는 신재생에너지원에 해당한다. 통상 목재 펠릿은 산림에서 생산된 목재나 이를 가공하는 과정에서 발생한 잔재를 톱밥, 대팻밥 등으로 잘게 파쇄하고 건조한 후 압축하여 지름 6~25mm, 길이 32mm 이하의 크기를 가지는 작은 원통형 제품으로 생산된다. Wood pellets are one of the solid fuels of wood-based biomass capable of producing bioenergy, and correspond to a new renewable energy source capable of producing high-quality energy at low cost. In general, wood pellets are produced by crushing wood produced in forests or residues generated in the process of processing them with sawdust or shavings, drying them, and then compressing them into small cylindrical products having a diameter of 6 to 25 mm and a length of 32 mm or less.

이러한 목재 펠릿은, 원목에 비해 3배 이상 운송, 보관 등이 가능하며, 에너지 밀도가 높아 목재 펠릿 1톤으로 원유 약 500L를 대체할 수 있고, 가격이 경유의 약 70% 정도 수준으로 다른 연료에 비해 경제적이다.These wood pellets can be transported and stored three times more than raw wood, and have high energy density, so 1 ton of wood pellets can replace about 500L of crude oil, and the price is about 70% of that of diesel, compared to other fuels. more economical than

또한, 일정한 규격으로 생산되므로 안정적으로 원하는 만큼의 에너지를 공급할 수 있으며, 수분 함량이 15% 이하로 적어 장기간 보관할 수 있다. 그리고 목재 펠릿을 이용하여 에너지를 생산할 경우, 이산화탄소와 같은 온실 가스나 황산화물, 질소산화물 등의 대기 오염물질의 배출이 적어 친환경적이다.In addition, since it is produced in a certain standard, it is possible to stably supply as much energy as desired, and it can be stored for a long time as the moisture content is less than 15%. In addition, when energy is produced using wood pellets, emissions of greenhouse gases such as carbon dioxide or air pollutants such as sulfur oxides and nitrogen oxides are low, which is environmentally friendly.

이처럼 이점으로 인해, 목재 펠릿 산업은 계속적으로 성장하고 있다. 그러나, 현재 목재 펠릿을 생산하는 시스템은, 원료가 되는 나무의 종류에 상관없이 히팅 설비, 건조설비를 하나만 구비하고 있는바, 수분 함량이 10% 이하인 우수한 품질의 목재 펠릿을 생산하기 어렵다는 문제가 있다. Because of these advantages, the wood pellet industry continues to grow. However, the current system for producing wood pellets has a problem in that it is difficult to produce wood pellets of excellent quality with a moisture content of 10% or less, since it has only one heating facility and one drying facility regardless of the type of wood used as the raw material. .
