Torrefied Wood: Biomass Fuel of Substituting Coal in The Future

Compared to conventional biomass fuels such as wood pellets are only capable of a maximum of 10% in co-firing with coal because of the nature of chemistry and physic  are much different whereas if the percentage of co-firing with coal increased to 20% required the addition of a large investment for the handling and processingnya, then torrefied wood even capable of co-firing with coal to 40%. Another advantage is on the side of the powerplant also just needed a little extra investment for handling and processingnya for torrefied wood, due to the physico-chemical properties are not much different.

Densification or compaction into pellets or torrefied wood briquettes will also give a more significant savings than wood pellets, ie 15.0-18.7 MJ/m3 on torrified pellets and  7.5-10.4 MJ/m3 at wood pellets. Because the torrefied wood brittle, so it can be burned with coal dipulverize and more advisable, instead of using the material handling, processing to a separate injection system. This will result in significant savings on equipment modification when cofiring at a greater percentage. A number of agro-industry waste biomass such as empty fruit bunches and palm thatch can torrefaksi as well as woody biomass, to enhance combustion conditions in the coal system.
Torrefied wood cofiring has been successfully carried out one of them in the coal power plant in Borselle, Netherlands. Research also shows that the smoothing torrefied wood into powder with a specific particle size distribution and allows for the smooth fluidization regimes on the feeding entrained flow process (gasifier and pulverized coal boilers).

Carbon Positive, Carbon Carbon Neutral or Negative?

Greenhouse gases from burning fossilfuels have caused the Earth's temperature to rise. Increasing the temperature of the earth or global warming causing numerous disasters due to climate change in a number of places on earth. When greenhouse gases not controlled then the result of damage to the environment of the earth will be more severe. Therefore, efforts were made to reduce greenhouse gases as the cause of environmental problems. In general, there are four common scenarios to prevent the global warming effect of CO2 in the atmosphere gradually, namely: 1.increasing the efficiency so the fossil fuel consumption decreases, 2.mix of renewable fuels with fossil fuels so that fossil fuel consumption has also decreased, 3.substitution of fossil fuels with renewable fuels 4.and the absorption of CO2 in the atmosphere so that the concentration of greenhouse gases can be reduced. Here are some basic terms related to the above problems. Based on the origin and the effect that CO2 in the atmo…

10 Advantages By Making Energy Plantations for Wood Pellet Production

Assuredness of supply of raw materials is one of the key factors of business success in the wood pellets. There are two ways to obtain raw materials commonly done today: a. Buying from the owner of source of raw materials. b. Producing its own the availability of raw materials. While the 3rd way and there is still few for business owners make wood pellets is by mix way, which is partly provide by their own of raw materials and some rest buy from the other source of raw materials.
While examining at the types of biomass raw materials there are two kinds, namely : a. Woody biomass b. Non-wood biomass such as agricultural wastes (empty fruit bunches of palm oil trees, corn cobs, rice husks and so on). Currently woody biomass remains a priority to be products of wood pellets as a number of advantages over non-wood biomass which is generally an agricultural wastes, are included in the category of biomass pellets or agri-waste pellets. The comparison between wood pellet and biomass pellet …
