Sectors of Pellet Fuel Usage

As a source of energy or wood pellet fuel or pellet fuel can be used in small-scale such as the household to large-scale on power plants. Both quantity and quality pellet are the parameters in its use in relation to equipment that is used. Basically from small-scale to large scale on the use pellet fuel especially related to efficiency factor, easy in operation, safety and gas emission impact (eventhough wood pellet include as renewable fuel that enter the category as carbon neutral) while the use on large-scale the qualityfactor of pellet got a serious attention. Technology that was used to utilize the wood pellet is almost all use combustion technology (direct combustion) to get output in form of heat or electricity.

In small-scale the use pellet fuel for mainly in the four season countries for room/space heating, even for this sector needs premium quality of wood pellet for pellet stove. Pellet stove has not yet been familiar in Indonesia because the wood pellet also still very difficult to get. Other equipment that are to be used in small-scale is boiler and burner. Boiler system will produce steam to source of steam and hot water. While burner can be used for various source of heat.

On the medium-large scale, users mainly for industries and coal-fired power plants. Grate combustor and stoker are equipments that general used in the industry. Pulverized technology system and fluidized bed commonly used in power plant. The percentage of wood pellets this time is still less than 5 percent on the use of cofiring in the coal powerplant. Wood pellet for pulverized while biomass pellet for fluidized bed. The characteristics of both pellet cause of the difference.

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 …
