Biomass Densification For Pellet And Briquette



Biomass in general has a large volume so it is not efficient in transporting and handling. So as to resolve the issue needs to be compressed in volume of biomass by means of a press machine. Application of pressure especially with the high temperatures make the biomass will be compressed and strong glue. The compression will make solid fuel which has a higher energy density per volume is the same. In general, this way no longer needed extra adhesive from the outside, because lignin compounds in the biomass that will act as a binder.

Pellet is currently produced by large-scale and large users while briquettes are generally produced on a smaller scale and its not as much as pellets. Both pellets and briquettes made ​​from hardwood and softwood. At a glance we can distinguish pellets and briquettes based on its dimensions. Smaller sized pellets with a diameter of about 10 mm while the larger sized briquettes with a size of about 50 to 100 mm with a length of typically 60 to 150 mm and even larger. Biomass fuels has gained the attention and interest as environmentally friendly (almost zero sulfur content) and including renewableenergy. Application of biomass pellets and briquettes for household fuel to industries.
Energy content is the critical point for a number of users. For example, the high calorific value could create higher combustion temperatures and potentially damage the furnace. Used pellet and briquette exports need to be sampled and tested to ensure the applicable standards. Wood briquettes or Synthetic Logs or Uncarbonized Briquette is different from charcoal briquettes, because the raw material of wood briquette is biomass (usually sawdust) that are not charred / carbonized or physically resembles wood pellets only bigger.

As a carbon neutral fuel because it comes from biomass, pellets and briquettes are alternative heating fuel to coal heating and boiler which could be used for a variety of modern combustion systems. As fuel both briquettes and pellets is comparable with coal in terms of energy content, and offers a variety of gas emission reductions of NOx and SOx and low ash content. In a number of countries in Europe and America, pellet and briquette fuels is becoming more popular these days because of the urge to use  renewable and environmentally friendly fuel.

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 …

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…
