Sawdust Charcoal Briquettes as Alternative Fuels For Small and Medium Industry


The high energy need and on the other side fossil fuels is expensive too with occasional scarce encourage the use of alternative fuels from biomass. Biomass waste that pollute the environment initially is basically a potential feedstock for renewable energy, environmentally friendly, cost-effective and does not damage  the flavor of food, if used especially in the food industry. In terms of fuel because derive from biomass it is considered as carbon neutral.
Charcoal briquettes from hardwood sawdust which has a calorific value above 7000 kcal/kg and high hardness is superior charcoal for various purposes. Here are some applications that can utilize hardwood sawdust charcoal briquette. 



1.      Aluminum Metal Casting Industry
Metallic aluminum (Al) has a melting point of only about 700 C or lower than other types of metals such as iron, steel and so on, thus requiring specification fuel with a lower calorific value than iron and steel foundry. Charcoal briquettes from hardwood sawdust can be as fuel for the aluminum foundry.


2.      Poultry Industry
The new chickens are hatched until the age of 2 weeks (DOC = days old chicken) require continuous heating with controlled temperature. LPG prices are more expensive to encourage more farmers to switch to using this alternative fuel. Charcoal briquettes with a long flame time and temperature can be controlled, it becomes an attractive alternative. Control is done with blower equipped instrument air regulator valve so that the heat input included in the chicken coop can be controlled.


3.      Restaurants and Catering
Cooking in large quantities with longer duration are characteristic of the restaurant and catering business. This charcoal is perfect for cooking such a pattern. Households generally cook a little amount and short duration is not very suitable for the use of charcoal briquettes. High heat, longer time of the flame and not damage the taste of food is a major advantage factors of this charcoal briquettes.


4.      Sate of Goat & Sate of  Cow
The use of charcoal briquettes that do not damage the flavor of food, will be thoroughly tested on sate of goat. This is due to the direct contact between fuel briquettes with sate of goat. Precisely because of this briquette generates high enough heat the sate position should be made a bit away from charcoal when burned so as not to overcook (charred). While the sate of chicken because very quickly matured, it will quickly charred, so it does not fit.
 

5.      Angkringan Shop
Shops that are synonymous with "three kettles" cafĂ©  (water, ginger and tea) is very flourishing in various areas, especially Java island. Various other menu such as fried foods, small rices and snacks are also commonly served at this shops. Water to make hot drinks should be keep hot so that it need the heat source is durable and light up continuously. With the use of charcoal briquettes is more efficient than ordinary wood charcoal but only requires special stove equipped with refractory cement. Experience showed with common stove (Java language: anglo,from clay) will rupture with the charcoal briquettes because of the heat.

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…
