The villages use a large amount of biomass as fuel and to convert biomass into fuel it has to be made into briquettes through the briquetting process. In order to convert raw materials into briquettes, it is important that raw materials are compressed under high pressure and then if needed a binder is added to ensure proper functioning of briquetting machine.
Biomass briquetting has increased in the recent past due to its efficiency and for possessing high calorific value. This particular process also helps in creating briquettes that are smokeless thereby making them more hygienic for the rural areas.
Different Techniques
Everyone is aware that in today’s day and age the supply of fossil fuel is not able to keep up with the pace of the every day increasing demand for energy. Therefore it is time to think of an alternate source of energy and briquetting is one of the best options available today. There are two main techniques for converting agro waste into Briquetting Fuel and they are:
Pyrolysed Briquetted Fuel
This process includes turning waste into charcoal at extremely high temperature of around 275-300°C in the absence of oxygen and through this process briquetting is done. Pyrolysis means dry distillation where the organic matter is heated in the absence of air at 400°C and this ends up releasing an array of energy rich products that can be gaseous as well as liquid. The oils that are formed through pyrolysis are usually combination of hydrocarbons, aldehydes, ketones and other organic compounds. The gases are a combination of carbon dioxide hydrogen, carbon monoxide, methane, ethylene, ethane and other hydrocarbons.

Direct compaction briquette fuel
In this type of briquette fuel generation, no binding medium is used to compress the waste or biomass. There are two steps to this process where high pressure is used to semi fluidizing biomass under which condition the residue gets heated to about 182°C, and then the lining flows and therefore acts as a binder.
The second process is of extracting the material in room temperature. In this kind of scenario there doesn’t exist the requirement to add external agent such as binder or glue. The existing units are imported through the usage of briquetting machine that are of 400 kg/cm2 capacity. These two are the basic processes for creation of briquette fuel.
