Compressed rice husk biomass fuel

Compressed rice husk biomass fuel for boiler

Using rice husk as fuel for boilers will solve many issues that existed in the past at rice milling factories where a large amount of rice husk was discarded or burnt, causing significant environmental pollution. Moreover, using rice husk as a natural fuel for cooking, brick-making, and boiler fuel is very cost-effective compared to other fuel sources. However, the problem lies in the transportation and storage process, which requires a lot of labor and space.

Currently, in Vietnam, manufacturers have produced a compression machine that compresses rice husks into small pellets with a size of a few millimeters. This process is convenient for transportation, storage, and the burning capacity of the compressed pellets.

Compressed rice husk pellets are an environmentally friendly biofuel. When burnt, they emit less ash and smoke than other fuels such as coal. Furthermore, the compressed pellets are produced from waste by-products from rice milling factories. This means that using this material as a fuel source can reduce waste management issues.

The small size of the compressed pellets is convenient for use in machinery, with high combustion efficiency, especially for boilers and other applications. The compressed pellets have a low moisture content (less than 10%) and a low ash content (1.17%). They also have a high calorific value of 4260 kcal/kg.

Characteristics of compressed rice husk pellets:

• Diameter: 6-8mm
• Length: 10mm
• Moisture content: <8%
• Ash content: 1.17%
• Calorific value: 4260 kcal/kg.
