At present, biomass briquette grows rapidly in the market. Numerous factors will influence the biomass briquette creating process. However, in the briquette machine manufacturing company the Biomass briquette machine manufacturer does many efforts to improve the biomass briquette quality process in the briquette machine. But you can do extra effort to get better the biomass briquette quality. Generally, they are divided into the internal type (moisture, raw material, etc) and external type (pressure, the size of raw material, heating temperature):
The heating temperature
Heating temperature is a huge influence on the briquette strength and density. For the same raw material, the needed briquetting pressure will be lower in high temperatures with certain moisture. As you all know, biomass briquette is usually a binder-free way since you use the binder lignin. When the temperature around 70 to100 Celsius then the lignin will become soft. When the temperature rises then the binding affection will become better. Lignin will be melted when the temperature comes to 160 Celsius and makes a type of gel that creates the binding effect much strong.
The briquette and pressure maintaining time
When it’s small while it affects little then the pressure will highly affect the briquette quality. The pressure-keeping time can be ignored in super high pressure. Normally, the quality of affection can be ignored if the pressure-keeping time is more than 40 seconds. And an extra 10 seconds on pressure keeping will grow the briquette density by 5% when the briquette creating time is more than 20 seconds.
The briquette speed and mold size
With the shapes and size, the briquette pressure has much to do. Studies show that briquettes with smaller sizes with being bigger in density with the same pressure and material. Length and diameter rate amid 8 to 10 is a good size to get high-quality biomass briquette.
Raw material type
When briquette at normal temperature then the wood waste is with low plasticity. Whereas biomass with a high fiber rate is easy to briquette. Briquette with heating system, raw biomass with high lignin such as straw, wood type, etc is good. As on the high temperature, the lignin creates a better performance that highly boosts the plasticity.
Wetness of the raw material
Wetness will affect the density burning effect and relaxation of the biomass briquette. Proper moisture will help to pass pressure on a well lubricating and the particles. Usually, for diverse biomass material, the briquette moisture should be around 15%. So, we need to do to make a high-quality biomass briquette to make the raw biomass well dried. First, part of the briquette energy will cost on the extra when briquette with high moisture. Second, the heating formulates some of the extra moisture to be steam, which causes “steam pressure” on briquette creation. The light steam pressure will create the briquette crackle; the hard steam pressure will even create a steam bomb, which will reason a risk to the briquette-making procedure.
Compressed size of the raw material
The compressed sizes will influence the quality metrics of the briquette-water resistance, relaxation, fall resistance, and density. The size of the raw material should be smaller than the mold briquette output whole size when the raw material is briquette by a certain kind of briquette machine. It will increase power consumption and reduce the efficiency of the briquette machine if the raw material is all in big sizes.
Conclusion
Biomass briquette making now becomes well-liked as the progress of renewable energy. So, these are the main factors to get better the biomass briquette quality.
