How Moisture Affects The Biomass Briquetting Process

The biomass briquetting machine compresses a large amount of biomass raw materials into different shapes by heating and pressing techniques and this process is known as the biomass briquetting process. The irregular shape, size, and high moisture of biomass waste make it hard to transport, utilize, store, and process. Besides, there are multiple other factors that affect the procedure of biomass briquetting machines. One of the main factors is raw material moisture that affects the briquetting process. So, in this blog, we will discuss how moisture affects the biomass briquetting process:

 

Raw biowaste with low moisture:

The particles are not sufficiently extended, and the surrounding particles are not tightly bound and cannot be formed when the moisture content of the biomass material is too low. For instance, the trace moisture is vaporized at a high temperature if the moisture is too low. A recent study shows that during briquetting, biomass such as reeds and corn stalks are suitable with moisture around 12% to 18%. The density of the biofuel briquette is maximized and leftovers relatively stable over a suitable moisture range. The density of the briquette fuel starts to reduce when the moisture is increased to a certain amount. The lower moisture raw material is produced the biofuel briquette whose have the tendency to absorb moisture in the air, the reason behind it is that the biofuel briquette to deform and burst, as well as diminishing the briquette density. 

 

Raw biowaste with high moisture:

The particles can be sufficiently extended in the direction perpendicular to the maximum stress if the moisture of the raw material is too high. However, the particles can be engaged with each other because more water in the raw material is ejected and it is divided among the particles layers so that the particles are separated. Moreover, the distance among the molecules is increased, by too much water vapor and it affects heat conduction and lowers the briquetting temperature. Consequently, decrease in the bonding force. So, the heating temperature needed in the briquetting procedure is increased when the moisture content of the raw material is too high. The forming briquette is experienced in that the excessive moisture increases the radical force, which also boosts the power consumption.

 

Simultaneously, a component of the heat of the preheating matter of the biomass briquetting machine is used on the surplus water, the evaporated water is rapidly vaporized but the steam can’t be released from the molding the cylinder in time, consequently in volume expansion, simply forming a gas blockage, forming steam pressure in the longitudinal direction of the cylinder, and occupying a boost in space. The biofuel will be cracked and the surface is rough when the steam pressure is minor. The disintegration may affect the subsequent transportation and packaging because of the high-pressure water vapor inside the biofuel briquette after the biofuel briquette is ejected from the forming sleeve.

 

Final words

The effect of biofuel briquette is the consequence of a combination of a lot of factors, but moisture plays a crucial role in the formation.
