Biomass briquette is a type of
renewable briquette which is much in demand in recent years and, there are many
factors that can affect the biomass briquette quality. By using the useful tips
given in this article, you will be able to improve biomass briquette quality.
Numerous factors will influence the biomass briquette. There are divided into
two parts. The first part is –internal part and the second part is the external
part. Its internal part mainly contains raw material. While the external part
includes the heating temperature, pressure, and the size of the raw material.
If you want to know about tips on biomass briquette quality and the working
process of Briquette Machine,
this article is for you.
The
heating temperature
The
heating temperature has a great impact on the briquette density and strength.
For the same raw materials with certain moisture, the necessary briquetting
pressure will be lower in high temperatures. As you know, biomass briquette is
typically a binder-free wat as we are the internal binder lignin. Around
temperature 70 to 100 degrees Celsius, the lignin will become soft. When the
temperature will rise, the binding affection will become better. The lignin
starts melting when the temperature is reached at 160 degrees Celsius. And it
turns into a gel that makes the binding effect much strong
The
briquette pressure
In the
biomass briquette making process, pressure is regarded as the most important
factor. This briquette process is divided into three steps. The first step is
soft briquetting-the second is transition briquetting, and stable briquetting.
As the pressure is low in the first two steps and the density will increase
quickly when the pressure is increased. While in the third step, the density
will increase slowly along with the pressure.
The
briquette and pressure keeping time
The
pressure has its own effect on the quality of briquette when it`s small while
it affects little when it`s big. It has been seen that the quality of affection
can be ignored if the pressure-keeping time is more than 40 seconds. On the
other side if the pressure keeping time is more than 20 seconds, an extra 10
seconds on pressure keeping the briquette density by 5%.
Raw
material type
In
different briquette methods, different kind of raw material is needed. Some raw
material such as wood type, straw, etc. is good to briquette with the heating
system. As the lignin create a well performance on the high temperature which
highly enhancements the plasticity.
The
moisture of the raw material
The
density relaxation and burning effect of the biomass briquette are affected by
moisture. Raw material with appropriate moisture will get an ideal briquette
effect. Suitable moisture will help to pass pressure on the particle and a well
lubricating. But the biomass that we get has moisture around 20-40%. The first
part of the briquette energy will cost extra and useless moisture when
briquette with high moisture. The raw material having low moisture is not
suitable for lignin plasticization.
Crushed
size of the raw material
The
quality metrics of the biomass briquette are affected by crushed size-fall
resistanceand density relaxation. When the raw material is introduced in a
certain type of briquette machine, the size of the raw material must be smaller
than the mould briquette output whole size. The raw material which is
unsuitable in size, especially different in size and shape and will make the
briquette with crack. The raw material will affect the strength of the biomass
briquette. When the raw material is big, it will decrease the effectiveness of
the briquette machine and also upturn the power consumption.
The
Final word
These
days biomass briquette making has become more popular
with the development of renewable energy. This is all about Biomass Briquette Machine and tips to improve
biomass briquette quality. Biomass waste recycles plant helps to make a good
profit and also protection for the world`s environment today and onwards.
