How to choose good quality biomass pine wood pellet mill machine and China professional wood pellet machine factory?

professional design biomass wood pellet machine for Indonesia market

Does the price of biomass fuel machinery have any bearing on the loss of biomass pellet fuel plants? The price of biomass fuel machinery is too high and the cost is difficult to recover. If the price is too low, the quality is not guaranteed. So how do we choose the appropriate professional design biomass pine wood pellet machine ?

An example:

There is such a friend. His 5 ton per hour pine wood pellet plant was built in 2016. At that time, the pine wood pellet production line he invested in included 2 sets of 2-3 ton per hour pine wood pellet making machines, but the cost of his investment was a bit high,around 2 million yuan, nearly 300,000 US dollars. But be aware that this is in the 2016 economic environment. What he considered at the time was to choose a high-quality biomass pellet machine manufacturer. As a result, he chose an internationally renowned pellet machine manufacturer "C". After several years of use, he found that he had purchased an expensive 2-3t/h pine wood sawdust biomass wood pellet mill. It's just that the price is expensive, quality and price are not directly proportional, the maintenance rate is still very high, and maintenance is a large investment, and then in order to solve the drying problem of raw materials, he invested another 600,000 yuan (about 80,000 US dollars) ) Purchased one set of biomass pine wood sawdust drying equipment. The investment in pine sawdust dryer machine has increased the investment in the overall 5 ton per hour pine wood pellet processing line. Therefore, the cost of biomass pine wood pellet fuel will increase.

This friend has invested 5 years of energy in this 5 ton per hour ring die pine wood pellet making line. When the business ended, he did not make any money at all, but barely recovered the cost. Finally, he became an "expert" in the maintenance and construction of biomass pellet machines. Now as long as you have questions about the biomass pine wood pellet production line or how to arrange the biomass pellet production line, he can give you a simple solution.

In fact, some people may ask, isn't the market for biomass pellet fuel very good? Why is it not profitable? Indeed, the market for biomass pellets is very good, and there are many types of biomass and a wide range of uses, making it a very promising industry. However, the quality of the pellets, the price of pellets, sales issues, investment cost , equipment , process , etc., will all have an impact. Under normal circumstances, even if a layman wants to invest in this industry, as long as all aspects are well controlled, it is very simple to make a profit.

Through his investment experience, we have summarized the following suggestions for everyone:

(1) The price of biomass fuel machinery is too high, and the payback period is too long, and the risk is much greater. When investing in a biomass pellet plant, investment in equipment should not be too large. But quality is the most important thing. A good quality granulator will greatly reduce the cost of later input.

(2) The maintenance of the biomass pellet machine is very important.

(3) Dryers should also pay attention to quality, but as far as the current market is concerned, many medium-priced dryers are very suitable, and it is not necessary to pursue world-renowned brands. Because the process technology and equipment quality of many Chinese dryer and granulator manufacturers are very good, and the cost performance is very high, the maintenance rate is low, and the after-sales service is good. More importantly, the equipment has a long service life and is very durable.

(4) The sales can only be realized, so the sales link is also very important.

Do you really understand pine wood pellets?

1. The calorific value of pine biomass pellet fuel

What is the calorific value of pine biomass pellet fuel? What is the calorific value of biomass pine pellet fuel, and how much is the calorific value of high-quality pellets? With these questions in mind, let's learn about the calorific value of biomass fuel.

(1) What is the calorific value of pine biomass pellet fuel?

The calorific value of pine biomass pellet fuel is also called the calorific value of pine biomass pellet fuel. It has high heating value (HHV) and low heating value (LHV). The heating value is an important indicator to measure the combustion performance of a biomass fuel. The high calorific value refers to the total heat that can be produced after a unit mass of fuel is completely burned, including the latent heat of vaporization of the moisture in the combustion product (flue gas); the exhaust temperature of general combustion devices such as boilers is greater than 100 degrees, and the moisture in the flue gas In the state of steam, the water vapor absorbs the latent heat of vaporization from the heat released by the combustion of the fuel. Therefore, after deducting this part of the latent heat of vaporization from the high calorific value of the fuel, the combustion equipment can finally use the heat. This heat is called the fuel Low calorific value, that is, low calorific value. Therefore, the thermal calculation of combustion equipment is based on the low calorific value (calorific value).

(2) Calculation method of calorific value of pine pellet fuel

The difference between the high and low calorific values ​​of the same fuel is only the latent heat of vaporization absorbed by water vapor. Considering that the water vapor in the flue gas is composed of two parts of moisture, that is, the inherent moisture in the fuel and the moisture formed by the combination of hydrogen and oxygen, and the latter consists of the following chemical reaction H2+1/2O2→H2O

It can be seen that after 1kg of hydrogen is burned, 9kg of water is produced, so 1kg of fuel is burned to produce (9H/100+M/100)kg of water. In the formula, H and M respectively represent the mass percentage of hydrogen element and the mass percentage of water in the fuel. If the latent heat of vaporization of 1kg of water is approximately 2508KJ at normal pressure, the relationship between the high and low heating values ​​of the same fuel is LHV=HHV- 2508(9H/100+M/100)=HHV-25.08(9H+M)(KJ/kg).

(3) What is the calorific value of pine pellet fuel?

The above explained the concept and calculation method of the calorific value of pine wood pellet fuel. So what is the calorific value of pine wood pellet fuel material? According to the test report issued by a regular biomass fuel inspection agency, the calorific value of the pine biomass pellet fuel we are talking about today is the low calorific value of the pine pellet fuel alone. The low calorific value of pine biomass pellet fuel is 17.09MJ/kg, which is 4084 kcal/kg when converted into kcal.

2. Can pine pellets distinguish good quality from bad by color?

(1) The color of pine pellet fuel cannot determine the fuel quality

In fact, the simplest truth is that pine wood pellet fuel is a fuel that is used for burning. We cannot judge the quality by looking at the appearance. The advantages of this judgment are arbitrary. In other words, isn’t the coal burned before also black? Is the black and light coal a poor quality coal? Obviously, such a statement is untenable. Today we will tell you that the color of the appearance can only reflect a part of the quality of pine pellet fuel. In fact, we judge the quality of pine pellet fuel. Good or bad, we must judge by the following aspects.

(2) How to judge the quality of pine wood pellets?

The quality of pine pellet fuel is determined by calorific value, ash content, moisture, and degree of forming. In fact, the most scientific judgment is to observe the production raw materials and processing sites of pine pellet fuel, and monitoring reports.

①Raw materials

The raw materials of pine wood pellets are generally pine wood. Pine wood generally includes white pine, red pine, mongolica, etc., and it is mixed with a small amount of other wood materials. Therefore, if the formula of the raw material is different, the color of the produced particles will be different. Therefore, we mainly judge the ash content of the basic pellet products based on the cleanliness of the raw materials produced, and the ash content is a factor that affects the coking degree of pine pellet fuel combustion.

②The molding compression ratio of the pine wood pellet press machine

By observing the model of the pine wood pellet molding machine, we asked about the usage of the abrasive tools. Generally, the new mold made at the beginning has a tighter molding degree of the pressed pellets. When the mold is quickly changed later, the pellets are compressed a little more and the pine is pressed. And tightness has little effect on the quality of pine pellets, but extremely irregular pellets indicate poor quality.

③The quality is judged through the laboratory report issued by the professional structure

This method is the most convincing. Generally, the calorific value of high-quality pine wood pellet fuel is 4200-4500 kcal/kg, the ash content is about 2, 3, and the moisture content is less than 10. The quality of such pine pellet fuel is high-quality and suitable for biomass burners. Material steam generators and other stoves, of course, the best and most expensive pure Pinus sylvestris particle ash content is less than 1, this is suitable for fireplace use.

The above content can not only help those who want to purchase pine wood pellets, but also remind biomass pine wood pellet fuel manufacturers to strictly process pine wood pellets and process high-quality pine wood pellets. Therefore, the regular pine wood pellet manufacturers will definitely have a regular test report, and they can also send samples for testing as required.
