The biomass pellet fuel produced by the TONY biomass pellet machine is a new type of environmentally friendly fuel that has been vigorously developed in recent years. Biomass pellet fuel mainly utilizes agricultural and forestry wastes such as sawdust, straw, rice husks, and peanut shells, which are formed into a kind of pellet biomass fuel through the pellet machine.
When using biomass pellet fuel, the most frequently asked question is what is the calorific value of the biomass pellet fuel? To answer people's questions, TONY pellet machine manufacturer has summarized two influencing factors of the calorific value of biomass pellet fuel.
1.The raw materials of the fuel determine the approximate range of calorific value of biomass pellet fuel
The raw materials of biomass pellet fuel determine its calorific value. Generally, there are many raw materials used to make pellet fuel. It is precisely because the raw materials are abundant and renewable that biomass pellet fuel has the renewable property.
These raw materials can be roughly processed into the following several common types of biomass pellet fuels: Biomass rice husk pellets (calorific value 3000-3300 kcal /kg), biomass peanut shell pellets (calorific value 3500-3800 kcal /kg), biomass straw pellets (calorific value 3000-3200 kcal /kg), biomass miscellaneous wood pellets (calorific value 3800-4000 kcal /kg), biomass pine wood pellets (Calorific value: 41000-4500Kcal/kg), biomass Larch pellets (calorific value: 4200-4600Kcal/kg).
From the above-mentioned calorific values of several common biomass pellet fuels, it can be seen that the calorific value of pellet machine fuels is mainly determined by the raw materials. The calorific value of wood chip raw materials can reach about 4000Kcal/kg, and the lowest is that of straw raw materials, which generally reaches about 3000Kcal/kg.
2. The moisture content of raw materials has a slight impact on the calorific value of biomass pellet fuel
The calorific value of biomass pellet fuel is greatly influenced by the raw materials. So, what factors affect the calorific value of the same raw materials? Generally speaking, the amount of moisture in biomass pellet fuel relatively reduces the content of combustible substances. High moisture in biomass pellet fuel makes it difficult to ignite, affects the combustion speed and is prone to causing black smoke.
From the above two points, it can be seen that there are quite a few factors influencing the calorific value of biomass pellet fuel. In fact, the density and ash content of biomass pellet fuel also have an impact on the calorific value of biomass pellet fuel produced by pellet machines.
Why does density affect calorific value? Because biomass pellet fuel needs to release heat per unit volume when burning, if the biomass pellet fuel with low density is lighter in weight per unit volume, while the biomass pellet fuel with high density is heavier in weight per unit volume, the calorific value of the biomass pellet fuel with high density is naturally higher than that of the biomass pellet fuel with low density.
The influence of ash content on the calorific value of biomass pellet fuel is more difficult to understand. Between 1% ash and 4% ash, the calorific value of biomass pellet fuel with 4% ash is lower than that of biomass pellet fuel with 1% ash. With more ash, the weight of the combustible pellets is naturally smaller.
