Many people have asked such a question: How long can biomass pellets burn exactly? The answer is uncertain. Under different combustion methods, the combustion time of the pellets in different burners varies, and at the same time, the inherent characteristics of the biomass pellets also affect the combustion time.
1. Moisture
Generally speaking, the presence of moisture relatively reduces the content of combustible substances in biomass and lowers its calorific value. High moisture content may make ignition difficult and affect the burning speed.
2. Volatile matter
The volatile matter and calorific value in biomass pellets have a significant impact on both ignition and combustion conditions. For volatile matter with high calorific value, the initial temperature is also high. When pellet fuel is heated, the volatile matter is released first and catches fire and burns.
3. Ash content
Ash is the non-combustible component of biomass briquette fuel. The higher the ash content, the relatively less combustible components there are, the relatively lower the calorific value, and the lower the combustion temperature.
4. Geometric characteristics and molding pressure of biomass briquette fuel
The time it takes for a particle to burn out is proportional to the square of its diameter; that is, the coarser the particle, the longer the burning time.
Granular fuels with high porosity are relatively easier to burn and have good combustion performance. Pellet fuel with low porosity has poor combustion performance.
The TONY pellet machine can press different types of raw materials into cylindrical pellets of 1.1-1.3g/cm³
5. Combustion time and combustion efficiency
The duration of the combustion of pellet fuel is not related to the combustion efficiency. The greater the particle density, the longer the combustion duration.
Combustion efficiency is not measured by combustion time, but by the price per unit calorific value. Simply put, the efficiency of combustion is measured by the cost of generating the same amount of heat.
Biomass pellets are suitable for households, small and medium-sized power plants, and boilers, with a calorific value ranging from 19,000 to 21,000 kJ /kg. Among the new clean energy sources, its cost-effectiveness and practical performance are significantly better than those of natural gas, electricity and other energy sources.
Choosing a biomass pellet machine produced by a high-quality pellet machine manufacturer is the prerequisite for pressing high-quality biomass pellets. Only a high-quality biomass pellet machine can operate stably and continuously and produce biomass pellets with high density. It is suggested that you consider the TONY biomass pellet machine manufacturer. TONY pellet machines have considerable experience in the industry and are highly praised among customers.
