How long can the pellets produced by the biomass pellet machine burn?

How long can the pellets produced by the Biomass Pellet Machine burn? It is not certain how long the pellets can burn. The pellets burned in different combustion methods and in different burners are different. The same weight of coal and straw cannot be said to be longer. It is also related to the combustion method and the burner. .
The current combustion methods mainly include the following:

1. Layered combustion. Laminar combustion, also known as fire bed combustion, is only suitable for solid fuels and is the main combustion method for small boilers. Layered combustion has a wide range of adaptations, but the air and the combustion material are poorly mixed, the combustion reaction is slow, and sometimes black smoke occurs.

2. Suspension combustion. Suspension combustion, also known as fire chamber combustion, is suitable for solid, liquid or gas fuels and is the main combustion method for large and medium boilers. Suspension combustion does not require a grate, the fuel and air contact area is large, the fire is rapid, the burnout rate is high, the combustion efficiency and the thermal efficiency of the boiler are high, and automatic control can be realized. However, there are many equipments, complex systems and high energy consumption.

3. Boiling and burning. The combustion material is crushed into particles smaller than 2mm and sent to the furnace, and the air enters from the air cap on the air distribution board, causing the coal to roll up and down and burn in a state similar to liquid boiling. Boiling combustion equipment has large heat storage and strong combustion reaction. The combustion temperature of this method is below 900 degrees, which can greatly reduce the formation of nitrogen oxides, a serious carcinogen, and can easily take desulfurization measures, which is conducive to environmental protection, so it has great prospects for development.
