Biomass fuel boilers are very popular with users, but often users can use more than one type of biomass fuel, such as bark, straw, peanut shells, sawdust, bagasse, etc. These fuels need to be co-fired and co-fired. The process requires a proper mixing ratio to achieve better combustion effect and high heating value.

Take sawdust, bark and straw as examples, the fuel ratio is as follows:

1) Mainly bark: bark: sawdust: straw=5:3:2.

2) Mainly sawdust: sawdust: straw: bark=6:2:2.

3) Mainly straw: straw: sawdust: bark=4:3:3.

The co-firing of biomass fuels should not only pay attention to the proportioning ratio, but also pay attention to correct operation. The biomass boiler should not be too wet during operation, and the materials should be mixed and mixed to achieve high heating value and moderate fuel particles. It can be proportioned according to the water content of the fuel. For example, the water content of the bark is about 30%, and the water content of the rice husk is about 12%, so that the bark and rice husk can be blended. At the same time, attention should be paid to the fuel operation in the water-cooled jacket, and the fuel ratio can be adjusted appropriately.
