Binders for pellets from biomass
BARTOŠ, Pavel
Pellets from biomass represent an appropriate form of biofuel for combustion. They are characterized by good fuel parameters, they enable efficient storage, transport and handling, and automatic fuel supply to the combustion chamber. Pellet production is quite a complicated and energy-consuming process. During the production it is necessary to ensure that the amount of input energy was the same or even smaller than the energy obtained. To streamline the production and improve thermo-mechanical properties some binders and additives can be used. It is possible to increase the strength, density, calorific value and resistance to abrasion by using such binders and additives, in addition, you may achieve changes in characteristics and quantity of ash, decrease of the cost of pellets production, the use of materials which are separately difficult to burn and not easy to process by pelleting and affecting emission parameters during combustion. The most important binders and additives with a positive effect on pellets include: lignin, starch, molasses, glycerol, paraffin and palmitin, carboxymethyl cellulose, limestone, rye and corn flour, lignosulfonate and waste potatoes.
