Sunflower husk briquettes can be a good alternative to wood fuel. They are typically used at biomass power plants, as well as for industrial boilers. The ash content of sunflower husk briquettes is typically 2-3%, while that of wood pellets is 1-1.5%. However, due to their more attractive price, sunflower husk briquettes are increasingly being used for co-firing with wood pellets to achieve a better price-to-efficiency ratio. Sunflower husk briquettes are an environmentally friendly type of fuel. The amount of CO2 released during their combustion is comparable to the amount released during natural decomposition.
