Sunflower husk pellets can be a good alternative to wood fuel. They are commonly used in biomass power plants and industrial boilers. Sunflower husk pellets typically have an ash content of 2-3%, while the ash content of wood pellets is 1-1.5%. However, due to their more attractive price, sunflower husk pellets are increasingly used for co-firing with wood pellets to achieve a better balance of cost and energy efficiency. Sunflower husk pellets are an environmentally clean fuel. The amount of CO2 released during combustion is comparable to the amount released during natural decomposition.
