Sunflower shells are the by-product of the de-hulling of sunflower seeds before oil extraction. They can be burned as fuel to power sunflower oil mills but because sunflower hulls are light in weight and low in bulky density, they are not good for burning directly in boiler and stoves. However when converting sunflower hulls into fuel pellets by sunflower hull pellet machine, the sunflower oil mills can make the most of sunflower hulls as solid biofuel and at the same time reduce the energy cost by using these low cost sunflower hull pellets to substitute the high price coal.
