The simple answer is no, each raw material has its own combustion characteristics. These characteristics range from changes in ash content to possible clinker and slag formations and corrosion risks due to sculpture and chloride content. Different makes and designs of pellet stoves and boilers are produced to handle different levels of ash and corrosion risk. Wood pellets generate the lowest ash content, and also have the lowest corrosion risk for the stove or boiler. Other biomass fuel pellets such as straw and grass pellets can generate higher levels of ash, and pose a higher corrosion risk to the pellet combustion chamber. Grass and straw pellets however are much cheaper to produce, so much lower fuel costs are possible.
