Furthermore, after investigating the thermal properties of wheat straw ash from combustion, Du et al. (2014) suggested that the weight loss above 1000 °C might be attributed to the decomposition of relatively stable K-bearing species such as K 2 SO 4. Besides, K 2 SO 4 can react with H 2 O according to reaction 2 (Knudsen et al. 2004).

Miscanthus × giganteus - Wikipedia

Miscanthus × giganteus, also known as the giant miscanthus, is a sterile hybrid of Miscanthus sinensis and Miscanthus sacchariflorus. It is a perennial grass with bamboo-like stems that can grow to heights of 3–4 metres (13 ft) in one season (from the third season onwards). Just like Pennisetum purpureum, Arundo donax and Saccharum ravennae, it is also called elephant grass.
