Abstract: Smoldering experiments of wheat straw, corn stalk, sorghum stalk, sweet potato vine,cotton stalk and millet straw have been conducted on STA. Results showed that smoldering of agro-stalks can be divided into four stages: biomass heating up, carbonization, char oxidation of and ash heating up. The reaction heat of carbonization processes of the above agro-stalks was 6.285, 5.269, 5.308, 4.041, 5.347, 5.414 kJ per gram consumed matter respectively. The reaction heat of char oxidation was 22.554, 20.723, 24.392, 24.319, 26.105, 19.477 kJ per gram consumed matter,respectively.

Key words: agro-stalks, smoldering, heat emission characteistics
