“…According to research, each 2 tons of straw heating value is equivalent to 1 tons of standard coal, and its average sulfur content is only 0.38%, and the average sulfur content of coal around 1% [25].Thus, we can see that the straw energy-oriented use both reduced the use of coal, and found new ways for China's energy crisis.Moreover, straw energy-oriented use can bring economic, social and environmental benefits [26,27]. Honglei Wang [28] research shows that the development and utilization of straw energy is a good people's livelihood engineering, energy conservation and emissions reduction, and promote environmental protection.Chengmao Cao [29] research shows that development of straw energy-oriented use, it is reasonable and efficient use of resources, alleviate the pressure of the current our country energy, low carbon economy development, promote the sustainable development important constituent, but also promote the adjustment of energy consumption structure, transforming economic growth mode, establish environmental friendly and resource-conserving society effective measures.…”
