This study provides an indepth analysis of the distribution characteristics, combustion characteristics, and energy utilization potential of wheat root stubble resources in Henan Province through comprehensive research, experimental testing, and statistical analysis. The results showed that the total theoretical amount of wheat root stubble resources in Henan Province was 54.304 million tons, and the total amount that could be collected was 39.642 million tons, which could be converted to 23.911 million tons of standard coal, among which the root stubble resources in the four cities of Zhumadian, Shangqiu, Zhoukou, and Nanyang were more abundant, accounting for about 1/2 of the total theoretical amount of root stubble resources in Henan Province; The industrial analysis of wheat stubble samples from different areas in Henan Province showed that the ash content was 10.3%~16.3%, the volatile content was 62.8%~69.1%, the fixed carbon content was 8.50%~14.74%, and the calorific value was 17.10~18.31 MJ/kg, and the total heat of wheat stubble fuel for possible resource utilization was 6.99×10¹¹ MJ. The preliminary analysis of the distribution and energy utilization potential of wheat root stubble resources can provide an important reference and basis for the rational development and utilization of wheat root stubble resources.
