Abstract: With increasingly severe stress in environmental situation，application research of biomass pellet fuel and equipment has become important in solving environmental pollution and energy problems.At present，diseases，insects，and weeds affect agricultural productivity，resulting in a reduced crop yield and quality.However，long-term use of pesticides and uneven artificial applications of pesticides has brought a huge pollution to soil and groundwater resources.Flame insecticide rotary tiller and biomass particle combustion were studied through an innovative theoretical design of flame disinfection rotary cultivator.This design provided a new research idea for application of biomass pellet fuel.
