NOVELTY - A heat generation method comprises (A) garbage fermentation and (B) biogas processing. The step (A) includes introducing garbage into 6 waste fermentation tanks, fermenting, storing, conveying gas, and recycling. The fermentation is carried out for 40-55 days at normal temperature and normal pressure for producing biogas. Filling device is mixed with air combustion. The temperature of stream is pre-heated to 100 degrees C. Turbine generating set scale of suction force and impact force driving device uses temperature difference and pressure difference of air flow generated by power generation.    USE - Heat generation method.    ADVANTAGE - The method has strong suction effect, and high conversion rate.    DETAILED DESCRIPTION - Heat generation method comprises (A) garbage fermentation and (B) biogas processing. The step (A) includes introducing garbage into 6 waste fermentation tanks, fermenting, storing, conveying gas, and recycling. The fermentation is carried out for 40-55 days at normal temperature and normal pressure for producing biogas. Filling device is mixed with air combustion. The temperature of stream is pre-heated to 100 degrees C. Turbine generating set scale of suction force and impact force driving device uses temperature difference and pressure difference of air flow generated by power generation. The power is sent to the control chamber. An INDEPENDENT CLAIM is included for a heat generation device which comprises bottom inner diameter greater than double layer chimney shaped hot air generating tower (1) diameter. The tower is connected with inner cavity of air inlet passage with outside atmosphere. Air inlet channel (2) is equipped with high speed wind turbine generating set I (3), where air inlet passage and hot air generating tower is connected with angle of 40-50 degrees . The generating tower is set under inner wall of the heater (4). The power generating tower is arranged above sealing cover (5). Hot air generating tower covers upper spirally arranged turbine generating set II.    DESCRIPTION OF DRAWING(S) - The drawing is a schematic diagram illustrating a heat generation device.
