Introduction on Technical Process

The biomass feedstock is continuously fed into the gasifier by the feeding system to have pyrolysis and gasification reactions with pure oxygen and water vapor added by the fan at the bottom of the gasifier. The energy generated keeps the system running in a stable state, and the biomass is efficiently converted into biogas. The unreacted residual carbon is carried out of the gasifier along with the biogas. The residual carbon is separated and collected by the primary cyclone separator for gas-solid separation, and then re-sent into the gasifier through the back feeder installed at the bottom of the cyclone separator for further gasification. The ash and slag that are fully reacted are separated by the secondary cyclone separator and cooled by the ash cooling screw conveyor before being discharged and collected. Since no air is added to the gasification bed, the dilution of the fuel gas by a large amount of nitrogen is avoided, thereby obtaining high-quality synthesis gas. The high-quality synthesis gas undergoes an incomplete combustion reaction with pure oxygen in the tar cracking unit to achieve the cracking of tar and macromolecular hydrocarbons. The waste heat of biogas from the tar cracking unit is recovered by gas preheaters, steam heat exchangers, waste heat boilers and other equipment. Then it enters the gas cabinet after gas dust removal and  pressurization. The treated biogas is used to extract hydrogen or for chemical synthesis.
