Vertical Rotary Thermal Gasification Technology
The independently researched and developed Vertical Rotary Thermal Gasification Technology of the company has received multiple national patents and has passed the environment protection technology result evaluation of the country, and recommended by China Association of Environmental Protection Industry to apply for the National Environmental Protection Department’s First Award of Science and Technology, and is the only company that‘s involved in the drafting of the “Industry Standards of the National Vertical Rotary Thermal gasification Equipments”.
Because of the unique environment protection advantages ,such as “high thermal efficiency, higher temperature in the primary combustion chamber , lower loss of ignition, lower dust emission, lower concentration of dioxine emission”, and the economic benefits of this technology, such as “simple and impact furnace structure, convenient to start or stop the furnace and maintain, lower running energy consumption, light-weighted, small footprint, lower construction and operation as well as mainteniance cost.” has become the ideal solution for medium and small size solid waste gasification disposal.
The ECO-WASTE Vertical Rotary Gsification Technology is mainly made up by the gasifier (the primary chamber) and the secondary chamber (syngas chamber). The Vertical Rotary design makes the gasifier body and the grate can rotate into the same or diferent directions, which enable an evenly waste distrubtion for the whole chamber and continuous slag discharging.
Different from traditional incineration technology, ECO-WASTE’s two-stages manner will gasify the solid waste to produce the combustible syngas (synthesis gas) in the primary combustion chamber and then burn the syngas in the secondary combustion chamber. As it is burn the syngas rather than burn the waste directly, this procedure can secure the occurrences of the harmful elements especially like fly ash, nitrogen oxides, dioxin in a very low standard. The vertical rotary design makes the furnace body and the grate rotate relatively, which solves the technical problem on evenness of materials and continuous slagging. Moreover, it mixes wastes, which is helpful for gasification and sufficient combustion. As the slag has ceramic character, it enhances the integrated utilization of slag.
Advantages of Vertical Rotary Thermal Gasification Technology
The Vertical Rotary Thermal Gasification Technology is the most advanced and safest medium and small tonnage gasification disposal process, which is also the most welcomed new generation medium and small tonnage waste disposal technology in the country now.
In View of Environmental Protection:
- Two-stage-combustion processes ensure the complete combustion while produce less fly ash and fume (NOx, Sox, HCL etc.)
- High temperature and over 2s retention time in secondary combustion chamber, realize the less dioxin creation and emission
- Low loss on ignition and leaching toxicity
- The flue gas emission meet EU 2000 standard
- In View of Economic/Investment
- Compact structure requires less room and shorter construction period
- No complex pre-treatment system needed before the gasification process
- No additional fuel needed during the daily operation
- Less fly ash requires lower consumable consumption
- Can be applied for various solid waste disposal
- Long service life and easier to carry the maintenance
