Technical Drawing
English Manual
Advanced Engineer’s Control
Longlasting
Highly enclosed operation
Suitable for treating many kinds of MSW
Avoid secondary pollution
Simple operation
Gasified incineration is beneficial for burning many kinds of waste
Both gas motivated and oil motivated are all can be customized according to the customer’s needs.
Gasified incineration can burn all the daily waste.
Gasified incineration, mixed incineration ensures low emission standards of dust, dioxin, etc.
Completely enclosed operation is recommended for treating infectious waste to avoid secondary pollution
Compact structure and less land business
