VHI-18B incinerator has been put into use in Ninh Thuan, Bac Kan General Hospital, Tuberculosis and Lung Disease Hospital of Thai Nguyen, Bac Ninh, Son La provinces, Luong Tai district health center, Gia Binh, Que Vo (Bac Ninh), Sa Thay District Medical Center, Dac Ha (Kom Tum), Your National House printed money.

VHI-18B toxic solid waste incinerator is designed on the basis of applying the principle of multi-regional combustion currently used in advanced countries around the world. Solid waste is put into the primary combustion chamber maintained at a temperature of about 800 degrees C.

The air is continuously supplied during the incineration process. Smoke emitted from the primary combustion chamber (unburnt combustion products, dusty and toxic chemicals) is mixed with air according to the principle of a cyclone and fed into the secondary combustion chamber.

In secondary combustion chambers, incomplete combustion products will continue to be decomposed and burned at high temperatures (1050-1200 degrees C) with a sufficiently long combustion time (1.5-2 seconds). The smoke from the secondary combustion chamber is passed through the exhaust treatment system to eliminate dust, heavy metals and gas components that pollute the environment.

Features of VHI-18B burner, automatic control of combustion cycle, temperature, air supply mode and associated equipment. Smoke after treatment is colorless, odorless, does not cause environmental pollution, and meets TCVN 6560-1999 standards, which have been verified by functional agencies. In particular, the incinerator system has lower equipment costs than imported equipment, simple and safe operation.
