Hanoi-Vietnam: Parameters required for domestic solid waste incinerators

05:31, 11/07/2024

The content is stipulated in Circular 03/2016/TT-BTNMT issued by the Vietnam Ministry of Natural Resources and Environment on March 10, 2016, which regulates domestic solid waste incinerators.

Circular 03 stipulates that during normal operation, the basic technical parameters of domestic solid waste incinerators in Vietnam must meet the requirements in the following table:

Table of Basic Technical Parameters of Domestic Solid Waste Incinerators

No.	Parameter	Measurement unit	Required value
1	Capacity of the DSW incinerator⁽¹⁾	kg/h	≥ 300
2	Temperature at the primary combustion chamber ⁽²⁾	⁰C	≥ 400
3	Temperature at the secondary combustion chamber	⁰C	≥ 950
4	Retention time	s	≥ 2
5	Temperature of flue gas (measured at the sampling porthole)	⁰C	≤ 180
6	Residual oxygen (measured at the sampling porthole)	%	6 - 15
7	Temperature at the outside of the DSW incinerator (or the thermal barrier coating)	⁰C	≤ 60
8	Uninterrupted operation ability (while mechanical stability and technical parameters are ensured) ⁽³⁾	h	≥ 72
*Notes:* ⁽¹⁾ Capacity of 300 kg/h is equivalent to the minimum volume of the primary combustion chamber is 2.4 m³. ⁽²⁾In special cases (such as anaerobic thermal combustion), the secondary combustion chamber may operate at a temperature of below 400 ^oC provided that trial operation meets requirements specified in Section 2.2 of this Regulation and such operating temperature is certified to meet environmental protection requirements for DSW treatment facilities by a competent authority. ⁽³⁾The assessment of this parameter is applied to the certification of satisfaction of environmental protection requirements by a DSW treatment facility.

Details may be found in Circular 03/2016/TT-BTNMT effective May 1, 2016.
