In this regulation, the following terms are understood as follows:

1.3.1. Domestic Solid Waste (also known as household waste, hereinafter referred to as DSWSW) is solid waste generated from daily human activities.

1.3.2. Domestic Solid Waste Incinerator is a system of equipment for processing DSWSW through incineration accompanied by flue gas treatment systems.

1.3.3. Combustion Zone (or combustion chamber) includes areas using heat to burn DSWSW, comprising:

a) Primary Combustion Zone is the zone that converts DSWSW into gases and solids (ash, dust).

b) Secondary Combustion Zone is the zone that burns components of the gas stream escaping from the primary combustion zone.

1.3.4. Retention Time is the time it takes for the gas stream to flow from the inlet point to the outlet point of the secondary combustion zone at the temperature conditions specified in Table 1 of this regulation.

1.3.5. EMISSIONS Emission Gas

1.3.8. is the processing capacity of the domestic solid waste incinerator, measured by the maximum amount of DSWSW burned per hour (kg/h).³) Standard Cubic Meter of Emission Gas (Nm ^°is a cubic meter of emission gas at a temperature of 25

2. TECHNICAL REGULATIONS

2.1. C and an absolute pressure of 760 mm of mercury.

Basic Technical Requirements for Domestic Solid Waste Incinerators

2.1.1. The domestic solid waste incinerator must operate according to a multi-stage combustion process, ensuring the presence of a primary and secondary combustion zone. The volume of the combustion zones, capacity, and retention time of the domestic solid waste incinerator shall be determined in accordance with the guidelines provided in the Appendix attached to this regulation.

2.1.2. Measures must be taken to limit emissions escaping into the environment through the waste feed door.

2.1.3. The chimney of the domestic solid waste incinerator must meet the following requirements:

a) The height of the chimney must be calculated to ensure environmental quality requirements when emissions are released into the atmosphere, but must not be less than 20 (twenty) meters above ground level. In cases where there are fixed obstacles within a radius of 40 (forty) meters from the base of the chimney affecting the dispersion of emissions, the chimney must be at least 03 (three) meters higher than the highest point of the obstacle;

b) The chimney must have a sampling port with a diameter or width of each side ranging from 90 (ninety) mm to 110 (one hundred ten) mm, equipped with a cover to adjust the opening size, along with a safe and convenient operating platform for sample collection. The sampling point must be located between the following two positions:

- Lower position: Above the highest point of the connection between the flue gas treatment system and the chimney by at least 08 (eight) times the largest internal diameter of the chimney;

- Upper position: Below the mouth of the chimney by at least 02 (two) times the largest internal diameter of the chimney from the mouth of the chimney.

2.1.4. During normal operation, the basic technical parameters of the domestic solid waste incinerator must comply with the provisions set out in Table 1 of this regulation.

Evaluation of this parameter only applies during inspections to confirm compliance with environmental protection requirements for the waste treatment facility.

2.1.5. No external air should be mixed with the exhaust gas from the outlet of the secondary combustion zone to dilute the exhaust gas up to a height of 02 (two) meters above the sampling point.

2.1.6. The incinerator must have a flue gas treatment system with an operating process including the following main stages:

a) Heat reduction (rapid cooling);

c) Treat harmful components in exhaust gas.

The processes mentioned above shall be carried out separately in each device or combined simultaneously in a single device.

2.1.7. In cases where the distance from the waste feed door to the farthest point of the primary combustion zone of the CTRSH incinerator exceeds two (2) meters, mechanical equipment for feeding and mixing CTRSH in the primary combustion zone (except in special technological cases that do not require mixing such as gasification) and a mechanical system for removing ash must be installed.

2.1.8. The CTRSH incinerator must have a bypass valve to discharge exhaust gas directly through the chimney without passing through the exhaust gas treatment system when there is an accident with the exhaust gas treatment system. The bypass valve must have a manual or automatic control lever at a height convenient for standing persons, ensuring easy and timely operation during accidents without having to climb onto the CTRSH incinerator. Waste feeding must be immediately stopped after using the bypass valve.

2.2. Maximum permissible values for pollutant parameters in exhaust gas from solid waste incineration.°seals must be kept confidential in accordance with the regulations of the State, the Ministry of National Defense, and the regulations of the unit.

During normal operation, the maximum permissible values for pollutant parameters in exhaust gas from CTRSH incinerators are calculated according to the following formula:

C_max TTĐ x K_v

Where:

Ministry of Science and Technology: The Minister and Deputy Ministers, agencies and units under the Ministry;_max is the maximum permissible value for pollutant parameters;

- C is the concentration of pollutants specified in Table 2 of this Standard;

- K_v is the area factor specified in Table 3 of this Standard.

a) The startup procedure for CTRSH incinerators must follow the sequence below (except for cases where the CTRSH incinerator has a special operating procedure specified by the manufacturer and approved by the environmental protection management agency):

3.1. - Step 1: Start the exhaust gas treatment system;

- Step 2: Start and dry all combustion zones;

- Step 3: Officially feed CTRSH into the CTRSH incinerator.

b) The shutdown procedure for CTRSH incinerators must be carried out in the following sequence:

- Step 1: Stop feeding CTRSH;

- Step 2: Stop the exhaust gas treatment system when the temperature in the primary combustion zone drops below two hundred (200) degrees Celsius.

3.1.2. CTRSH must be controlled before being fed into the CTRSH incinerator to ensure it does not affect the normal operation of the incinerator; do not feed into the CTRSH incinerator: explosive waste; corrosive waste; pesticide chemicals and chemical packaging; waste containing mercury, lead, cadmium exceeding hazardous waste thresholds.

3.1.3. Technical measures must be taken to remove ash from the primary combustion zone during operation in a convenient manner to ensure continuous operation of the CTRSH incinerator without interruption.

3.1.4. An operational logbook for the CTRSH incinerator must be established, recording the quantity, duration of operation, operator's name, and temperature at locations equipped with temperature measuring devices. ^°C.

Monitoring of solid waste incineration

3.2.1. The CTRSH incinerator must be equipped with temperature measurement and display devices in all combustion zones. For incinerators with a capacity of 500 kg/h or more, temperature measurement and display devices for flue gas must be installed immediately after the heat exchanger.

3.2.2. Regular environmental monitoring of CTRSH incinerators must be conducted in accordance with current regulations and requirements of environmental management agencies.

3.2. METHODS OF DETERMINATIONperiodorganize credit institutions, foreign bank branches are responsible for organizing the implementation of this Circular.
