4.6.1 Various industries The minimum allowable height of the furnace smoke window (or exhaust pipe) is 15m. 4.6.2. For industrial furnaces that are newly built, renovated or expanded since January 1, 1997 and emit smoke (powder) dust and harmful pollutants, the minimum allowable height of smoke (or exhaust pipe) shall be in accordance with 4.6.1 In addition to the provisions of 4.6.3 and 4.6.3, the requirements of the approved environmental impact report should also be determined. 4.6.3 When there is a building within a radius of 200m around the bacon (or exhaust pipe), the provisions of 46.1 and 46.2 should be followed. The flue (or exhaust pipe) should also be more than 3m higher than the tallest building. 4.6.4 If the height of various industrial furnace smoke brushes (or exhaust pipes) does not reach 4.6.1, 4.6.2 and 4.6.3, the maximum allowable emission concentration of smoke (powder) dust or harmful calcium substances shall be 50% of the corresponding regional emission standard value. 4.6.5 Starting from January 1, 1997, permanent sampling, monitoring holes and platforms for incoming sample monitoring will be installed in newly built, renovated or expanded industrial security smoke stations (or exhaust gas logs).
5 Monitoring
5.1 Test conditions, the test is conducted under the maximum heat load. When the furnace density does not reach or exceeds the design capacity, it must also be measured under the heat load of the maximum production capacity. , that is, it is carried out during the stable heating stage when fuel consumption is large. The general auxiliary test time shall not be less than 2h5.2. The measured smoke (powder) dust and harmful pollutant emission concentration of industrial furnace density should be converted into the specified air connection coefficient. Or the value when the excess air coefficient is:
Cupola (cold blast furnace, blast temperature ≤ 400℃) air mixing coefficient is specified as 4.0 Cupola (hot blast furnace, blast temperature > 400°C) air carrying coefficient is specified as 2.5: The excess air coefficient of other industrial furnaces is stipulated as 1.7 for smelting furnaces, and the iron ore sintering furnace is connected to a measured concentration meter. 5.3 The monitoring point for unorganized emission dust and production dust shall be set at the emission outlet of the door and window of the factory building where the industrial furnace is located, and the maximum rolling value shall be selected. If the industrial furnace is installed in the open air (or has a roof but no walls), the monitoring point should be selected at any high point 5m away from the smoke (inspection) source and the minimum height is 1.5m, and the maximum tension value should be selected, ||tt| |6 Standard Implementation
6.1 This standard is supervised and implemented by the environmental protection administrative department of the people's government at or above the provincial level. 6.2 Various industries located in the melting rain control area and the dioxide pollution detection rack control area approved by the State Council In addition to complying with this standard, the emission of furnace density and SO should also comply with the total quantity control standard.
