What are the emission requirements for industrial boilers? Boiler low nitrogen emission standard
1. The particle emission requirements for newly built coal-fired boilers are 30mg/m, 200mg/m for sulfur dioxide, and 200mg/m for nitrogen oxides.
2. The particle emission requirements for newly built fuel boilers are 20mg/m, 100mg/m for sulfur dioxide, and 200mg/m for nitrogen oxides.
3. The particle emission requirements for newly built gas boilers are 20mg/m, 50mg/m for sulfur dioxide, and 150mg/m for nitrogen oxides.
4. The particle emission requirements for newly built biomass boilers are 20mg/m, 35mg/m for sulfur dioxide, 150mg/m for nitrogen oxides, and 200mg/m for carbon monoxide.
5. The particle emission requirements for coal-fired boilers in use are 30-50mg/m, sulfur dioxide 200-300mg/m, and nitrogen oxides 200-300mg/m.
6. The particle emission requirements for fuel boilers in use are 30mg/m, sulfur dioxide 100-200mg/m, and nitrogen oxides 200-250mg/m.
7. The particle emission requirements for gas boilers in use are 20mg/m, 50mg/m for sulfur dioxide, and 150-200mg/m for nitrogen oxides.
8. The particle emission requirements for biomass boilers in use are 20mg/m, sulfur dioxide 35-50mg/m, nitrogen oxides 150-200mg/m, and carbon monoxide 200mg/m.
9. When there are buildings within a radius of 200m for the chimney of a newly built boiler room, the chimney should be more than 3m higher than the highest building. The chimney height of a fuel and gas boiler should not be less than 8m according to the installed capacity of the boiler room.
