Reference standard: HG/T 20570.12-95 Flare System Settings P17 (411)
According to formula L thirty =L+10lg(WC two /2) Calculation
Where, L thirty Is the noise intensity at 30 m from the emission point, dB; L is the noise intensity, dB, which can be seen from Figure 1; W is the discharge flare gas flow, kg/s; C is the sound speed, m/s (for the calculation of C, see On line calculation program of sound velocity C in flare calculation )
Figure 1 (P R Is the ratio of upstream and downstream pressure of noise source)
