Direct-flame afterburners are the most commonly used air pollution control device in which combustible aerosols, vapors, gases, and odors are to be controlled. The components of the afterburner are shown in Fig. 29-15.

Friction factor in long steel pipes handling wet (saturated with w ater vapor) gases such as hydrogen, carbon monoxide, carbon dioxide, nitrogen, oxygen and similar materials should be considered carefully, and often increased by a factor of 1.2 to 2.0 to account for corrosion.

The orifice area of these devices (see illustrations) is at the outlet end of the SRV nozzle through which the discharging vapor/gases/liquids must pass. These values are identified in industry as (valve body inlet size in.) X (orifice letter) X (valve body outlet size, in.). For example, a valve would be designated 3E4.

Flares are an attempt to deliberately burn the flammable safety relief and/or process vents from a plant. The height of the stack is important to the safety of the surroundings and personnel, and the diameter is important to provide sufficient flow velocity to allow the vapors/ gases to leave the top of the stack at sufficient velocities to pro ide good mixing and dilution after ignition at the flare tip by pilot flames. 

Determine flare stack height above ground (grade) Refer to Figure 7-73. Based on the mach velocity of the vapor/gases lea ing the top dp of the flare stack (see Equation 7-76), determine the mach number, e.g., 0.2, then from Figure 7-73 ...

Fire protection systems achieve prevention of fire by operating until flammable vapor, gases, or hazardous materials dissolve, dilute, disperse, or cool.
