Method of calculating heat exchange in the working zone of open flaring devices

A method is proposed for calculating heat exchange in the working zone of vertical and horizontal types of flaring devices (torches). The method is based on joint numerical solution of several associated problems, such as calculation of the length and dynamics of burning of a free flare, complex heat exchange and radiation characteristics in a multizone conical calculated region that approximates a flare (torch), local radiative heat flows from a randomly positioned multizone torch to elemental areas of a horizontal surface exposed to radiation, etc. The calculation method is approved on the example of a vertical gas field torch.
