produces significant air pollution and is generally associated with significant heat
losses, even despite thermal insulation of steam
Both, distribution network and injection wells lead to the heat loss. In some
cases the heat loss can be as high as 1/3rd. On the Fig. 8.4 there is an example of
steam generator unit closely placed to the injection well in order to avoid heat
losses in the distribution network.
