The invention relates to a steam generator (D1, D2) having a first passage, which is formed by one or more pipes (R1, R2) and through which a medium can be conducted in liquid and/or vapour form, and having a second passage (F1, F2), through which a hot gas can be conducted along the outer side of each of the pipes (R1, R2) which form the first passage. Each of the pipes (R1, R2), which form the first passage, of the steam generator (D1, D2) is surrounded by a pressure-resistant casing (M1, M2) which has a heat-insulating coating (W1, W2) on the inner side thereof and through the interior space of which the second passage (F1, F2) runs. |
