Heating chamberconsists of a cowling, upper and lower tube plates with heating tubes expanded into them. Vapor, through branch pipesis _________to steam jacket and then via the split-like holes directly to the steam chamber. To ________vibration of the heating tubes the heating chamber is provided with welded tube plates inside it. The heating chamber has four access ports. Non-condensed gases are __________through ammonia withdrawals. In the lower part of the heating chamber above the lower tube plate two branch pipes are arranged for removal of condensate. Immediately under the ________chamber there is juice chamber. This chamber is ________of support with conical bottomin the center of which there is a pipe branchfor the removal of syrup to the next stage of the evaporation station. At the support part there are two _________and conical cowlings. In the bottom part of the chamber there are two pipesfor feeding syrup from the preceding unit andfor the removal of syrup for circulation to the upper part of the__________. Conical cowlinghas two pipe branches for removal of reheat steam from the_________. For separation of steam from the steam-and-syrup ________inside the juice chamber there is welded guide cone.
