摘要:
Composite tube for heating gases to very high temperatures, in particular for generating steam, comprising at least one internal combustion or heating tube (6), an external reinforcement (3) which surrounds the internal tube (6) and spacer means (2, 5) for separating the internal tube (6) from the external reinforcement, in which the materials of the internal tube (6) are resistant to the milieus of the heating gases coming into contact with this tube. A jacket tube (1) may be placed between the internal combustion or heating tube (6) and the external reinforcement (3). In the composite tube of this invention the heating tube wall thickness can be reduced and higher temperatures and heat flows can be achieved than hitherto possible.
摘要:
Connection system for a large number of similar apparatuses (A), connected in parallel to a common primary collecting set of inlet and outlet tubes (1, 2, 3), such as a header system. In order to increase the capacity use is made of a plurality of common secondary collecting sets (10, 11, 12), branching off from the primary collecting set (1, 2, 3), in which a certain number of apparatuses (A) is connected in parallel to each secondary collecting set (10, 11, 12), which apparatuses are installed in a single row at the side of said secondary collecting set (10, 11, 12).
