Steam Injectors for Vessel-Mounting
Mounting from Outside
For the heating of vessels by means of direct steam feed, since many years we have injectors in our program, which insert steam directly into the vessel, below the water-level. We would like to present hereby an advancement in this area. With the past models it is usually necessary that a person enters into the vessel by a man-hole to install the equipment within the tank.
With our again developed model for the assembly a free vessel standpipe or block flange is sufficient. Its nominal size must be one step larger concerning its dimension than the appropriate type of injector. With injector size DN 80, thus a connection DN 100 is necessary.
The steam connection flange can be dimensioned freely. In addition we adapt the overall length individually to the existing connecting piece length. Also these injectors function after the Venturi Principle, whereby steam is led also here by an annular gap and sucks in the liquid from the vessel. The liquid will be accelerated and intensively with steam mixed within the injectors conical outlet, so that a fast and noiseless condensation of steam takes place. Also we manufacture these injectors in stainless high-grade steels.
Steam Injectors after Customer's Request
The represented steam injector was made particularly after customer's request and exchanged against existing equipment. Contrary to the injectors made so far here the steam connecting piece is not tangential, but centrically arranged. Also here a very noiseless steam feed could be obtained. By the given dimensions of the previous product a movement of the interior set was necessary to the equipment center. The equipment could be inserted without change of the piping guidance, whereby extra costs were saved. The advantages in principle of our steam injectors could be maintained here. These are the large range of control of the steam quantity, the arbitrary installation position, the as far as possible cavitation-free condensation procedure, as well as the high service life by the use of stainless high-grade steels.
