Description

Isolation block

The innovation relates to an insulating varnish for closure doors, in particular for heating boilers

Generic term for the protection claim.

Such insulation blocks are generally known and in use, although there is a tendency, the refractories used hitherto. "Moldings by im To replace vacuum pullable ceramic fiber farm parts, which, with otherwise identical or better properties, are often lighter than previously veneered refractory molded parts on, for example. Al-Fe-Mn-Si base.

The noise insulation function of such Iaolationsblocks is Particularly important at the locking doors of heating pots, where the burner flame is deflected in the pot-like combustion chamber and the hot gases flow towards the boiler, uio them in the area of a Reach the deflection chamber in the hot gas flues. In modern boilers of this type, the heating gas flue is Ring-shaped in cross-section, subdivided into individual trains by ribs and surrounds the combustion chamber.

A certain problem here is the pending uniform loading of the individual trains, in which there is of course the tendency that the trains from bottom to top act to a greater extent, beers. More or less complex measures one to counteract such distribution have so far been made either in or on the heating gas flues themselves ^ 3Tden or in or on the adjoining smoke gas containment chamber, which on the one hand represents additional elements to be manufactured and installed and on the other hand an obstruction to the cleaning process when the trains need to be cleaned.

The innovation is based on the task of taking the necessary measures for better heating gas distribution to simplify the moves and to meet them on an element that has to be planned anyway and that, because sitting on the locking door, automatically frees access to the heating gas flues when the The door is opened.

This task is the input with an insulating block named type after the innovation by what is covered in the identifier of the protection claim.

novel insulation block is arranged on the locking door in such a way that the cross-section The thicker or thicker part seen is in the upper half of the locking door.

This novel R ε to shape and arrangement does the Cross-section of the deflection chamber correspondingly reduced and thus the inflow resistance increased, iuas overall to a better distribution of the heating gas fees leads.

This new spatial shape of the insulation block can of course be realized with all refractory materials, including ceramic fiber material, with which is the removal of the insulation block using the vacuum suction process he follows.

The novel insulation body is based on the following the graphic representation of exemplary embodiments in more detail srlMutert.

It shows

1-3 show sections through different embodiments of insulation blocks;

Fig. K shows a particular embodiment in view

and
5 shows a section through the embodiment

according to Fig. k along line V-V in Fig. h.

Regardless of the different shapes, the farm body is of refractory material denoted by 1 throughout FIGS. 1-5. Preferably be this from a ceramic fiber pulp in a vacuum suction process using a suitable sieve shape manufactured. The respective burner-side deflection chamber 4 with the heating gas flues is indicated by dashed lines, in which the flame bzu. Heating gases flow in from the deflection chamber, whereby due to the? Temperatures a preferred flow to those running in the upper half of the respective heating boiler Heating gas flues results, but this is counteracted by appropriate shaping of the insulation block shall be.

This tendency is counteracted by appropriate design or arrangement of the acted upon surface 2 counteracted.

Be the embodiment of FIG. 1 is for this entire surface 2 is slightly inclined, in the case of Fig. 2 only the upper half and in the case of Fig. a gradation of 2 'is provided.

Since this results in correspondingly reduced cross-sections in the upper half of the deflection chamber k , the resistance is already in front of the heating gas flues 5

increased, so that thereby the heating or flue gases in strength The heating gas flues below also flow to a larger extent, as the deflection chamber has larger inflow. Overflow cross-sections offers.

In this sense, however, it is also possible to form the Isolatiansblackes according to FIG. 4, 5, in which only the located in axial projection in front of the HeizgaszQgen Areas of the insulation block or molded body 1 accordingly are trained.

Referring to FIG. U, 5 Btellt this embodiment is in the form of a circle ring 2 ', whose surface is acted upon total inclined in the sense of Fig. 1, or in the form of a circular ring section 2''* with correspondingly inclined AnstrBmflSche 5.

With 6 is the central opening for access

or flame tube
of the burner / marked on the outside of the lock door

This problem-free and simple design of the insulation block or molded body 1 makes largely different, the The aforementioned adverse flow tendency counteracting measures on the heating gas flues or in the rear Flue gas collection chamber and exhaust chamber can be dispensed with, which are basically always more complex.
