Definitions
- the invention relates to peripheral and heat-stressed connection and / or closure elements for boilers according to the preamble of claim 1.
- connection and / or closure elements for boilers were, in particular, straight and / or curved flue gas pipes, flue gas collecting boxes, rear combustion chamber boundary walls and finally also any type of closure covers and closure doors, as are required on boilers depending on the design.
- the most varied and more or less optimal insulation methods and designs are well known for the thermal insulation of boilers themselves. So far, more or less, the actual exhaust area of boilers has been neglected, ie in particular the exhaust pipes leading to the chimney, which as a rule remained uninsulated due to the relatively high installation effort for attaching insulation mats or the like.
- flue gas plenum chambers are provided on such boilers on the flue gas exhaust pipe, they were insulated (see US-A-4 320 869), but because of their peripheral assignment to the boiler, it was always difficult and associated with additional effort, such flue gas flue boxes, Regardless of whether they were located in the rear wall or in the front wall area depending on the boiler design, isolate them or include them in the overall boiler insulation. The same applies to any type of boiler opening lock.
- the invention is therefore based on the object to provide insulation for peripheral and heat-stressed connection and / or closure elements of boilers, with which the manufacturer of such elements and also the boiler manufacturer, which usually supplies such elements, should be able to do so to be able to produce such insulation from the outset in the simplest way, so that it is not necessary from the outset to add insulation or, as far as flue gas collection boxes and closure elements on the boiler are concerned, their insulation can be simplified, with the proviso that at the same time for one to provide good sealing options.
- This solution according to the invention is therefore not known insulation materials, such as, for example, the article according to US Pat. No. 4,320,869, such as laminated glass fiber or rock wool mats, and also not heat-resistant foamable plastics, which in heating boilers anyway are only available in non-critical ones Areas can be applied, but by an example Spraying or brushing-on mass with dispersion character and inorganic fillers, for which it is essential, in addition to thermal insulation and resistance, to be tough and firmly adhering and which is also softenable, so that it can also meet the condition that it can simultaneously act as a sealant .
- insulation materials such as, for example, the article according to US Pat. No. 4,320,869, such as laminated glass fiber or rock wool mats, and also not heat-resistant foamable plastics, which in heating boilers anyway are only available in non-critical ones Areas can be applied, but by an example Spraying or brushing-on mass with dispersion character and inorganic fillers, for which it is essential, in addition to thermal
- the entire outer surface of the element in question is provided with this layer, that is to say also the areas which are no longer exposed after installation or connection to the boiler.
- the layer in the slide-on or connection area simply pushes together, remains in the gap between the two elements to be joined, depending on the dimensional tolerances, and can then also be spread again by hand or with a suitable auxiliary tool without further expansion of the bulge formed to be smoothed. Special measures for the subsequent drying of the mass are not necessary, since this results practically by itself.
- peripheral and heat-loaded connection and / or closure elements according to the invention are explained in more detail below with reference to the drawing of exemplary embodiments.
- connection or closure elements shown do not require any further explanation in detail, since these are known and also with regard to their assignment to one another and to the boiler in question. All of the elements shown have in common that their entire outer surface 2 is coated with the layer 3 (shown in dash-dot lines), which has the same properties for all of the illustrated embodiments, ie this layer is suitable in a suitable manner, in particular by spraying Dispersion compound with mineral fillers, which has both heat and sound insulation properties, is heat-resistant and tough in itself, adheres to metallic surfaces both in the wet and dry state and is also softenable. These properties, as indicated schematically in FIG.
- the layer forming the insulation material contains the following components in the softened, ie ready for application: 12-18% water glass 45-55% H2O 20 - 30% mineral fillers 3 - 5% plastic polymers, such as VAC, acrylate or their copolymers 4-6% KOH
- a composition composed in this way has good mechanical resistance and excellent adhesion to the substrate and shows an elasticity which, for example, permits sawing of appropriately coated pipes without the coating peeling off.
- the material is easy to spray and shows an appealing spray pattern. Temperature resistance is given, and there is neither smoke nor odor nuisance when heated. Water at room temperature is expediently used for the softening in order to achieve softening times in the range from 10 to 15 min. to adhere to.
- the softened or softened material solidifies again to a solid insulating mass as before adding water.
