Definitions
- a boiler constructed using a composite material.
- the invention relates to a polymeric matrix composite material boiler for use, in particular, in a water heater.
- a first drawback of the metal boilers traditionally used in water heaters is constituted by the phenomenon of electrolytic corrosion which occurs on the internal surfaces of the said boilers.
- protective systems are adopted, such as the application of suitable internal claddings or special sacrifical or impressed current anodes.
- a further drawback of the traditional metal boilers is the negative environmental effects caused during the production phase by the use of chemical substances to prepare the metal surfaces.
- a still further drawback is constituted by the short working life of the traditional metal boilers.
- the designs proposed until now for the manufacture of synthetic material boilers for water heaters have tended, in general, to prefer materials with particular mechanical features and particular forms of structural strengthening.
- the international patent application PCT/IT97/00186 examines the use of alloy polymeric materials modified with other technical polymers since the said materials have positive mechanical stress resistance features, which are due also to the addition of reinforcing agents.
- the international patent application PCT/EP98/07982 proposes a way of reaching the considerable mechanical resistance features of a boiler for water heaters made of a synthetic material with structural reinforcing ribs. In both inventions indicated the boiler used is manufactured by means of the joining together of two or more components by welding or using adhesives.
- a first aim of this invention is to make it possible to manufacture a boiler made of a synthetic polymeric material as a single body without a structurally weak design.
- a second aim of the boiler in question in this invention is that the production costs shall be similar to those of a boiler with an identical capacity but made of metal. Further aims are constituted by the ease with which the components can be recycled and a guaranteed working life of at least ten years. Furthermore, the said aims are achieved with the least impact on the environment possible during the production phase and with the energy consumption, both during the production phase and when the water heater fitted with the boiler is in use, being extremely low in comparison with the other water heaters available on the market.
- the boiler in question in the present invention for use, in particular, in a water heater, fitted with a heating element and which is preferably, but not exclusively, electric and of the kind made entirely of a polymeric matrix composite material, is characterised by the fact that it is constituted of the two following layers, positioned one after the other in order from the inside to the outside of the said boiler:
- thermoplastic or elastomeric matrix material a first layer of thermoplastic or elastomeric matrix material, the said layer being manufactured as a single body and the said layer having characteristics which make it suitable for contact with water;
- a second layer composed of a plurality of filaments or synthetic strips wrapped around the first layer, the said filaments or strips being covered with resins which agglomerate by reticulation or fusion; the said second layer being manufactured as a single body and designed to create a structural resistance for the boiler; the said first and second layers being detachable from each other only after the said boiler has been destroyed, the said destruction being such as to allow the said boiler to be recycled at the end of its working life.
- Figures 1 shows a boiler fitted into an electric water heater
- Figure 2 shows, schematically and out of scale, a section of the boiler
- the number 1 is used to denote a water heater in which a boiler 2 is fitted.
- a heating element 3 Inside the boiler 2 is a heating element 3, of an electric kind.
- the number 4 indicates a first layer which comes into direct contact with the hot water or the water to be heated and the number 5 denotes a second layer which is outside the first.
- the first layer 4 is made of a thermoplastic matrix material constituted of polyolefinic, homopolymeric, copolymeric, metalocenic resins or PET- based resins, or PPE/PPO-based resins or even, a mixture of other compatible polymeric materials or those which have been made compatible, either semi-crystalline ones or amorphous ones.
- the first layer 4 can also be made of an elastomeric matrix material constituted of PB or PLB-based resins or even a mixture with other compatible polymers or those which have been made compatible, either semi-crystalline ones or amorphous ones.
- the two layers 4 and 5 both being in a single body, are completely detachable from each other.
- One layer 6 of the water heater 1 containing the boiler 2 is wrapped around the outside of the said boiler and is designed to provide thermal insulation for the said boiler; the layer 6 being detachable from the external surface of the second layer 5.
- a first advantage of the boiler in question in the present invention is that the second layer, designed to supply the necessary structural resistance for the said boiler, guarantees, at the least, a bursting value, when hot, of no less than 30 bar at 70°C and a number of mechanical fatigue cycles, from 1 to 8 bar, of more than the 20,000 required by the specific safety standards.
- a second advantage is constituted by the fact that the industrial cost of the boiler object of the present invention is substantially identical to that of a boiler with the same capacity but made entirely of metal.
- a further advantage is constituted by the ease with which the single components when ground up or the entire boiler unit in question in this invention can be recycled.
- a still further advantage is constituted by the low impact on the environment during the production phase and the energy consumption during both the production phase and when the said boiler is in use, which is extremely low in comparison to that of other products available on the market today.
- the boiler object of the present invention has the further advantage that its heat production levels, as well as its mechanical performance levels, are no lower than those of the metal boilers.
- a further embodiment envisages the application of a layer composed of a plurality of filaments or strips of synthetic material covered with resins which agglomerate by means of reticulation or fusion outside the said polymeric material boiler, for use, in particular, in a water heater, fitted with a heating element and which is preferably, but not exclusively, electric and characterised by the fact that it is assembled from two or more elements fitted together by welding , adhesive, or another method.
- the said covering is applied to the said composing elements when fully assembled.
