Description

b /
The present invention relates to hot water generators of the "multi-energy" type allowing two modes of energy use to be exploited, namely
a fossil fuel combustion mode: fuel or gas
an electric heating mode.

cl
Known devices of this kind combine in parallel or and in series two separate heat generators. Such installation.

become heavy and expensive as soon as the powers engaged.

exceed a few tens of KW.

d /
The "dual-energy" boiler according to the invention makes it possible to avoid these drawbacks.

 It integrates into a common structure (monobloc) a hearth and its heat exchanger with smoke tubes with a battery of electric heating resistances directly immersed in the water reserve as well as an electric control panel.

The device according to the invention makes it possible to program
- the generator's operating time and time for energy:
fossil
- the generator's operating time and time for energy:
electric.

- the electric call power according to the availability of the
sector and within the limit of the maximum electrical power of the
generator.

 These three actions make it possible to rationalize and adapt energy consumption to the different supply tariffs, as well as to the requirements of the electrical networks.

 The flexibility and safety of use of such a device can contribute to optimizing energy savings.

The two attached drawings are: Fig.l, front view cut from the right side and Fig.2, profile of the striated round iron. f,
As shown, the device comprises a heating body 1 enveloping a combustion chamber 2, a gas reversal bowl 3 an exchanger tube bundle 4 and a batt of heating elements 5
The submerged gas reversal boot 3 provides an excellent exchanger tramp which reduces the thermal stresses borne by the rear tube plate.

 The refractory shutter 6 is set back from the bottom of the reversing boot 3 this arrangement reduces the surface temperature of the refractory as well as its radiation on the tube plate.

 In each of the bundle tubes, a doubly striated round iron is placed.

1st streak: a propeller over its entire length (swirl effect
nary)
2nd streak: a short helical streak (vibratory effect)
of the vortex).

 The heating elements or immersion heaters 5 are arranged in the lower part of the heating body which ensures at this level the homogeneity of the heat exchange by reducing any degassing effect.

 The front and rear faces in thick thick sheet metal serve as support for a covering in removable sheets separated from the heat-insulating material 7 with high insulating power and creating an air layer reducing as much as possible the losses of heat-resistant material.

 The electrical panel 8 brings together the wiring for the distribution of electrical power as well as the regulation and programming commands for two energies.

gi
The device which is the subject of the invention can be used in all cases of hot water production: heating, sanitary water in a power range ranging from 50 KW to 1500 KW. Example heating of buildings, offices, industrial premises of schools, hospitals and generally in areas where the rational and economical use of production.

electric remains favorable.
