- the oven 3 is connected to a cyclone 4 which is intended to ensure the separation of solids from the gas stream flowing in the oven 3.
- the dried or dehydrated solids are removed periodically or continuously (according to the method) by the conduits 5 and 6.
- the drying is ensured by a hot gas stream G which circulates in the oven 3 and which is led by a pipe 7 which leaves a hot gas generator 8.

- the tubing of the exchange circuit 10 makes it possible moreover to ensure a physical separation between the heated gases and the combustion gases generated by the burner 9.
- Figures 2 to 5 show an embodiment of a hot gas generator according to the invention.
- FIG. 2 shows an external view of this generator 8. It can be seen that it comprises a substantially cylindrical tank 23. This tank will be arranged vertically (as shown in the figure) in the case of a biomass fireplace and it will be arranged horizontally in the case of a liquid or gaseous fuel burner. The lower part of the tank carries the burner or the hearth 9, the upper part carries the chimney 21 for evacuation of the combustion gases from the burner or the hearth 9. This gas supply duct 22 is also seen in this figure. fresh. This duct radially crosses the chimney 21 and (as is more particularly visible in Figures 3 to 5) it has an end which is disposed coaxially with the vessel 23 and inside the chimney 21 for discharging the combustion gases.
- FIG. 2 shows the pipe 7 which discharges the hot gases out of the generator 8.
- the internal structure of the generator 8 is more particularly visible in FIGS. 3 to 5.
- the tank 23 of the generator surrounds a number of tubings which are organized in different exchange circuits.
- the generator shown here has two concentric exchange circuits.
- Each exchange circuit is arranged in a specific chamber through which the combustion gases from the burner flow.
- the generator thus comprises a first cylindrical chamber 24 surrounding the axis of the generator and which is delimited by a first cylindrical partition 26 carried by a support 27 integral with the bottom of the tank 23 (FIG. 5).
- the generator 8 also comprises a second annular chamber 25, surrounding the first chamber 24 and which is delimited on the one hand by the first partition 26 and on the other by a second partition 28, concentric with the first partition 26.
- the second partition 28 is secured to a plate 29 which is fixed at an upper end of the tank 23 and on which is fixed a housing 30 carrying the chimney 21.
- the combustion gases C originating from the burner or the hearth 9 firstly pass through the first chamber 24 in the direction indicated by the arrows C (vertically from bottom to top, ie from the burner or fireplace 9 to the chimney 21). The gases are stopped by the upper partition plate 29 and then flow into the second chamber 25 in the reverse direction, vertically and from top to bottom.
- the flow direction of the combustion gases in the third chamber 31 is also the opposite of that which it has in the second chamber 25.
- the fresh gas is supplied to the generator at the duct 22 which is arranged coaxially with the various chambers 24, 25, 31 and inside the chimney 21 for evacuating the combustion gases.
- the fresh gas is introduced into the generator 8 in a direction D which is the opposite of that of the flow C of the combustion gases from the burner or the hearth. This opposite direction is respected in the first chamber 24. It is also respected in the second chamber 25 (as well as in the third chamber 31).
- each exchange circuit arranged in a chamber is designed to optimize heat transfer.
- Each exchange circuit thus comprises a single outlet collection channel for the hot gases and several intake channels.
- the outlet manifold and the inlet channels are connected to each other by pipes substantially parallel to each other.
- the first exchange circuit (located in the first chamber 24) therefore comprises an annular outlet manifold 34.1 which is arranged in the vicinity of the burner or the hearth 9.
- the first exchange circuit also has four intake channels 35a1, 35b1, 35c1 and 35d1 (FIG. 6). These channels are all annular except the channel 35al which is in fact a box disposed substantially at the axis of the generator.
- the diameters of the channels 35b1, 35c1 and 35d1 are also different from each other.
- outlet manifold 34.1 and the inlet channels 35a1, 35b1, 35c1 and 35d1 are connected to each other by manifolds 36 substantially parallel to each other.
- the hot gas generator according to the invention also comprises a toroidal conduit 37 for collecting the hot gases supplied by the different exchange circuits.
- the duct 37 carries the pipe 7 for discharging the hot gases generated by the generator.
- the duct 37 is connected by tubings (38.1, 38.2) to the outlet manifolds (34.1, 34.2) of the different exchange circuits.
- the manifold 34.1 of the first exchange circuit is connected to the conduit 37 by tubing 38.1 rectangular section. See in particular Figures 4 and 5.
- the second exchange circuit (that which is arranged in the second chamber 25) has a structure similar to that of the first exchange circuit.
- This second exchange circuit comprises four intake channels 35a2, 35b2, 35c2 and 35d2. These channels are all annular and disposed at the lower end of the second chamber 25.
- the fresh gas is fed from the duct 22 to the various intake ducts 35a2, 35b2, 35c2, 35d2 by tubing 33 with a rectangular section (see FIG. 3).
- Tubing 36 with a straight or corrugated profile connects the inlet channels and the outlet manifold 34.2.
- the latter is itself connected to the duct 37 for discharging hot gases by tubing 38.2 with a rectangular section. See in particular Figures 3, 5 and 6.
- the generator according to the invention therefore provides in a relatively compact volume an excellent thermal efficiency.
- a generator 8 generating a flow having a speed between 5.0 m / s and 8.0 m / s of hot gas having a temperature of about 600 0 C .
- the skilled person will easily size the generator according to the desired characteristics (temperature and flow).
- the different shapes and lengths for the pipes 36 (within the same exchange circuit and between the different exchange circuits) lead to different head losses at each tubing.
- means will be provided for regulating the speed of the hot gases leaving the various pipes.
- These means are for example constituted by valves which will be interposed between the duct 22 for supplying fresh gas and each tube which connects this duct to the various inlet channels 35 (35a1,..., 35d1... 35a2,. .., 35d2).
- a plunger 41 having a conical end 42 which is intended to cooperate with a complementary bearing surface of a support 43.
- the support 43 is screwed to a base 44.
- a spring 45 is dimensioned solely to withstand the weight of the plunger 41. last is therefore supported on its range in the rest position of the valve (as shown in Figure 7a).
- the direction of passage of the fresh gas is represented by the arrows D.
- the fresh gas from the conduit 22 enters the valve 40 through the orifice 46. It pushes the plunger 41 against the action of the spring 45. The fresh gas passes into the chamber 47 and spring downstream through the bore 48 to go to the inlet channel 35 considered.
- the gas passage section will vary as a function of the axial position of the plunger 41. An increase in the pressure of the hot gas downstream will therefore push the plunger upwards and reduce the fresh gas inlet pressure.
- the valve thus makes it possible to regulate the hot gas pressure and thus regulates the speed of the air in the various pipes.
- characteristics of the valve will of course be different.
- the different valves will be dimensioned according to the desired result, which is to obtain the same hot gas outlet velocity for all the pipes at the exhaust duct 37.
- the skilled person will easily size these different valves according to the characteristics of the generator that he realizes.
- the hot gas generator according to the invention can be implemented in different installations.
- Figure 8 thus shows a dehydration plant, for example for timber.
- This installation 1 comprises a closed enclosure 50 inside which are disposed the elements 58 of timber to be dried, placed for example on a carriage.
- the generator 8 supplies hot air through its gas evacuation pipe 7 and receives fresh air through its conduit 22.
- the pipe 7 is connected to the enclosure 50 via a pipe 52.
- the hot air After circulation in the enclosure 50, the hot air is discharged through an outlet pipe 53 which is connected to a condenser 13.
- This condenser is cooled by fresh outside air circulating in an exchange circuit and entering this circuit through the inlet manifold 14.
- the condenser 13 makes it possible to ensure the dehydration of the hot air flowing in the pipe 53.
- the air thus dehydrated is fed to the intake duct 22 of the generator 8 via the pipe 59.
- the liquid water (H20) is recovered at the bottom 16 of the condenser 13.
- An accelerator (such as a pump) 17 allows accelerate and regulate the flow of hot air G flowing in the enclosure 50 and in the generator 8.
- the duct bringing the fresh air 22 to the generator 8 is connected to a hot air recovery circuit which is extracted from the enclosure 50 receiving the materials to be dehydrated.
- Part of the hot air recovered in the condenser 13 is used to activate the burner or the hearth 9, via the duct 57.
- This duct is connected to the duct 22 by means of a three-way valve 51 whose function is to enable the extraction of a quantity of preheated air to supplement the losses possibly caused by leaks.
- Another three-way valve 54 is interposed between an upstream portion (duct 57), a downstream portion 60 (towards the burner) and an exhaust 61. It allows the regulation of the preheated air flow necessary for the activation of the burner or the home
- a mixer 55 is disposed at the inlet of the enclosure 50. It is possible at this mixer to dose the hot air from the generator 8 with a portion of the fresh air leaving the condenser 13 by means of a shutter 56.
