Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a steam or high temperature water boiler using catalytic combustion of gaseous or liquid hydrocarbons.

Complete combustion of hydrocarbons at relatively low temperatures, i.e., around 120 to 400 degrees Celsius, without emitting toxic substances and without flames, flames, or smoke is essential for the chemical phenomenon called "catalytic oxidation." It is well known that this is a characteristic.

Catalytic oxidation is therefore a clean method of heat generation that does not require chimneys or flame tubes of any kind, and is generally a method of energy generation.

Catalytic oxidation is a particularly economical method of heat generation with an efficiency close to 100% since no heat is wasted, and the cost of hydrocarbons per IJ with this heat generation method is lower than that of all other heating devices. It turns out that the reduction in price is around 25-30% and even 35%.

The object of this invention is to provide a boiler that uses catalytic oxidation of hydrocarbons to generate pressure steam or hot water with energy or heat that can be collected in different ways depending on the intended purpose.

According to the invention, the steam or hot water boiler has at least one catalytic element which, when brought into contact with the hydrocarbon in the presence of air, causes catalytic oxidation of the hydrocarbon to a temperature of 400°C. An exothermic reaction can be produced with a maximum temperature of the order of 200 ft and is used to evaporate or heat a liquid flowing in a closed or open circuit.

This liquid can be water or other suitable liquid.

Preferably, this boiler has several catalytic elements arranged vertically in the form of accumulators inside the casing, and the spaces between these catalytic elements are filled with liquid by means of rows of tubes, and the liquid is passed through these tubes. The fuel is delivered to the catalytic elements by main pipes that connect the tubes to each other and serve as many rows of diffusers as there are catalytic elements so that the liquid flows and forms a wall-like screen without intervening gaps between the catalytic elements. supply.

The catalytic element, which can preferably be based on platinum sponge, cobalt sponge or ferronickel sponge, is energized by an electrical resistor or a spark device, among which is an aeration device, an electronic device, a piezoelectric device, etc. generates sparks.

In a special type of configuration, the combustible hydrocarbon is a compressed gas, such as butane or propane, and the supply of gas to the catalytic element is performed from the gas source after the gas has flowed through a suitable pressure regulator. .

According to another possible type of configuration, the combustible hydrocarbon is a liquid under normal conditions, and the supply of liquid to the catalytic element takes place by capillary action, injection action or atomization action.

The vapor generated and collected above the catalytic element can flow through a circuit that can be varied according to the intended purpose.

In one type of configuration, the generated steam is supplied to at least one receiving device, such as a steam engine or steam turbine, with a steam passageway at the bottom of the catalytic element and a condenser for the steam and a heat sink for cooling. a closed circuit created by a thermally insulated pipe system for conducting the vapor to the receiving device, and a pipe system for the return of the vapor, for the liquid containing the vessel, for the vapor above the catalytic element; It is a road.

At least one cylinder is constructed in such a way that the receiving device communicates with a thermally insulated steam supply pipe and a steam return pipe through two opposite inlets and two opposite outlets which are alternately opened and closed, for example by a distribution device. A closed-circuit steam engine in which the steam acts in each cylinder alternately on one force on the surface of the piston and on the other, combined with a device by which the piston transmits and converts motion. It has a piston rod.

The boiler of the invention in combination with such an engine forms a system that operates with high efficiency, pollution-free and quiet, and therefore has significant advantages when compared to conventional engines.

double-acting piston, suitable thermal insulation,” and high steam pressure (
The best diesel engine has a pressure of almost 15 ky.
/criL, but in this invention the pressure is 25
ky/crA and 50 y/d); higher efficiency is obtained.

In another type of arrangement of the invention, either the steam generated or the hot water is fed to at least one heat exchanger.

Depending on the type of heat exchanger or heat exchangers, they may be used for different purposes, namely: (a) housing with radiators, outlets for hot air, or suitable devices for distributing and diffusing the heat generated; or for use in closed circuit central heating for industrial buildings; (b) for use in water heating installations, whether domestic or industrial; and (c) for use in combination with central heating and water heating. , the boiler can be adapted.

Furthermore, the boiler of the invention is provided with a certain number of additional devices for regulation and safety, such as pumps, valves, pressure stabilizers, thermocouples, atmosphere monitoring devices, bypass pipes, etc., which will be described later. be able to.

The invention will be better understood from the accompanying drawings and the following description thereof, which illustrate by way of non-limiting example several types of boiler configurations corresponding to a variety of possible applications.

An arrangement of the type shown in FIG. 1 is particularly suited to the engines shown in FIGS. 2-4.

Generally, the steam generator or boiler contains a catalytic element that produces an exothermic reaction by catalytic oxidation when it comes into contact with a hydrocarbon-based fuel, either liquid or gaseous, which exothermic reaction produces pressurized steam acting on the pistons of the engine. supply.

The engine shown side-mounted has two cylinder blocks 1 opposite each other.

Obviously, their dimensions vary according to the desired power, but they are always relatively small.

Each cylinder block 1 has a removable sleeve 2,
2d is provided.

Sleeve 2 creates a chamber for cylinder 3, and two sleeves 2
Each of a creates a distribution chamber 4, 5, respectively, on the side of the cylinder 3.

The distribution chamber 4 is connected to the cylinder 3 through two inlets 5a, 5b for pressurized steam near the ends of the cylinder 3 and the distribution chamber 4.
It will be communicated to.

The distribution chamber 5 communicates with the cylinder 3 through two steam outlet lowers a and 7b.

γb is near both ends of the cylinder 3 and distribution chamber 5.

A tube 8 coming from the inside and outside 9 extends into the distribution chamber 4.

Another pipe 10 connects the distribution chamber 5 to the boiler 9.

The introduction of steam takes place through pipe 8 and the discharge of steam takes place through pipe 10.

A piston 12 fixed to a rod 13 in the chamber of each cylinder 3
to accommodate.

An oil conduit 14 passing through the rod 13 leads into the piston 12 and ensures lubrication of the top of the cylinder 3.

The sleeve 2 has an intermediate spacer wall 15 through which the rod 13 passes.

The end of this rod 13 outside the chamber of the cylinder 3 is fixed to an auxiliary piston 16 which fits into the outer part 17 of the sleeve 2 with a sliding fit.

The seal of stick 13 is Pacific (paci-fi).
c) type self-lubricating packing ring 18, the sealing effect of which increases with the pressure applied in the chamber of the cylinder 3.

The packing rings 18 are themselves held in position by rings 19.

A slide valve 20 fixed to a rod 22 is housed in each distribution chamber 4,5.

Each slide valve 20 has a cylindrical shape, and its ends have two heads 20a provided with sealing rings.

20b is formed.

When one of the heads 20a, 20b covers the inlet 6a, inlet 6b, outlet lower a, or outlet lower b of the distribution chamber, the head 2 is placed at a distance such that the other of the heads does not cover it.
0a.

20b to each other.

The rod 22 exits the chamber through an intermediate wall 23 in the sleeve 2a.

Self-lubricating packing ring 2 that fits against the intermediate wall 23
4 ensures a seal around the rod 22.

These packing rings 24 are of the same type as the packing rings 18 described above for the chamber of the cylinder 3.

The cylinder block 1 and the inlet pipes 8 and outlet walls 10 for steam are thermally insulated by suitable thermal insulators 27.

A crankcase 28 is placed between two cylinder blocks 1, and a power shaft 29 passes through the crankcase 28.

Transmission of the movement of the piston 12 to the power shaft 29 is effected, as in conventional engines, by a connecting rod 30, which is rotatably connected to the auxiliary piston 16.

These connecting rods 30 are attached to a crankshaft (not shown) provided in the power shaft 29.

Alternating motion of the slide valve 20 can be obtained by the camshaft 32 rotating in synchronization with the power shaft 29.

For this purpose, each rod 22 fixed to the slide valve 20 is rotatably connected to a push rod 33, which is held against a cam 34 by a compression spring 35;
Insert it into the hole of stick 22.

The arrangement described above and illustrated in FIGS. 2-4 is only one special type of arrangement.

The cylindrical slide valve 20 can then be replaced by a different type of slide valve, such as a poppet valve, or other reciprocating or rotary dispensing device that performs the same role.

The conventional mechanical transmission can be replaced by a hydraulic transmission, the auxiliary piston 16 then becoming a compressor for the oil.

Similarly, there is no limit to the number of cylinder blocks 1, since the engine can be made with a single cylinder as well as with multiple cylinders.

A boiler 9 generating steam at the required pressure for supplying the cylinder 3 is housed in a casing, which is thermally insulated by a suitable thermal insulator 36, the dimensions of which depend on the desired power.

Catalyst elements 37 fixed to vertical supports 38 are arranged as a set of devices in the casing.

These catalytic elements based on platinum sponge, cobalt sponge or ferronickel sponge have very long lifetimes of the order of 10 years.

Fuel supply is provided through tubing 39 serving a series of diffusers 40 , each diffuser 40 serving a catalytic element 37 .

A vertical tube 42 is placed between the catalyst elements 37, each ending at each end of the catalyst element 37 in a reservoir 43,44.

Being at the bottom of the casing, 43 serves all the pipes 42, and being at the top of the casing, 44 serves two chambers 44a, 44b which communicate with each other through one or more connecting pipes. Become.

The steam circuit is a closed circuit outside the casing between reservoirs 43,44.

The heat insulated inflow pipe 8 mentioned above is 44 because it is above.
exit and end in distribution room 4.

The already mentioned outflow pipe 10 leaves the distribution chamber 5 and ends in a condenser 45, which is located at the top of a cooling radiator 46, the bottom of which passes through a pipe 47 for the bottom 4
It connects to 3.

The air inlet pipe 48 is located on the side of the casing and is provided with a filter 49 and an adjustable butterfly valve 50 to suppress dirt particles.

A tube 48 that contacts the fuel introduced through the diffuser 40
In the presence of air introduced through the catalytic element 37, the catalytic element 37 is a site of considerable heat dissipation, and the temperature of the catalytic element is about 40°C.
The temperature is 0 to 450°C.

The liquid collected in 43 for the bottom is thus evaporated in tube 42 and a pressure varying between 25 ky/ffl and 50 y/crt is obtained in 44 for the top.

The evaporation tubes 42 disposed between the catalyst elements 37 are joined together by vanes or other devices (not shown) so as to form a wall-like screen between the catalyst elements 37 without intervening gaps. , such screens mutually block direct radiation from the catalytic elements.

The pressure steam coming into the cylinder block 1 via the inlet pipe 8 is alternately guided to the ports 6a, 6b due to the reciprocating movement of the heads 20a, 20b of the slide valve 20.

The steam thus introduced into the cylinder 3 passes alternately between one side and the other of the piston 12 before it escapes and is consumed passing its pressure through the output lowers a, 7b and the outlet pipe 10. to work.

Steam action is simultaneously applied to the inner surface of one piston 12 and the outer surface of the other piston 12.

The cycle concludes with cooling action in condenser 45 and radiator 46 and final expansion of the steam.

Note that the piston 12 is permanently powered and has no rest time.

If required, a portion of the steam generated by the boiler 9 can be subjected to a different cycle, for example for operating a turbine.

Various auxiliary components allow the device to operate under optimal conditions.

A pulsating pump 52 driven by the power shaft 29 ensures the supply of fuel through the line 39.

Here the fuel is liquid, but in versions of this engine compressed gases such as butane or propane can be used.

The system is controlled by a butterfly valve 50 for air inflow and a valve 51 in the line 39, which is provided with a manual actuator which serves the same purpose as the accelerator of a conventional engine.

A variable-port valve 53 in the inlet pipe 8 provides an additional possibility of control by acting directly on the amount and pressure of the steam introduced.

The cooling action is accelerated by a tube 54 which picks up liquid drawn from the bottom of the radiator 46 by a pump 55 which is driven by the power shaft 29.

Bypass pipe 57 connects inflow pipe 8 directly to condenser 45 .

The bypass pipe 57 is provided with a butterfly valve 58, which is controlled by a graduated spring, the butterfly 58 forming a safety device in case of overpressure.

The catalytic element 37 is energized by an electrical resistor 59 which is manually switched on at startup but automatically shuts down and restarts when necessary.

Finally, a constant supply of water or other liquid selected to receive the calorific radiation of the catalytic element 37 is preferably taken up from the bottom of the radiator 46 via a pulsating pump 60, which
7 and is operated by the steam and pressure requirements of the engine.

Although rapid, the rise in temperature and pressure requires a certain amount of time.

A device for immediate starting can therefore be combined with the engine.

For example, 10 kg during the operation of a steam engine to assist
/crA of compressed air.

A tube connects this auxiliary to the cylinder block 1, so that the expansion of the compressed air causes the engine to operate in the same manner as steam.

As soon as steam is available, this tube is automatically removed from the circuit.

Figures 5 and 6 illustrate two other types of configurations of this steam waste generator.

Similar to the configuration of the type described above, the catalyst elements 37 are arranged inside the casing in groups of two, one front-to-front and the other back-to-back as a unit. The casing is then thermally insulated by a suitable thermal insulator 36.

The number of catalytic elements 37 depends on the number of radiators or hot air outlets to be served, or on the desired output of hot water, or on the combination of these two as may occur in practice. Depends on requirements.

The catalytic elements 3 are connected by tubes 39 serving as many diffusers 40 and starting devices 61 as there are catalytic elements 37 in the boiler 9.
Supply fuel to 7.

With reference to FIG. 5, this fueling from a gas source 62 to the catalyst element 37 occurs after flowing the gas through a suitable pressure regulator 63, such as with propane or butane gas.

Referring to FIG. 6, when supplying liquid fuel to the boiler, the supply of liquid fuel to the catalyst element 37 is preferably carried out by capillary action, either by injection or by atomization.

The fuel contained in the tank 64 is caused to flow by gravity or by the pulsating flow pump 52. In the case of gravity, the tank 64 is arranged so as to give a water head as shown by the chain line in FIG. 52 is driven by an electric motor or by an auxiliary steam turbine 65.

A manually operated butterfly valve 51 allows fuel to reach the tubing 39 and the diffuser 40.

The ignition of the catalytic elements 37 is effected simultaneously at the bottom of each catalytic element by means of a single contact actuating the device 66, and the spark within the device 66 is driven by a battery, other power source, electronic device, or piezoelectric type self-ignition method. It is caused by something.

The pressure stabilizer 67 automatically controls the amount of gaseous or liquid fuel introduced into the diffusion device 40 of the catalyst element 37 and the re-ignition of the catalyst device 3γ by the device 66 when necessary. pipe system 3 through a small diameter pipe from one
A pressure stabilizer 67 is connected to 9.

This pressure stabilizer 67 can be used as an outlet for hot air, which in the case of a steam circulation system closed for this purpose, is served by a radiator 68 (FIG. 5) by a pipe 69 (FIG. 6) from a blower 70. preset according to the heat dispersion requirements of or when using the boiler only to heat water or to combine central heating and water heating.

As will be clear in the following case, the boiler acts as a closed circuit and the tube 71 shown in dashed lines in FIG.
The pressure stabilizer 67 that connects this pipe to the general water supply circuit can be replaced by a thermocouple.

In the pipe system 39 for introducing the fuel, inside the casing, an atmosphere monitoring device 72 is arranged for safety reasons and in accordance with good regulation, so that the fuel can be detected from defects during operation of the boiler or inside the casing. Shut off by chance due to a change in the atmosphere (leakage of gas or other fuel).

Of course, if an accident occurs at the fuel source, the same monitoring device can take control.

When a number of tubes 42 are placed between the catalytic elements which directly receive the radiant heat of the catalytic elements 37, and the circulation of water as a suitable liquid is a matter of boilers working in closed circuits only for central heating, Water or a suitable liquid is circulated in the tube 42, or water is added from the outside in the case of water heating alone or water heating in combination with central heating, and as will be seen, one of these two effects can be achieved. or the other can be stopped at any moment simply by actuating a cock installed in the corresponding circuit for this purpose.

Tube 42 can be made of steel, duralumin, cast steel, or other metals or alloys.

The tubes 42 are joined together by vanes or other devices to form a wall-like screen between the catalytic elements 37 without intervening gas, so that direct radiation from one catalytic element to another is possible. prevent.

The cross-section of the catalytic element varies according to the temperature and output to suit the demand.

The top of the pipe 42 is connected to the steam chambers 44a, 44b, which communicate with each other via one or more connecting pipes 73 and through a check valve 75 to the distribution pipe 7.
It connects to 4.

In the heating device with a radiator shown in FIG.
the number of radiators 68 that communicate with the steam condensing vessel 76 and are intended to serve, and/or the desired hot water temperature and output when acting as a water heater with or without a heating device. The amount determines the capacity of the steam condensing vessel 76.

In the pulsating air heating device shown in FIG. 6, either steam or hot water is supplied through a tube 74 to a tubular or honeycomb radiator γ7.

Blower 70 emits an air stream through radiator 77 and collects this air by tube 69 so that it can be directed toward an outlet for hot air distribution.

A pump of the same type as pulsating pump 52 can be provided in one of the tubes 74 between the steam chambers 44a, 44b and the steam condensing vessel 76, this pump serving as a circulation device.

The rows of tubes 42 are connected at their bottoms to the main tube 47 and, in the case of a steam generator or boiler operating in a closed circuit, the water is transferred into a radiator 68 (FIG. 5) or for pulsating air. A tubular or honeycomb radiator 77 (sixth
After water has been used in the main pipe 47 (FIG.), water is supplied to the main pipe 47 from a reservoir 78, and all water return pipes 79 communicate into the reservoir 78.

When working with hot water without generating steam, the water supply to the main pipe 47 and the radiator, including the radiator of the pulsating air system, is circulated into the circuit according to the demand and the requirements of the circuit. The same can be obtained by installing the device.

When working with steam, the water return pipe 79 terminates in a receptacle 80, and the receptacle serves as a communication vessel to the most desired level in the pipe 42 for optimum efficiency of the boiler. 7 to a certain level corresponding to the simple principle of
8 is always maintained by the float 81.

The role of the float is therefore to regulate the introduction of water from vessel 80 to reservoir 78.

In the case of a pulsating flow pump 52 driven by a steam turbine 65 (shown in FIG. 6), the steam turbine 65 includes a tube 42.
Steam is supplied through a small diameter pipe 82 from a steam chamber 44a at the top of the row.

Steam return occurs through pipe 83.

In this case, for a short period of time, at most 20 to 25 seconds, prior to the first generation of steam by the catalytic element in order to activate the steam turbine 65, the steam turbine is started by means of a clock timer or from an accumulator or power line. This is done by means of a small electric motor acting on the clock, and in either case, when the steam begins to operate the steam turbine, a shutoff device acting on the steam automatically removes either the clock timer or the electric motor from the circuit.

As is obvious, and as has already been made clear from the foregoing, the invention is not limited to this type of boiler configuration by way of a non-limiting example.
