Definitions
- EP 0 524 736 A2 discloses a method and a device for carrying out a controlled reaction in a porous matrix.
- gas or steam is conducted from a space m of tubular porous means extending vertically upward therefrom.
- the combustion takes place within the porous medium.
- the heat generated during combustion flows predominantly downstream and enters another room. -
- This method is not suitable for burning liquid fuels.
- the position of the flame front in the porous body is unstable.
- a device for regulating the volume flow coupled to a temperature measuring device is required for position stabilization.
- the heat generated in the known method is incompletely transferred to the surrounding medium by convection. Preheating of the combustion mixture, which increases the efficiency, does not take place. Gas or steam residues remaining in the room after switching off can disadvantageously contribute to spontaneous combustion.
- the known evaporator is disadvantageous in several ways. Because the mixture with air only takes place after the oil has evaporated, a large distance is required to form a homogeneous air / oil mixture. Because of the suction of the oil into the porous plate based on capillary forces, the porous plate must be of very fine pores. However, this means that it is clogged by impurities contained in the oil and must therefore be cleaned regularly. In order to provide a sufficient amount of oil vapor, the porous plate must have a relatively large area that is in full contact with an oil supply. This requirement counteracts a compact design of the known oil burner. Except- This means that it is not possible to start up a burner that has been combined with this evaporator because the formation of the oil vapor takes some time. After the burner has been switched off, an oil vapor / air mixture remains in the evaporator, which can lead to undesired combustion.
- the liquid fuel is distributed by means of a distribution device and transferred to a downstream reactor with a porous agent having a communicating pore space, the Peclet number of which permits flame development within the porous agent.
- the method according to the invention enables a particularly efficient and low-pollution combustion of the liquid fuel used.
- a gaseous oxidizing agent in particular air, is fed to the distribution device and / or the porous agent to form a mixture consisting of the liquid fuel and the oxidizing agent.
- the distribution device can have a device for atomizing the liquid fuel.
- the device for atomization can, for example, be washed around by a stream of gaseous oxidizing agent.
- the atomization device advantageously has a Nozzle that is supplied with liquid fuel under pressure.
- the atomization device can also have a 2-substance nozzle, the liquid fuel and pressurized oxidizing agent are supplied. - This forms a first mixture consisting of oxidizing agent and liquid fuel, which can be enriched with additional oxidizing agent.
- the atomizing device is expediently arranged in the vicinity of the porous agent. It can be moved back and forth in relation to the porous medium. If the porous means is cylindrical, the atomizing device is advantageously arranged in the cylinder axis.
- the reactor has a housing which accommodates the porous agent, the housing being able to surround the porous element and the device for evaporation.
- the porous medium is expediently surrounded by a heat exchanger.
- the porous medium is arranged below the distribution device, so that a counterflow which is produced during combustion and is directed counter to the mass flow is formed. This enables the mixture supplied by the mass flow to be preheated. In addition, the counterflow slows down the mass flow. This keeps the position of the flame front stable.
- FIG. 4 shows a schematic cross section through a third exemplary embodiment of a device according to the invention
- the porous medium 6 extends over an essential section of the housing 14.
- a mixture inlet side 15 of the porous medium 6 is here directly supplied with liquid fuel emerging from the liquid fuel nozzle 11.
- the mixing, homogenization and evaporation of the mixture takes place in the vicinity of the inlet side 15 of the porous body.
- the mass flow is directed vertically downward.
- the combustion creates a counterflow, which is directed vertically upwards.
- the counterflow slows down the mass flow. As a result, the position of the flame front in the porous medium is kept stable.
- the 2-substance nozzle 17 consists of a liquid fuel nozzle 11 which is surrounded by an air nozzle 18.
- the air nozzle 18 is provided with openings 19 for sucking in air.
- the air / liquid fuel mixture exits through an opening 20 provided in the air nozzle 18.
- FIG. 6a shows a cross section through a distributor 2.
- This essentially consists of a cylinder 21, the interior of which is connected to the environment via radially arranged nozzles 22 Connection is established.
- the arrangement of the nozzles 22 is particularly clear from Fig. 6b.
