Side-fired heating system

The invention relates to a side-fired heating system, in particular a heating system, with v / elcher burners for multi-fuel operation and are to be serviced and operated from the side of the heating system instead of from the floor.

So far, the burners for heat exchanger heating systems and the like, in particular burners suitable for multi-fuel operation, have been such designed so that they could be inserted into the heating system directly at the bottom. This construction continued therefore through the fastest, since on the one hand the flame must be directed upwards, while on the other hand the technology this burner, which is suitable for multi-fuel operation, was not yet well developed at the time.

60981 1/0283

A typical example of the floor installation of such burners is described in US Pat. No. 2,851,093 by In these burners the central nozzle feeds the liquid fuel in a cone up into and through a cylindrical one Jacket sprayed through to keep the fuel inside a cylindrical chamber made of refractory material burns. In this construction, the air is supplied through a vent valve device and around the central Fuel nozzle routed around, and the construction is such designed that the nozzle device and the burner insert removed from the supporting cylinders straight down and can be used again. Other maintenance and adjustment work must also be carried out by the Underside of the heating system can be carried out, which is why it is necessary that the heating system is above the ground is arranged so that there is an appropriate space for the operation and maintenance of the heating system. The one described above Construction has significant advantages over the known designs, since in a small Combustion chamber as a result of a special arrangement of the nozzles opposite a specially constructed casing and refractory Combustion chamber a high combustion output is achieved. Additional gas nozzles are also on the underside of the known heating system installed and equipped with a separate ventilation device.

The hot environment, the dripping oil and the like do about it In addition, the maintenance is very inconvenient and difficult, and the risk of injury to the worker is considerable.

Due to the wishes of the buyer of these systems and the increasing security requirements

60981 1/0283

the need for a burner and a burner system, which works with the same efficiency as the previously known burner, but essentially does not require that the burners must be serviced and operated from underneath the heating system. These requirements require a special design and arrangement of the casing, the one lined with the refractory material Combustion chamber and the nozzle device.

The heating system according to the invention is characterized by a housing with a bottom which is enclosed by outer walls which have a flue at their upper end and are lined on their inner surface with a refractory wall, by at least one burner for liquid fuel, which is arranged in an opening located next to the outer wall in the housing base and extends through the Extending through the bottom into the housing, each burner having nozzle means extending horizontally extends under the floor to an area immediately below the floor opening for the fuel to Generating a flame under pressure through the opening, by means of a device which directs the flame to the inner surface the inner wall guides upwards, a ventilation slide device arranged under the flame guide device for the supply of air, through a control device arranged on the outer wall of the housing, which is connected to the ventilation slide is engaged, so that through the ventilation slide supplied air volume is adjustable, and by a device through which the nozzle device from the outer wall the housing can be removed horizontally from the heating system.

The invention therefore makes a side-fired one

609811/0283

Proposed burner for a heating system, which has the same high efficiency as the previous burner and it allows the operating parts of the burner to be removed from the floor of the heating system can be serviced and operated from the side of the heating system.

To drastically change the burner insert, the has proven to be functional, avoiding the nozzle device of the burner insert for the liquid Provide fuel with nozzle bores directed upwards like a fan instead of the previously described ones conical nozzle bores. It has been found to be useful to change the shape of the casing to the shape of the to adapt the injected fuel veil. The sheath has according to the invention in an advantageous manner a rectangular cross-section, which is attached to the fan-shaped Spray pattern is adapted to the nozzle device of the burner insert.

Because the casing is arranged vertically and the burner insert is inserted horizontally, it is necessary to align the nozzle device precisely with respect to the casing. It is therefore an adjusting device for adjusting the nozzle device in the area of the casing provided, with which the nozzle device is precisely set after the installation of the burner insert can be.

In a further advantageous embodiment of the invention is

60981 1/0283

only a single ventilation device is provided, which is arranged below the burner and both for the
Air supply to the area surrounding the nozzle device as well as to the auxiliary gas nozzles ensures, wherein the ventilation device can be operated by a remote control which
is arranged on the side of the heating system.

In this way, multiple side-fired burners can be installed in a heating system, with each burner is arranged next to a heat-radiating, fireproof wall, so that the necessary for the heating system Warm conditions are created.

In addition, the new nozzle design with the appropriately designed casing is able to burn the liquid fuel almost completely, whereby the in
In the form of oil, liquid fuel can be added with some steam to achieve smokeless combustion.

assume the position shown arranged in the shoulder 38, then the supporting covers 110 and 112 are fastened by means of the screws 114 in the position shown in FIG. The outwardly extending ends of the gas tubes 120 and 122 are then

* -i 609811/0283

connected to a gas line, not shown. Then the burner insert 74 is so far into the guide tube 70 pushed in until the nozzle body 76 of the burner tube engages in the opening 58 of the end plate 56. Afterward the oil supply connection 80 and the steam supply connection 82 of the connection body 78 is connected to oil or steam lines, not shown. The oil-steam line support 9 4 is then placed against the connector body 78 so that the oil channel 96 and the steam channel 98 corresponding to the elongated Burner tube 88 are connected. Finally, the U-shaped clamping fork 84 is pivoted over the cable carrier 94 and tightened by means of the clamping screw 86.

Then the cover 140 is removed from the ignition tube 138 and a flame is introduced through the ignition tube 138 until it engages around the nozzle body during a vapor-oil mixture is passed under pressure through the nozzle body 76 and emerges from the nozzle bores 102. The steam serves to to atomize and distribute the oil droplets in the air so that the combustion of the oil is improved. Well can the ventilation slide 144 can be adjusted by means of the rack 148 and the pinion 150 so that air can enter the nozzle body 76 and is introduced around it in order to maintain the combustion of the oil-vapor mixture emerging from the nozzle body. This air is contained in the casing support 48 around the guide tube 70 Port 72 supplied. After the oil-vapor mixture has ignited inside and above the jacket 60 can be supplied through the gas pipes 120 and 122 gas, so that the mixture this spot is ignited. It is easy to see that the air supplied through the openings 46 is also on the outside the casing 60 flows along, so that more air to maintain the combustion within the fire wall

60981 1/0283

Opening 3 4 of the wall of fire 32 is fed. The one at the mouth 34 arranged shoulders 3 8 cause a turbulence of the supplied air, so that a more complete combustion of the oil-gas mixture is achieved and thus smoke gases and the impurities contained in the exhaust gases are reduced. Fan-shaped flames 161 are then generated by the burner next to the refractory walls 26 of the heating system, so that the side walls are heated until they radiate heat to the heat exchanger tube 2 4. It is also on it pointed out that the air supplied through the space 132, the openings 46, the ventilation slide 144, the annular gap 72 reaches the nozzle body 76 and flows around it.

If it is necessary to remove or service the burner insert 74 or gas tubes 120 and 122, then it happens the removal and maintenance or the renewal in the opposite way to the installation already described. That observation sr ohr 156 is used during operation of the heating system for observation or electronic measurement of one of the Inside of the fire wall 32 used flame.

From the foregoing description it can be seen that the invention provides a side-fired burner for use in a heating system is proposed, the burner being maintained and operated essentially from the side of the heating system in contrast to heating systems, which are operated from the floor.

It is of course also conceivable that a second burner set 160 could be installed above the burners 12 (see FIG Fig. 1) in order to provide additional heating power in the heating system. With the burner 160, however, the space 132 of the vent valve housing must necessarily be on the outside of the Brenners are in the area 162.
