Description

Draft regulator for boilers of all types, especially for ship boilers. object The invention is a draft regulator, in particular for draft boilers.

The purpose of the innovation is to achieve fuel savings and to prevent the accumulation of fines in the penitentiary and in the smoke tubes, the train to regulate so that a full flow of air to the furnace is enabled and the The combustion gases are deducted as required.

Another purpose is to prevent the combustion gases, which are still warm cool on the ash pan by passing them along the front of the boiler so that this part of the boiler makes part of the warm air available that would otherwise would be lost immediately in the chimney.

Another particular advantage is that contained in the flue gases Heat that was lost for the boiler heating can be used as a draft generator in the chimney close.

As a result, the train can be in the right place at the boiler exit are regulated and thereby an effective utilization of the combustion takes place, by restricting the exhaust of the flue gases from the combustion gases can leave the boiler at too high a temperature.

The figures show an example of an embodiment of the subject matter of the invention.

Fig. I shows the boiler and regulator, seen from the front (penalty box removed).

Fig. 2 shows a cross section through the regulator.

The regulator consists of a movable two-part plate a Wrought iron, shaped like the penal box and placed on angle iron b through pin c.

The lower part of the plate is hinged to the upper part e attached so that the plate is lifted from the boiler in a horizontal position for cleaning can be.

The hinges e are connected to the lower plate by screws.

The movement device consists of a spindle screw f, the is guided in a sleeve g riveted to plate a and through a head piece h is reinforced.

The spindle screw is provided with a guide i and is through a movable union ring k and a fixed union ring 1, which with two screws screwed against each other and attached to the wall of the penitentiary box are held in their position.

To prevent the controller from being operated by unauthorized persons Provide the spindle shaft with a square m for a spanner.

The mode of action is as follows By screwing the back and forth Sleeve g is moved parallel to the plate a from and to the boiler front by slide the pin e onto the angle iron b.

To keep the plate in its correct position during operation, A locking device is attached, which consists of a screw n with a cross piece o consists, which engages around a claw attached to the upper part of the plate or leads through the same.

You can also use this innovation to increase the heating surface in the fire box and Make the smoke pipes usable by opening the air supply fully and the Trigger throttles. This results in a slower passage of the gases and a better one Combustion is achieved by the air mixing already going on in the boiler.

Claims (1)

PATEN T CLAIMS: i. Draft regulator for boilers of all kinds, especially for ship boilers, characterized in that a movable two-part plate (a) is arranged in the bus box between the boiler front and the bus flap, which is moved parallel to and from the boiler front by a movement device and held in place by a locking device during operation can. z. Movement device for the draft regulator according to claim i, characterized by a spindle screw (f) with an associated sleeve (g) which is riveted to the plate (a), whereby the plate can be moved on pins (c) parallel to angle iron (b). 3. Locking device for the draft regulator according to claim i, characterized by a screw (s) with a cross piece (o) which leads through a claw (p) attached to the upper part of the plate or engages around the same.
