Description

IMPERIAL

PATENT OFFICE.

The construction of this new steam generator is based on the following requirements.

The steam generator should:

ι. above all, with. Exclusion of Risk of explosion, to be used for high vapor voltages,

2. offer the largest possible heating surface in a small room,

3. Wide areas for fire, thin layers of water, and large evaporation surfaces Offer,

4.-, provide dry steam,

5. be suitable for any fuel (the same should be degassed on the grate and the combustion gases should be mixed with air to be as complete and smoke-free as possible Incineration),

6. Be cheap to manufacture, allow repairs to be easy and be as simple as possible Require operation.

The principle pursued for the generation of steam is shown in FIG. 1 in vertical and horizontal sections illustrated single element.

A tube α, which has cross-pieces at the top and bottom for connection to other elements, also has a Bpgenstutzen h ¹ at the bottom, on which a shell 1 is placed in the manner shown. In the same way, further 'shells 2, 3, 4 etc. are built up on this up to the level of the pipe on which a tab with the pressure screw 5 is seated at the top. By means of this pressure screw, all the shells are pressed onto the sealing rings inserted in the seats.

The upper shell is continuously fed through the feed pipe r. The water level in the bowl is slightly above the middle of the bowl. The next lower evaporation dish extends with its neck h into the upper evaporation§ | ej | ä.le up. The neck contains "a soap stick , which, shorter than the neck itself, begins at the level of the water level in the upper bowl and bends in its own bowl below, so that the water flowing through into the bowl itself and not into the neck The following bowl falls. In this way, all the evaporation bowls are lined up one on top of the other.

The steam formed in each individual bowl pulls down through the neck of each subsequent bowl, which protrudes above the water level, and collects in the tube a. Excess water fed in or mechanically entrained is collected in the cross tube t and returned to the feed water reservoir through a condensation water drain.

The collected steam is dried even more as it rises in the collecting pipe α , possibly overheated, and is fed to its place of use ^{from the upper cross pipe f 1 through a side connection.}

The feed pipe r is through the .. pressure screw s pressed.

The assembly of a steam generator from individual elements in a round shape shows the Fig. 2 in plan and vertical section, and thus at the same time the device for degassing of the fuel and the smokeless combustion of the same.

For the sake of clarity, the arrangement of the vapor collection tubes is in the vertical section in ■ laid the same cutting plane with the evaporation dishes, it is therefore the diameter larger than the basic riff.

A base u carries the grate, which can be opened downwards, as well as a chamotte firebox.

The steam containers α are connected by ribs (see the basic riffs) and form a closed furnace. The vertical tubes a are connected at the top and bottom with the horizontal tubes i ¹ and t .

The furnace formed in this way sits on the foundation u . The evaporation dishes are grouped concentrically around the furnace.

A pipe R rests on the furnace by means of a cast smoke hood and extends down into the combustion chamber, with a stronger retort attached to the bottom. The latter is, since it is subject to greater wear, easily replaceable. A cast pipe i leads the combustion products from the smoke hood to the chimney. A cover T closes off the top of the tube. The same is broken through, and a slide can be used to regulate the entry of air into the retort from above. The fuel is fed through the pipe R from above !; ^; 'As soon as the fire catches on fire,' the fuel in the retort heats up and is degassed. The gases are mixed with air from above and are burned in the combustion chamber.

The feed water is fed by a feed device continuously through the preheater V into the distribution pipe r , which distributes it evenly into the upper evaporation dishes.

In the manner described, the water falls from bowl to bowl with the rising heating gases opposite.

Claims (4)

Patent claims: For the steam generator shown in the drawing and description: 1. The single element, consisting of a spherical, bottle-shaped hollow body with Split neck for separate water and steam routes. 2. The connection between the individual evaporation dishes and with a vertical one Steam collecting and drying tube in such a way that the first bowl rests on a connecting piece of the latter, on this the second and so on, while the whole row of shells is secured by a pressure screw which is in one arm sits at the top of the steam collector tube, is held together. 3. The supply of the feed water through an annular pipe and the distribution of the same in the upper shells of the steam generator. 4. The overall arrangement of the basic elements around a central, smoke-consuming filling furnace to a closed whole. 1 sheet of drawings.
