Applicant: Strebelwerk G.m.b.H., Mannheim, Hansastraße 63 Warmwater articulated boiler

The invention relates to a sectional hot water boiler. In boilers of this type, it is customary to have a flow that is as strong as possible to strive for. A main means of doing this is to achieve large temperature differentials. In contrast, according to the invention the temperature differences are kept small and the flow velocity is reduced. Εε is aimed at that the vapor bubbles that arise in the water space still condense within the water.

A major advantage of such an arrangement is that overheating does not occur at any point in the boiler lead to the locally preferred formation of scale. Rather, "with a boiler according to the invention, there is uniform heating and thus a uniform elimination of any scale that may be present. With such a uniform deposition local overheating of the boiler wall is not to be expected fear.

According to the invention, the unclad inner walls of the boiler sections facing the plam chamber slope upwards in

In particular, it has proven itself to wipe the edges of the boiler sections, which have returned to the fire room, wipe the sealing strips to bulge out towards the flasun area, whereby these bulges emerge over the goose furnace

In the vertical plane A, the plaque axis 1. L ± e is preferably at the bottom. It is enclosed by the protruding Keasel walls 2 with the sealing ribs 3 which are set backwards. The interspaces between the inner turns of the boiler sections can become larger towards the top, as indicated at A.

While the lower and side furnace walls 2 are not clad, a cladding 5 »6 ac rear member 7 is provided, which engages in a sickness 6 of the rear member. This cladding directs the fire gases upwards into the spaces 4 and laterally the fire gates are guided on the one hand through the hip 3 and on the other hand through a guide surface 9 adjoining the upper hubs, which works out with a corresponding guide surface of the symmetrical half. The Feuerga ·· then enter the channel 10, which runs from the back to the front. A cover body 11 ensures that not all of the sutras pass over immediately into the section of the duct which is reached most immediately, but that the fire gases are distributed over the length of the convection chamber. An inner subspace 12 and an outer subspace 13 for the water are formed in the keel members and. Both sub-spaces are connected by an outwardly rising Eohra H eit * inejid r. In this way the water will be replaced with any bubbles that may have formed

In this way, wearing of harmful materials is avoided here.

In the case of the boiler according to the invention, a uniform abrasion of the boiler stone resulted, so that practically no "cleaning" was necessary. The cauldron gave way to the outside a very good specific hot surface load.
