Abstract

The invention relates to a panel water heater of a steam boiler, which solves its support, suspension, as well as mutual expansion of its panel blocks. The essence of the invention lies in the fact that the panel blocks are placed on support beams interconnected by suspension rods, which in the upper block are attached to the outlet chamber of the panel water heater, while the outlet chamber of the panel water heater is suspended from the ceiling of the bridge structure of the boiler by special hangers.

Description

(54) Panel water heater

The invention relates to a panel water heater of a steam boiler, in which its support, suspension as well as the separation of its panel blocks are solved.

SUMMARY OF THE INVENTION The panel blocks are mounted on support beams connected to one another by suspension rods which are fastened to the top block of the panel water heater at the top block, the panel heater outlet chamber being suspended by special hinges on the ceiling of the boiler construction.

FIG. 3,

The invention relates to a panel water heater of a steam boiler, in which its support, suspension and mutual separation of its individual panel blocks are provided.

The use of panel water heaters made of mutually welded tubular coils and flat steel rods has long been known. In most cases, these newly designed heating surfaces require support beams for placement in the flue gas ducts of the steam boiler. These beams are either part of the boiler support structure or are anchored in suitable manner to the flue gas ducts formed from the membrane walls. There are known cases of hanging the water heater panels directly on the diaphragm walls or also on hanging pipes specially led for the purpose between individual panels. Each of the aforementioned methods of suspension or support has certain disadvantages which, to a greater or lesser extent, negatively affect the operational reliability, mountability and, above all, the repairability of the water heater panels.

In the case of fixed blocks consisting of water heater panels on the beams of the supporting structure of the boiler, arise. dilatation problems, hanging on the side walls of the flue gas draft may cause unpleasant vibrations of the panels by the flue gas flow and in wider blocks also damage to the hinges due to panel instability. allow also movement movements of panels and good dismountability.

These drawbacks are overcome by the panel water heater according to the invention, which consists in that the panel blocks are supported on supporting beams interconnected by hanger rods, which at the upper panel block are fastened to the water heater outlet chambers, the outlet chambers being suspended by special hinges on the ceiling. boiler support structure.

By supporting the panels of the water heater blocks with supporting beams which are interconnected by suspension rods, a smooth transfer of the weight of the individual blocks to suitable dimensioned outlet chambers of the panel water heater is achieved. In this case, therefore, the outlet chambers also function as suspension beams ideally cooled by the working medium. Further, the absence of the gutter tube assembly of the water heater panels well accessible from the slopes (after cutting out the back tube of the second flue gas draft). The replaceability of the panels is also made possible by the easily removable platforms of the rear wall of the steam boiler.

The accompanying drawings show: FIG. 1 in section A-A, FIG. 2 is a schematic diagram of the fluidized bed steam boiler in sections B-B and C-C, indicating the location of the panel water heater. In FIG. 3 and FIG. 4, sections A-A and C-C show in detail the blocks of the panel water heater showing the support and suspension system.

The working medium - feed water is transferred to the panel water heater 1 through the inlet chamber 2 through the transfer tubes 3 to the lower panel block 4. From this further through the connecting tubes 17, successively through the middle panel block 5, the connecting tubes 17 and the upper panel block 6 into the outlet chambers 8.

From these outlet chambers 8, the working medium is fed through the transfer tubes, either to further heater blocks or directly to the boiler body. The panel water heater 1 is located in a second flue gas draft 10 bounded by membrane walls 9 reinforced by platform bandages 16. The panel water heater 1 consists of panel blocks 4, 5, 6 supported on support beams 13 which are interconnected by suspension rods 12 extending to to the outlet chambers 8 to which they are detachably connected. The outlet chambers 8 are suspended by special hinges 11 on the ceiling of the boiler support structure. by means of rulers 14, to maintain their spacing along the width of the flue gas channel 10.
