Description

A drumless serpentine high-pressure water-flow steam boiler.

It was announced on September 15, 1932 for number 115748.

Known drumless serpentine high-pressure water-tube steam boilers with a heating surface formed by coil coils located in the combustion space, made of one or several parallel tubes in the form of a ribbon beam.

In the proposed boiler, in order to achieve the same and uniform heat load of all pipes, the combustion space is divided into several cells with coil loops, which form screen partitions of pipes lying in the same plane, and the number of separate continuous single-tube or beam coils corresponds to the number of said cells . These coils constitute a kind of multi-way screw, so that each pipe or bundle, having made only one loop in any cell, passes into the neighboring cell to obtain a loop that is offset from the plane of the previous loop. As a result of such a device, each coil pipe passes through all temperature zones of the flue, and therefore everything is published on November 30, 1938.

pipes get the same heat.

In the schematic drawing of FIG. 1 shows a cross-section of the boiler at the entrance of the coil pipes to the boiler; FIG. 2 is a cross-section of the boiler at the exit of the coil pipes into the upper collecting headers; FIG. 3 and 4 - vertical sections of the upper part, the boiler in two mutually perpendicular directions; FIG. 5 - the location of the coils in any section of the flue; FIG. b - side view of the coils in the unfolded state.

Water (or other evaporated liquid) is continuously supplied from the feed pump through the corresponding valves into two junction boxes / 7 (Fig. 3 and 4), from which the hanging pipes / 2 (in the description of the boiler placed here, for example, accepted the thinness of the pipes, but their number may be different), then, climbing up the six pipes 13 (Figs. 1, 2, 3) and once again descending through the six pipes 14 rises last time through the six pipes / 5 and enters again in two prefabricated boxes / 6 of which

It is directed through pipes 7 (directly or through a conventional heater or economizer of the usual type) to distribution manifolds 2, of which each branches into twelve pipes 3 (Fig. 1). These pipes in each stream are divided (Fig. 3) into three groups 4 (four pipes 8 each), coming out of each collector 2 into the boiler coils in three horizontal planes; consequently, from both collectors, they are included in six horizontal planes with four pipes in each plane. Four tapes of six pipes originate in a vertical section (Fig. 3) by entering into six horizontal planes of four pipes and, in plan (Fig. 1), by entering eight rows of pipes 5 (four from each collector) in eight vertical planes, three pipes in each vertical plane. The resulting four pipe bands of six pipes each form in plan four quadrants I, II, III and IV, each of which has separate pipe coils. They have a continuous lift and a different direction (Fig. 1 and 2), i.e. JB quadrants I and IV are counterclockwise and in quadrants II and 111 are clockwise. Thus, pipe coils are a four-rod four-way and six-screw screw system.

In a gas flue duct, each pipe with a continuous (insignificant but sufficient to prevent gas or vapor bubbles from getting stuck) is lifted upwards and in any place of the shaft has the shape and location indicated in FIG. 5 in plan and in FIG. 6 - in the form of a schematic scan in vertical projection. In these figures, the four sides of each quadrant I, II, III, and IV are denoted by / 7, J8, 19, and 20. Arrows circled around the numerical designation of quadrants indicate the direction of curling of the turns of each quadrant.

Obtained in the boiler part of the unit four pairs lying

in the vertical planes of the rows of pipes 2 / (fig. 2), six pipes in each row (i.e., only twenty: four pipes) are output to twenty-four tee boxes 22, of which, after twenty-four, valves 23 fall into prefabricated manifolds 25. To each of the tee boxes 22, purge valves 24 are connected, each having the purpose to blow each of twenty-four boiler coils separately by releasing steam or water from them, for which one or the other coil is disconnected from the collector 25 23. The same valve Whether 23 is also provided for adjusting the resistance to the passage of water and steam through each of the twenty-four boiler tubes separately. Of the two prefabricated collectors, 25 pairs of four external bypass pipes 26 are converted into two lower distribution steam collectors 27 (Fig. 1), of which twenty four pipes arranged in two rows 28, it again goes to the four lower six pipe lengths 29 (Fig. 4) radiation overheater. These overheating tapes also form a four-rod four-way six-screw system and differ from the boiler coils described above only by the diameter (in accordance with other steam speeds and allowed thermal loads) and vertical pitch. In the horizontal projection, the superheater coils are located equally with the boiler houses, forming the same four quadrants, which, together with the boiler plants, divide the entire flue gas duct along its entire height into four separate shafts, each only limited from all sides by the pipe walls: in the upper part are the boiler rooms and in the lower part - overheating. The pipes 7 and 5, which form the outer walls of the quadrants (Figs. 1 and 2), are located at a certain distance from the laying of the flue duct 30 so that they are exposed to radiation from all sides, namely: from the inside -

direct emission of gases and outside - reverse emission of masonry. The inner sides of the 9 and JO quadrants are formed from the constituent two vertical rows of pipes that one row is shifted relative to the other by half the diameter in order that due to this, each pipe will be completely illuminated from both sides and will perceive the radiation emission from its surface of two adjacent adjacent schacht.

The described device is aimed at obtaining such an arrangement in which all pipes, passage through all temperature zones of the duct (not counting the practical temperature difference at the height of one schag), had the same thermal load and therefore gave almost the same amount of steam, with the same speed, consumed the same amount of water, gave the same nature of vaporization (uniformity, etc.), the same condition of the inner and outer surfaces of the pipes, etc. In addition, the invention has. The goal is to achieve one more advantage, namely, that all the boiler chuby and superheater not only receive heat radiation, but at the same time they are washed with hot gases, for which the pipes are located not only at the masonry walls, but also share the entire flue chamber by the number of individual mines (separate parallel running ducts), which would result in sufficient washing of the tubing surfaces bounding these schasthas with gases. The number of schachts (and hence the number of individual tube quadrant cells) is not necessarily four, but maybe

any multiple of two or four and depends on the design parameters and the -POWER of the entire unit.

The subject matter of the invention.
