SU902A1 - Water tube boiler for central heating - Google Patents

Description

The proposed boiler consists of straight vertical or almost vertical hot water pipes connected by j at the bottom and top of the chambers. The main reason for the good effect of central water heating is the proper circulation of water both in the system and in the boiler itself. It is best to circulate in the vertical direction of the Research Institute, where the rise is heated and the fall | chilled water meets least resistance. 1

To increase the flow rate j of water in the pipes of the proposed boiler, the lower and upper chambers are also divided into two parts, j The attached drawing shows the proposed boiler in a vertical longitudinal (in Fig. 1) and transverse (in: Fig. 2) cuts and in the plan (Fig. 3). ;

The upper 3 and lower 2 chambers of the boiler, j interconnected by vertical hot-water pipes, are divided by t partitions into two parts, as shown in FIG. 1. Therefore, water like; in the left group of pipes 1, and in the right group of them, they have a natural upward movement with heating and only; in one row of pipes 1 connecting I

left and right group, the water goes down. The left-hand group of pipes is separated from the right-hand group of pipes by a thin wall 15 of schamotoy bricks. Gases from the furnace 8 go upwards along the pipes of the right group, and then down at the pipes of the left group, and from there to the LL burs. The cooled water from the system flows through pipe 4 to the left part of the lower chamber 2, from where it rises through pipes 1.1 to the left part of the upper chamber 5, then descends along the row of pipes 1 into the right part of the lower chamber 2 n through pipes 1.1, rises into the right part of the upper chamber o and through pipe 5 leaves the boiler. Downpipes 1 1 can be placed outside the boiler lining and replaced with one downpipe.

The main heat transfer occurs in the pipes of the right group, while the left group of pipes is like a heater.

Boiler chambers can be iron riveted or steel cast. Pipes 1.1 flared in the walls of the chambers. The bottom of the lower chamber 2 and the lid of the upper chamber 3 are attached to the bolts so that they can be removed to clean the pipes from the inside of the scale. The bottom cleaning chamber for cleaning the scale is equipped with hatches 27, and for flushing the boiler with a drain pipe 6. The pipes 1.1 are arranged in a staggered order, but there are through spaces between the pipes through which from the doors 22 in the side brick walls of the boiler be cleaned of soot, even on the go boiler. Chambers can be lined with bricks to reduce heat loss from emissivity. The gigs 23 and pillars 24 fasten the brickwork of the boiler.

Fuel is loaded from the top through two openings, 9, closed by sand shutter flaps 17. The loaded fuel (maybe brown coal, peat or firewood) while it is in the furnace 9 before it enters the fire zone 19, where it moves as the lower layer burns, is exacerbated by radiant heat. In case of high quality fuel

The furnace can also be arranged inside the boiler, as shown by dotted line S6 in FIG. 3. Then, instead of a part of the pipes, a firebox is placed, and the upper and lower chambers receive the corresponding notches 26 in the dotted line.

SUBJECT OF THE PATENT.

Water-tube boiler for central heating, with vertical or slightly inclined pipes, connecting the divided partitions of the chamber, and with an internal brick threshold dividing water heating pipes into two groups, characterized in that the partition in the upper chamber is placed between the first and the second (counting from the firebox) groups of pipes, in the lower chamber the partition is placed between the first row of the second group of tubes and their subsequent rows, and the first row of the second group of tubes can be moved out of the obstruction to the outside as one or Some pipes.
