Description

The proposed boiler, which is a type of continuous boilers, has a water-fired furnace with vertical flue pipes inside the casing to provide water circulation with an external pipe connecting the internal space of the casing of the boiler with a bottom valve that opens only when the pressure rises and water temperatures in the boiler, and to increase the heating surface with pipes inserted into the heat pipes.

In FIG. 1 shows a vertical section of a boiling kettle along the line ABCD of FIG. 3; FIG. 2-part return pipe; FIG. A 3-horizontal section of the boiler along the line AD of FIG. one; FIG. 4-side view of it; FIG. 5 is a horizontal section of it along the line EF of FIG. four.

The boiler works on the principle of a fire-water-tube boiler and consists of 3 cylinders 1, 2, 3, connected to each other by bolted flanges, with a kinderterovy cardboard or rubber gasket. The cylinder at the top and bottom is covered with spherical caps and rests on an iron riveted pedestal 5.

Inside cylinder 1 was riveted iron; on the outside, a carefully used firebox b, resting from its rear

part on the square a. In the rear upper part of the firebox, several iron pipes are welded outside the well-groomed pipes, the upper ends of which are rolled into the pipe, board L of the bottom of the housing.

Combustion takes place on a cast-iron grate with, flue gases behind boron d mix with additional air, from a blower through valve e and through pipes / enter chamber 3, where they change direction, receive a different (lower) speed and through pipes g outside tinned and flared in tube sheets b, b come into chamber 2, from where they are diverted to atmosphere by chimney 7. On its way, the gases give off heat to the outer surface of the tubes f VI g to the water filling up to the top of the middle cylinder 1. In addition to the outside. the surface of the pipes f to g the water in the cylinder 1 receives heat from the outer surface of the furnace 6.

Inside iron pipes g, iron pipes K, flared in pipe racks A and / ii, are connected and connect the upper and lower spherical caps 4. Water comes from pipe bottom M through water supply pipe or another reservoir located above the boiler in such a way so that the water fits no less, like: with a pressure of 0.5-1 atm. Filling the lower cap 4, water through pipes L

It is placed and fills the upper cap 4 and from it through the return water pipe L expanded into the tube plate L, fills the middle cylinder 1, and the air is removed through the pipe "tap 8". The tubes K are inside filled with water and outside subjected to the heat of waste gases, transfer the heat perceived by their outer surface to water.

The circulation of water in the apparatus is carried out through the tube O and the valve / 7: while the system is filled with water from the reservoir or from the water supply system, the check valve P is closed with a water pressure of 0.5-1 atm. As soon as water heats up to 80 - 100 °, the pressure in cylinder 1 is comparable to the pressure in the receiving pipe "M and the valve // will open under the influence of its weight.

Further, as the water temperature rises to at least 105 ° C, the pressure in pipe O will exceed the pressure in pipe L / and hot water will begin to flow into the lower sphere and through pipes K. and the return pipe L will be installed. water circuit. As soon as the water is heated to 100 °, water from the boiler can be disassembled through the faucet on the receiving tube, without worrying about replenishing it, since it will automatically be filled with water, which by the time of mixing with the boil will already be heated to almost boiling point.

To prevent heat loss to the outside, the entire body of the boiler is smeared with poorly conducting substance (kieselgur or asbestos) with a thickness up to and over the layer is lined with wood strips.

The subject of the patent.

A boiler consisting of a cylindrical body with convex bottoms at the top and bottom, inside of which a firebox with vertical flue pipes is fixed, washed with water, characterized in that inside the flue pipes g another pipes k of smaller diameter are inserted for the passage of water and that the internal space of the housing 1 connected to the space of the lower convex bottom 4 by means of an outer tube O with a valve P opening under the action of its weight and intended for the circulation of water only when the pressure and temperature of the water in the boil are raised nike.
