The disadvantages of the known steam boilers are: slow heat transfer from the heater to the water, uneven heating of the boiler is more bottom, top, less, low rate of evaporation, considerable heat loss.
These drawbacks are due to: the low thermal conductivity of the material of the boiler, the steam is mainly in the lower part of the boiler, low efficiency, quick dissipation into the surrounding space, the resistance to movement of the pair in parosbornoj through a section of the boiler, as well as the design of boilers.

The disadvantages of the known steam boiler, taken as a prototype, the same.
These drawbacks are due to the design of a steam boiler.
The aim of the present invention is to improve the performance and efficiency of a steam boiler.
The objective according to the invention is ensured by the fact that the longitudinal axis of the furnace is shifted downwards relative to the longitudinal axis of the cylindrical drum, and the furnace has the shape of a hollow cylinder, closed on both sides with covers on the top arch of which is made at some distance from each other in longitudinal and transverse directions of the rectangular cross-cutting channels into which is inserted and welded to the upper arch of the furnace heat transfer device installed so that the longitudinal axis of each of them lies on the line of the radius of the furnace and passes through the center of the circle the last, and the heat transfer device is made in the form of heat pipes, each of which has a rectangular hollow the box to which is welded on the top and bottom covers, and inside each Teplov the th pipe liquid filled 1/4 of the volume through the hole in the top cover, closed tube, and the lower part of the heat pipes, which are zones of heating and evaporation, go to the combustion space, and the upper part of the heat pipes, which are zones of cooling and condensation, are fan-shaped in the upper part of the cylindrical drum, washed with water and have cooling fins.
The invention is illustrated by drawings, where figure 1 shows a General view of a steam boiler, the figure 2 - view of the steam boiler front, on the figure 3 - view of the steam boiler side view in section, in figure 4 - view of the steam boiler front section of the figure 5 - General view of the heat pipe in the section, figure 6 - view of the heat pipe side view in section, in figure 7 - principle of the heat pipe.
Steam boiler comprises a cylindrical drum 1, the furnace 2 ash 3 and grate 4. The furnace is closed the front 5 and rear 6 caps. The longitudinal axis of the furnace is shifted downwards relative to the longitudinal axis of the cylindrical drum has the shape of a hollow cylinder, closed on both sides with covers on the top arch of which is made at some distance from each other in longitudinal and transverse directions of the rectangular through-channels. On the front cover of the furnace installed nozzle 7 for supplying liquid fuel. The ashtray is closed by a cover 8, and the rear part has a nozzle 9 for removing water slag pritoplennye steam boiler with solid fuel. In the rectangular through-channels of the upper arch of the furnace is inserted and welded heat transfer device installed so that the longitudinal axis of each of them lies on the line of the radius of the furnace and passes through the center of the circle of the latter. The heat transfer device is made in the form of heat pipes 10, each of which has a rectangular hollow frame 11 to which are welded at the top and bottom covers 12 and 13, the inside of each of them poured the liquid 14 1/4 volume of the heat pipe. The liquid is filled through the opening in the top cover, closed by a plug 15. The lower part of the heat pipes, which is a heating zone of evaporation, go to the combustion space, and the upper part of the heat pipes, which are zones of cooling and condensation, a fan located in the upper part of the cylindrical drum, washed with water and have cooling fins 16. In the upper part of the cylindrical drum is parosbornoj 17, through which the pipe 18 is connected to the superheater 19 arranged in the duct 20 connected to the exhaust pipe 21. In the upper part of the cylindrical drum mounted socket 22 water supply and placed in front water gauge glass 23.
When the heating steam boiler liquid or solid fuel inside the combustion chamber 2 there is a high temperature. The upper arch of the furnace heats up and heats the portion of the water, which the traveler comes across it. Simultaneously heats the lower part of the heat pipes 10, which are located in the combustion space. Liquid coolant in them boils and evaporates by absorbing heat rises and there is condensed with evolution of heat, which, through the duct 11 and the ribs 16 is transferred to the surrounding water, which boils the entire volume, and the steam is collected in pasborice 17 (Fig.7). The movement of vapor in the heat pipe 10 is due to the differential pressure saturated steam, defined by a temperature difference in the heating zones-evaporation and cooling and cooling-condensation. Return the liquid in the heating zone of evaporation is due to gravity on the walls of the heat pipes (figure 7 arrows). Thus the effective thermal conductivity of the heat pipe is much greater thermal conductivity of copper, silver or aluminum. Large heat fluxes and their location throughout the volume of the steam boiler, the large surface of the ribs 16 can cause rapid boiling and evaporation. While much of the heat has time to go for water heating. /About heat pipes, see Physical encyclopedic dictionary, editor-in-chief Amerkhanov, M., Soviet encyclopedia, 1983, s/. From parosbornoj 17 steam through the pipe 18 enters the superheater 19, where it is draining and additional heating, then he passed to consumers. Gas the initial flow from the chamber 2 moves into the flue gas duct 20 and further through the pipe 21. When the heating steam boiler with solid fuel ash through the grate 4 falls into the ash chamber 3, from which it is removed by a strong jet of water supplied from the nozzle 9 when the cover is open 8. The flow of water in the boiler is filled through the pipe 22, and monitoring of water levels through water gauge glass 23.
We offer steam boiler can be used on marine vessels, power plants, especially mobile, and for heating of residential buildings.
Positive effect: simple design, a more complete and rapid use of the generated heat more uniform heating of water throughout the volume of the steam boiler, higher productivity per unit of time, a higher service life due to the absence of flame and fire tubes.
