Abstract

Invention mb, used in low power plants operating on liquid fuel. The purpose of the invention is to increase the stability of the installation in a wide range of modes. The vertical furnace 2 is framed by a water jacket and is enclosed together with the exhaust pipe 3 in leather 4 with the formation of an air channel 5. Channel 5 is connected to the atmosphere at the level of the upper cut 6 of pipe 3 located above the roof 7 of the car and in the lower part with air supply Channel 8 of the firebox 2, made in its bottom. Channel 8 has a confused diffuser profile and with the formation of an annular gap 9 an active nozzle 10 is placed with an adjustable lower opening 11 communicated with the atmosphere outside the car 12. In the installation it reduces the average level of t-ry coming from the channel 5 of air, which increases mt gu. In addition, fire safety is increased and load regulation is provided without disturbing the currents across the installation path. 1 il. C

The invention relates to low-power heating installations operating on liquid fuel and equipped with evaporative burners used, for example, for heating diesel-utility vehicles of refrigerated rolling stock with,

The aim of the invention is to improve the stability of operation in the world of operation;

In the drawing of a schematic picture of the sham, the proposed heating system of the car.

The heating installation of the car is accompanied by a framed vertical waterpl I TOCP7 / 2, equipped with a chimney 3 and enclosed amesta with pipe 3 in the casing 4 to form an air channel 5 communicating with the agrosphere at the level of the upper section 6 the exhaust pipe 3 located above the rail 7 of the car, and in the lower part, with the air supply channel 8, is thin 2j filled to its bottom. Channel 8 has a confusor-diffuser profile ;, Air supply channel 8 is provided with an active nozzle 0 with an adjustable opening 11, which is connected to the atmosphere beyond the carriage, with an annular gap 9 located therein. 12 ,, In the bottom of the furnace 2, there is also installed the evaporative Zlka 13,

Heating car installation works as follows

The air taken in at the level of the upper section 6 of the exhaust pipe 3, the passage through the air channel 5, is first heated by the flue gases, then partially releases heat to the water in the water jacket 1. and flows through the air supply channel 8 to the evaporator burner 13 of the furnace 2 In the forced modes, the active nozzle 10 opens, communicated with the atmosphere outside, outside of the car 12, The inflow of cold air supplied by CHisTy additionally ejects the heated air drawn from the top. As a result, in all modes, high fuel quality is achieved. Constructive solution of the heating installation reduces the average temperature of the air coming from the air channel 5 :; which increases traction, besides, fire safety is increased and it is possible to regulate the load without disturbing the currents in the path of the heating installation.

The heating installation of the car, containing a framed water scrub-vertical furnace, is fitted with a chimney and enclosed with the latter into a casing with the formation of an air channel communicated with the atmosphere at the level of the upper section of the chimney located above the car's roof, and in the lower part - with the air supply channel of the firebox, made in its bottom 5, differs ayuchu with the fact that, in order to increase the stability of work in a wide range of modes, the Air supply channel of the firebox is filled with confusion-diffuser profile and It is placed in it with the formation of an annular gap by the active nozzle with an adjustable lower opening, communicated with the atmosphere outside the car.

Claims (1)

Claim A heating installation of a car, containing a vertical firebox framed by a water jacket, equipped with an exhaust pipe and enclosed together with the latter in a casing with the formation of an air channel in communication with the atmosphere at the level of the upper cut of the exhaust pipe located above the roof of the car, and in the lower part with the air supply channel of the furnace carried out in its bottom, on behalf of me, so that, in order to increase the sustainability of the work! in a wide range of modes, the air supply channel of the furnace is made of a confuser-diffuser profile and is equipped with an active nozzle placed in it with the formation of an annular gap with an adjustable lower opening communicated with the atmosphere outside the carriage,
