RU2002172C1 - Hot-water boiler - Google Patents

Description

The invention relates to heat engineering, in particular to heating devices, and can be used in boilers for heating systems of individual residential buildings and industrial premises.

Known hot water boiler containing a combustion chamber, framed by a water jacket. Air is supplied under the grate jacket through a manually openable blower door. To regulate the process of fuel combustion, a gate is installed in the smoke channel.

A disadvantage of the device is manual control of the fuel combustion process, which requires constant monitoring.

A hot water boiler is also known in which automatic adjustment of the air supply under the grate is provided. For this purpose, the boiler is equipped with a thermostat of combustion mode, connected with the actuator of the motion transmission of the blower, made in the form of a rod suspended on a lever mounted in the openings of the regulator body. When the water temperature changes, for example, when the temperature rises, the lever under the influence of the temperature regulator covers the blower flap.

The technical solution closest to the invention is a hot-water boiler containing a firebox placed in a body in the form of a water jacket, connected to a smoke pipe, a temperature regulator equipped with a sleeve and fastened to the support by a lever fixed through the suspension axis with the support. The end of the lever is connected to the air damper by means of a tie, T ha is pulled through a guide tension roller, which rotates in an arm fixed to a portion of the boiler wall exposed to temperature through a melt pad.

When the set temperature is exceeded, the gasket melts, the tension roller disappears, the tension is removed and the automatic cover closes.

The disadvantage of the latter devices is that it is practically impossible to seal the perimeter of the air damper when it is completely closed, and if there is a vacuum in the furnace created by the exhaust pipe, constant air intake into the combustion chamber is maintained, which supports the combustion process, i.e., fuel consumption is not shrinking.

The purpose of the invention is to increase the reliability and accuracy of control of the combustion process and fuel economy.

The goal is achieved in that the boiler containing the firebox placed in the body in the form of a water jacket is connected to the chimney, a thermostat is provided with a sleeve and fastened to the support by a lever fixed through the suspension axis with a support, while one end of the lever is connected to the air damper by means of a thrust, further comprises a sliding gate installed in the chimney, tg is connected to the free end of the lever in which the through groove is made, and the thermoregulator sleeve is movably mounted and connected and with the lever by means of a pin fastened to the sleeve and installed in the through groove of the lever, while the support is fastened to the housing.

The pin is mounted in the through slot of the lever with the possibility of movement.

T ha of the gate is equipped with a spring and a rack gear, the gear of which is connected to the gate.

An insulated cavity is made in the boiler body, in which the throttles of the air damper and gate are placed.

The movable sleeve, acting on the pin, drives the lever, which changes the passage sections of the blower and the smoke channel. In this case, the amount of air supplied under the grate is limited both by reducing the gap between the flap and its plane of fit, and by reducing the vacuum in the furnace by creating a pressure of the back-up of the gas medium, which is provided by hydraulic resistance to the movement of the exhaust medium through gate This makes it possible to better regulate the ratio of fuel and air and, after reaching the set water temperature, to reduce the rate of fuel combustion, i.e., to conduct the process of fuel combustion economically.

In FIG. 1 shows a boiler, longitudinal section; in FIG. 2 - section AA in FIG. 1; in FIG. 3 is a section BB in FIG. 2; FIG. 4 is a section BB of FIG. 2.

The hot water boiler (Fig. 1) contains a furnace 3 located in the housing 1 in the form of a water jacket 2; connected to the smoke pipe 4, a thermostat 5 (Fig. 3), equipped with a sleeve b (Fig. 4} and fastened with a support 7 to a lever 8, fixed through the suspension axis 9 with a support 7. One end of the lever 8 is connected to the air damper 10 mounted in the ash chamber 11 by means of a rod 12 with a spring 13 connected to the lever 14. Transmitting movement when the lever 15 is exposed to the damper 10 through the spring stop 16 connected with it. A gate 17 with a thrust 18, with integral with the free end of the lever 8, in which the through groove 19 is made. The sleeve 6 of the temperature regulator 5 is movably mounted and connected to the lever 8 via a pin 20. fastened to the sleeve 6 and installed in the through groove of the lever 19, while the support is fastened to the housing. The pin 20 is mounted in the through groove of the lever 8 with the possibility of movement when changing its position. To transmit the movement to the gate, the rod 18 is equipped with a spring 21 and a rack gear 22, the gear 23 of which is connected by a gate. An insulated cavity 24 is made in the boiler body, in which the throttles of the air damper and gate are placed. When the temperature of the water rises at the installation site of the temperature regulator 5, the volume of the working fluid e the thermoballon 25 (Fig. 4) increases, the pressure acts on the bellows 26 and begins to move the rod 27, which, moving, rests on the handle 28 and raises the movable sleeve 6. The sleeve associated with the pin 20 rotates the invention.

1. A WATER BOILER comprising a firebox placed in a body in the form of a water jacket, connected to a chimney, a temperature regulator equipped with a sleeve and fastened to the support by a lever fixed through the suspension axis with a support, while one end of the lever is connected to the air damper by gig, characterized in that, in order to increase the reliability and accuracy of regulation of the combustion process and fuel economy, it additionally contains a gate with a thrust mounted in the smoke pipe, while its thrust is connected to the free end of the rye chaga in the last a chag 8 around the support 7. The lever, turning, sets in motion the drive mechanism of the damper and gate, which gradually increase as the water heats up to the set temperature they cover the passage sections of the blower and the smoke channel, which ensures regulation of the air flow into the furnace, regulates the combustion process of the fuel and leads to its economy. When the temperature decreases, the rod 27 moves in the opposite direction, under the action of the spring 21, the sleeve b returns to its original position and the lever 8, turning, starts to open the passage sections of the blower and open smoke channel. The flow of air into the furnace increases, the fuel combustion process intensifies again and the temperature of the water increases.
