Description

WATER BOILERS

The invention relates to water heating systems and hot water supply and can be used B systems with individual heating for buildings of different heights and located outside the building.

A boiler plant is known, comprising a boiler equipped with a contact air heater and an economizer, connected in parallel to the supply and exhaust lines to the heating paths of the heat network and the surface heat exchanger, the heating path of which is connected to the contact air heater and equipped with a flow regulator, and the economizer is connected to the boiler supply line, the installation also contains air temperature sensor (see A.S. USSR id I 666 855, class F 22. D 1/36).

The disadvantage of this installation is the high cost of its manufacture, cumbersome.

Also known are boiler plants consisting of a boiler in the upper part connected to the economizer by a direct heating line. These plants utilize the heat of the flue gases of solid, boiler and gaseous fuel boilers, while simultaneously allowing water to be heated from a domestic drinking water supply (see industrial boilers DE, DDDR, EB-2-94,

The disadvantage of these boiler plants is the design complexity, high cost, cumbersome.

The closest in technical essence and the achieved positive effect and accepted by the authors for the prototype is a vertical hot-water fire tube boiler, containing a housing in the lower part of which there is a furnace with a burner

a device feeding and returning the tube, a flue gas removal pipe, while the upper part of the boiler is made in the form of a central tubular and ring-shaped chambers, which form an inner and outer annular vertical gas ducts with the inner diameter of the casing, while the lower part of the chambers is muffled, and the upper the part is connected to the boiler body, the internal gas duct is connected to the external and to the flue gas exhaust pipe and using a window, and the internal and external surfaces of the gas ducts are made in the form of cylindrical toobraznyh metal ribs forming helical ascending flues (see. US Pat. RF -2158395, cl. F 24 H 1/28).

The disadvantage of this boiler is the complexity of the design, the likelihood of a gas explosion and the possibility of destruction of buildings in boiler rooms and surrounding structures.

Technically, the result is: loab1; to be achieved in the implementation of the invention is reduced to simplification

the construction and reduction of the cost of heat production, and except for the possibility of explosion of probability, the destruction of boiler houses beyond

account for the installation of a boiler of buildings and structures.

The technical result is achieved using a well-known hot water boiler containing a fire tube part with an atmospheric gas burner device, a direct and return line, a chimney base with a soot cleaning device and flow restriction, while a fire tube part with an atmospheric gas burner device, a direct and return line, a smoke base pipes with a device for cleaning soot and a flow restrictor are placed inside a thermally insulated housing, the latter is additionally equipped with a door for servicing gas device and grille for the intake of external air, and

An automatic thermostatic shut-off and control valve is installed in a straight line of the cottage.

In FIG. I given a hot water boiler, general view.

In FIG. 2 same cut.

In Fig. 3, an automatic thermostatic shut-off and control valve is given.

The outdoor boiler consists of a hydro-insulated building I, having a door 2 for servicing a gas burner device, a grill 3 for air to enter combustion, a chimney base 4 containing a soot cleaning device 5 and a flow restrictor 6; a carotube boiler is installed inside housing I 7 with an atmospheric gas burner device 8, a straight line 9 and a return line 1C, in a straight line 9 an automatic thermostatic shut-off and control valve II is installed, consisting of a housing 12, inside of which installation of the hot water supply pipe from x-chl and the hot water supply pipe 14 to the heating system, in the housing 12. a thermostat 15 of type TC-IC7-GI is fixed, containing a seat 16, the housing 12 contains a removable cover 17 and a gasket 16; .

The boiler operates as follows.

The igniter is ignited (not shown in Fig.), And then the atmospheric gzogorelochny device 8 of the boiler 7 is turned on, the external air for combustion enters through the grate 3, heated in the upper part of the chimney 4 and the boiler 7, due to natural draft enters the atmospheric gas burner for combustion device 8. The boiler 7 is gradually heated to a temperature of 70-75 ° C while the automatic thermostatic shut-off and control valve II is completely closed, there is no circulation of the heat carrier in the heating system. When the water in the boiler 7 is heated above 7С (- С thermostat 15 starts to open the saddle 16 bypassing the hot

water in a straight line 9, circulation begins in the heating system. When the water in the boiler 7 is heated above 80 C, the valve of thermostat 15 is fully open. Depending on the amount of heat received from the boiler 7, the valve of the thermostat 15 can occupy any intermediate position, automatically maintaining the set temperature of the water in the boiler 7 and providing any operating mode

heating systems, including stand-by heating. Housing I is hydro and thermally insulated, due to which the heat losses of boiler 7 are used to heat the outside air, which improves the combustion of gas fuel and reduces heat loss. The flow limiter b ensures the constancy of natural traction and reduces fluctuations in traction, which stabilizes combustion.

The invention in comparison with the prototype and other known technical solutions has the following advantages:

-reduction of heat energy production;

-exclusion of the likelihood of a gas explosion and destruction of boiler houses due to the installation of the boiler outside buildings and structures; -exclusion of the use in heating systems of electric pumps and electrical equipment of instrumentation and automation; -increase the capacity of boilers by $ 15-20.
