the Heating equipment: teplogeneratory and coppers (ch. 3)

Distinctive feature of the device is warmth redistribution between systems of heating and hot water supply . Depending on increase in one of functional loadings, the heat-carrier can dogrevatsja to more heats at the expense of return of warmth by the heat-carrier of other system. Warmth redistribution is carried out through four skoboobraznye a pipe and the adjacent cylindrical surface washed by heat-carriers of both systems.

Water of system of heating heats up to settlement parametres at the expense of warmth transfer through surfaces and from located in the heating heat exchanger dymogarnoj pipes on which take place smoke gases from a fire chamber.

the Design of the top internal device allows to burn firm fuel in the thick layer providing single loading about 30 kg of fuel at 6-8 o'clock of continuous work.

Primary air on burning arrives under a grid-iron lattice, through zhaljuzijnye door apertures zolnika. Secondary air for reburning of flying substances moves in nadslojnoe space through furmy with adjustable section.

On the basis of device ATV-17,5 has been created dvuhfunktsnonalnyj teplogenerator АТВ-23,2 (model 3107) (fig. 18), working in a mode of long burning. The device has the loading bunker and an inclined grid-iron lattice. Fuel submit through the loading bunker from which under the influence of a body weight fuel arrives on an inclined part of a grid-iron lattice. The thickness of a layer of fuel is regulated zaslonkoj.

The bunker Volume is calculated on a stock to 45 kg of coal that allows to maintain the device without dozagruzki in a current of days (tab. 15).

the Two-functional device heating with hot water supply on fire wood and torfobriketah АТВ-23,2 (model 3131) is intended for the centralised heating and hot water supply of individual apartment houses by the area of 100-150 m 2 (tab. 16).

the device Design is executed in the form of a squared shape curbstone. In devices there is a bunker for fire wood, a fire chamber with vertical and horizontal grid-irons, pig-iron screens, a contour of water heating, capacity for hot water supply, gazohody (fig. 19).

Distinctive feature of the device is presence of the fire chamber which are ensuring functioning of the device within not less than 8 hours from one loading, and application of pig-iron screens for the best reburning of flying substances.

Fuel on a grid-iron burns with orientation of a torch towards a pendant vertical grid-iron lattice. For fuller combustion in a burning zone through the device secondary air moves. Smoke gases through gazohody rise upwards, through a backlash in the top part of a fire chamber fall to the bottom part gazohoda and get in dymogarnuju a pipe, heating up on the way pendant vertical screens and the heat-carrier in teploobmennoj capacities. Nagretye pendant vertical screens accumulate warmth and promote the further reburning of flying substances.

Thanks to presence of adjacent walls of heat exchangers of heating and hot water supply redistribution of warmth depending on teplopotreblenija is provided.

In the tank centre the pipe with the extension piece is located teploobmennaja. The space between the tank and a casing is filled by isolation from shlako - or glass wool. Over an exhaust outlet zharovoj pipes it is located tjagopreryvatel. In the bottom part of the device the injection torch of low pressure in which on an arm fastens zapalnik is placed. Zapalnik has two uvulas of a flame: from one there is an ignition of the basic torch, from the second heats up spaj thermocouples.

the torch Amalgamator represents bent at an angle 90 ° profilirovannuju a pipe. On diffuzore the amalgamator there is a pig-iron nozzle. Fire apertures in a nozzle are drilled in the special inflow located in one number that improves conditions of a supply of secondary air to torches. As the torch works with factor of surplus of air and < 1, this condition is necessary. The arrangement of apertures on a circle promotes uniform distribution of warmth in shonke, and the great number of apertures allows to receive torches of the greatest height.
