Description

Utility model A thermal unit for drying antlers containing a firebox with a gas duct located in a cooled casing, a transverse partition with secondary gas afterburning nozzles is installed in the firebox, forming a compartment connected to the chimney with a rear end wall, with holes for supplying cold atmospheric air, and in its upper part - exhaust pipes for heated air, characterized in that sand containers are placed on the sides, top and rear wall, and on the side walls between tyami sand has square tubes of different lengths, the height, the sectional area of the lower parts of the upper 2/3 larger. EFFECT: invention makes it possible to increase profitability when burning solid fuel in furnaces of thermal units and drying of antlers. 3 ill.

The utility model relates to a power system and can be used to obtain high potential heat when burning various types of solid fuel in the furnaces of thermal units.

Known heating and cooking stove for solid fuel, adopted as a prototype, containing a furnace with a flue located in a cooled casing (see RF patent No. 198059, IPC F24B 1/02, 08/15/1994).

A disadvantage of the known heating and cooking furnace is its low profitability due to the impossibility of obtaining high potential heat when burning solid fuel, while ensuring simultaneous heating of atmospheric air in different layers.

The objective of this utility model is to increase the efficiency when burning solid fuel in the furnaces of thermal units, to preserve heat after the end of the furnace.

The problem is solved in that in the thermal unit for drying antlers, which contains a firebox with a gas duct located in a cooled casing, a transverse partition with secondary gas afterburning nozzles is installed in the firebox, forming a compartment connected to the chimney with a rear end wall, and in its lower part openings are made for supplying cold atmospheric air, and in its upper part there are exhaust pipes for heated air, and sand containers are placed on the sides, top and rear wall, while on the side walls between the sand containers are placed square pipes of various lengths in height, while the cross-sectional area of their lower parts is 2/3 larger than the upper ones.

In FIG. 1 shows the proposed thermal unit, front view.

In FIG. 2 is a side view of FIG. 1. In FIG. 3 is a section along AA of FIG. one.

The thermal unit for drying antlers, contains a furnace 1, placed in a cooled casing 2, consisting of rectangular pipes 3 and sand containers 4, a furnace 5 with an air supply regulator 6. The furnace 5 is hermetically closed by a door 7, and In addition, it has a transverse partition 8 with nozzles 9 for afterburning of secondary gases. The partition 8 forms, with the rear wall 10 of the stove 1, a compartment 11 connected to the chimney 12 with a gasifier-regulator 13. This arrangement of the partition 8 makes it possible to catch the heat leaving the combustion products, which increases the efficiency of the unit. In the lower part of the casing 2, holes 14 are made for supplying cold atmospheric air, and in its upper part there are outlet openings 15 for heated air.

The proposed thermal unit operates as follows.

When solid fuel is burned in the furnace 1, which is located in the furnace 5 with air regulation 6 and the door 7 is closed, the casing 2 with pipes 3, containers with sand 4 is heated, and high-temperature combustion products are formed. Through the openings 14 in the lower part of the casing 2, cold atmospheric air is sucked in, which, flowing around the firebox 5, is heated and exits hot through the openings 15. This is due to the difference in densities of cold and hot air. In this case, sand is heated in containers 4, through the rear wall 10 and the top of furnace 1. Smoke from furnace 1 passes through a pipe 12 with a gasifier-regulator 13. The resulting hot air coming out of pipes of different heights 3 is used to dry antlers placed on shelves. The resulting combustion products, getting into the upper part of the furnace 5 and passing over the partition 8, come into contact with the nozzles 9 are burned in the compartment 11. During the operation of the thermal unit, the sand in the tanks 4 heats up, accumulating heat, and after burning in the furnace 1, the heat continues to dry the antlers deer on the shelves.

Thus, efficiency can be improved when burning solid fuel in the furnaces of thermal units and drying deer antlers.
