In a General sense the impact of the cost of fuel, boiler or other equipment, its technical and operational characteristics are direct factors in the cost of generated heat or cold. The choice of technological schemes of work equipment and, in particular, such a working agent, as atmospheric air as a coolant, serves as a cofactor in the reduction of cost, as it has several advantages over such fluids as water, antifreeze, etc. the main advantages of using air as a coolant is a simplification of the technological scheme of the organization of heating systems using devices heated floor, followed by the distribution of air through the injection device in the heated premises.

In view of the foregoing it would be desirable to have an installation that did not claim to be the highest requirements for solid fuel, except as restricted by moisture, provided the combustion efficiency. In addition, it would be desirable to have such a device, which in addition to their other characteristics would be able to produce cold, for example in the summer.

The claimed methods and installation provide significant advantages over known.

First, allow use of inexpensive low-grade solid fuel, and in addition to that what about that the use of air as a heat carrier makes possible more efficient use of for heating the heated space and the formation of the required environment. Secondly, due to more flexible use of the boiler furnace and placing within it a water or dry ice, fresh air can be cooled and refrigerated to be manipulated by the user.

From the camera 10, the coolant enters into the exhaust pipe 12 and the recirculation pipe 22, in which is placed the humidifier 14 in the air Elevator 16 in which there is a mixture of fresh cold air from the heated and humidified air recirculation pipeline 22. Of the humidifier 14, the cavity of the furnace 9 and ash pan 7 moisture is removed through the drainage device removal of excess moisture 17, 18, 19, and the coolant circulates in the side of the display systems with the speed of 10-25 m/s, in the radiation tube 6, the air flow speed is 15-40 m/s. Placed inside the tube 6 spiral swirl 20 at such flow rates without the ha forms a tangential component of the flow velocity, which affects thermal resistance of the boundary layer, which leads to an increase of heat removal from the inner surface of the radiation tube 6, thereby reducing the temperature of the pipe wall 6, and with it the temperature within the furnace volume of the installation to the temperature at which it is optimal pyrolysis of solid fuels.

Achieved by the invention the technical result is to increase the heat removal per unit area of the heating of the display surface due to the intensification of heat transfer, gasification of the solid fuel and efficient combustion in the furnace. The coolant after passing through the humidification and heating in a temperature range of outdoor air has parameters close to those that can be obtained in air conditioning systems and which are necessary for the formation of a microclimate in a heated room in winter and summer seasons.

Pipe 6 is welded to the precast upper manifold 11 of the air distribution chamber 10, from which extends a pipe feeding the coolant to the heat consumer and recirculation pipe of the coolant. This line set the humidifier 14 air, after which the heated air picking up moisture, reduces its temperature without reducing the heat content, served in the air Elevator 16 pipeline supply air, which air is supplied in two side of the screen 3 cooling of the walls of the furnace 4. This method involves creating the necessary temperature conditions under which the possible maximum volatile combustible gases from solid fuels, and differs in that the combustion IP is alzueta heated humidified air, used from the recirculation pipe 22 after the humidifier 14.

According to scheme 3, the cooling air takes place on the same principles as the heating agent, but instead of heating in the furnace installation of the radiant tubes are placed dry ice or pieces of ice nevrogennogo in the winter of fresh water in the bottom of the ash pan 7 has a water drainage 18, formed from the melting ice to drain into the sewer 19.

The first stage of the working agent is in the line after launching into the combustion mode installation, air Elevator 16, in which fresh air is mixed with the recirculation of the heated coolant.

The second stage of heating occurs in the side screens 3 on the outline presented in Figure 3.

The moisture contained in the solid fuel, up to a certain limit has a positive effect on the pyrolysis of solid fuels occurring in the furnace 9. Thus, by increasing the efficiency of heat exchange is realized a significant reduction in fuel consumption due to efficient combustion in the furnace. Further in accordance with the invention for the intensification of heat transfer is affected by the humidifier 14 for humidifying air, which can increase the moisture content in the air at negative ambient temperatures from one gram in one cubic meter of air to 14-18 grams for every 1,000 cubic meters of fresh air to spray up to 16-18 kg of water in the form of aerosols to get comfortable conditions inside the heated premises, provided that this air will be used as a source of fresh air supply ventilation system. Water for humidification is supplied from the water supply through pipeline 21 to the humidifier 14.
