  • the heater is further characterized in that the replaceable cartridge is equipped with a catalyst for the purification of flue gases.
  • the heater is yet further characterised in that the air supply unit comprises a control unit in a form of a mechanical lever with a rod and an adjusting screw interacting with a air flap.
  • the heater comprises a combustion chamber 1 in a form of a vertically oriented cylinder or polyhedron.
  • the chamber 1 has a double wall, thus forming a cavity 2 for heat-transfer agent, and an outer wall 3 with thermal insulation shielded with a metal sheet.
  • Inside the heater there is a air heating chamber 4 connected with a telescopic pipe or metal bellow 5 with a air distributor 6 fixed to its end.
  • the chamber 4 is connected to the pipe 7 for air supply from the underneath.
  • the upper part of the heater is equipped with a chimney having a replaceable catalytic cartridge 8, and the external part of the heater comprises the heat-transfer agent return pipe 9 which goes from the adjustable three-way valve 10.
  • the chamber 4 of the heater is equipped with a flap 11 for switching the direction of air flow through the pipe 7.
  • the lower part of the heater is equipped with a grating 12.
  • the output of the heat-transfer agent from the heater is performed through a nipple 13, and the input of the heat-transfer agent to the heater is performed through a nipple 14.
  • the heater is equipped with an electric air valve 15 by means of which is controlled the volume of air supplied to the heater.
  • the air is fed by a pneumatic pump or fan 16 which is controlled by a thermostat sensor 17.
  • the wall of the heater comprises an opening 18 with a thermometer incorporated therein.
  • the heater has two openings in its wall with sealable doors 19 and 20 for fuel loading and for ash removal, respectively.
  • the heater is equipped with a cable 21, a part of the cable is outside the housing, another end of the cable is connected to the telescopic pipe or metal bellow 6.
  • the cable 21 is fixed to the wall of the heater by a hook 22.
  • the heater is loaded with any type of fuel 23.
  • the air distributor 6 comprises a cone shaped tip 24 with the air supply channel 25, with the hollow metal disk 26 mounted over so as to obtain an open annular space in the form of an annular gap between the disc 26 and the inner wall of the combustion chamber 1. Said annular gap makes 20-30% of the cross sectional area of the chamber 1.
  • the hollow disc 26 has openings 27 in the form of nozzles for distribution of the air: about 40% through the tip 24 and about 60% through the nozzles 27.
  • the distributor 6 has support legs 28 for the placement onto the fuel 23 with some clearance.
  • the housing of the replaceable catalytic cartridge 29 has a multichannel porous catalyst 30, the channels are made of metal or ceramic, arranged along the housing 29 and covered with the chemical composition acting as a catalyst, preferably Palladium or analogues, for the combustion products.
  • a thermo-independent rod 32 is connected to a housing of the heater by means of a bolt 31 and is further connected from the underneath to a flat lever of the mechanical air flap 33, from the above the lever is pinned down by an adjusting screw 34 inserted into the support elbow 35.
  • Operation of the heater is implemented as follows.
  • the fuel 23 is loaded into the chamber 1 through the door 19; a kindling material is placed on top and set on fire.
  • a ring of a metal cable 21 is removed from the hook 22 and lifted up; as a result, the air distributor 6 goes down on the fuel 23.
  • the door 19 is tightly closed.
  • the fan 16 is turned on, and the air is fed through an electrical air valve 15 and mechanical air flap 33 to the heating chamber 4. From the heating chamber 4 the air is distributed into two flows: the upper and lower in the following proportions: 30 - 40% through the air distributor 6, and 60 - 70% through the pipe 7.
  • the air heated in the chamber 4 goes down the telescopic pipe or metal bellow towards the distributor 6, providing the combustion area with oxygen from the above.
  • the air distributor 6 descends on the telescopic pipe or metal bellow due to burning-out of the fuel 23, ensuring the combustion only in the upper area.
  • the output of the combustion products occurs through the chimney with a catalytic cartridge 8.
  • the heat thus produced contributes to further process of oxidation and purification of the products of combustion emitted during the operation of the heater, in this way improving the environmental safety of the heater.
  • the heat-transfer agent supply nipple 13 is equipped with a temperature-controlled three-way valve 10, which serves to ensure rapid heating and stable operation of the heater.
  • the valve 10 directs the flow of the heat-transfer agent through the recirculation pipe 9.
  • the valve 10 gradually starts forwarding the heated heat-transfer agent to the heating supply system, thus the heater operates stably and economically.
  • the thermostat disconnects the fan 17 and the electric air valve 15 closes the access of air into the cavity of the heater.
  • the heater is equipped with a mechanical air flap 33.
  • a metal housing of the heater expands when heated under the physical properties of the metal, a part of the heater located above the bolt 31 stretches upwards, and a thermo-independent rod 32 remains in the same position.
  • the pressure from the rod 32 onto the lever of the mechanical air flap 33 weakens and the flap 33 descends, cutting off the air flow into the heater.
  • the travel range of a lever of the mechanical flap 33 is regulated by a screw 34. In this way the heater can control the operating temperature without power supply, what significantly enhances its application and safety.
  • the heating system operates stably, and in the event of the drop of heat-transfer agent temperature, the operation process of the heater is reactivated as described above.
