Definitions
- the utility model relates to heat power engineering, in particular to heating devices, in which solid fuel of plant origin (firewood, wood waste, chips, straw) is subjected to high-temperature gasification (pyrolysis) followed by combustion of pyrolysis gases and coal residue.
- solid fuel of plant origin firewood, wood waste, chips, straw
- pyrolysis high-temperature gasification
- the prior art describes a heating device (boiler), which comprises a wood fuel hopper, a gasification chamber (primary combustion chamber) and an afterburner consisting of one or two compartments located below or to the side of the gasification chamber (primary combustion chamber), placed in a single vertically oriented housing.
- a heating device which comprises a wood fuel hopper, a gasification chamber (primary combustion chamber) and an afterburner consisting of one or two compartments located below or to the side of the gasification chamber (primary combustion chamber), placed in a single vertically oriented housing.
- the majority of commercially available wood fuel boilers are made according to this scheme, for example, products manufactured by ARCA, Astra, Atmos, Attack, Buderus, Cichewic, Guntamatic, Kalvis, Schutechnik, Kostrzewa, Orlan, Solarbayer, Viessmann.
- the prior art describes several technical solutions that allow using wood with high moisture content as fuel for a household heating device of small power (20-100 kW).
- the fundamental basis of the technical solution is to create and maintain a high temperature (700-800 °C or more) in the gasification chamber (primary combustion chamber) at which water vapor in contact with hot coal turns into two combustible gases: hydrogen and carbon monoxide.
- the pyrolysis gas afterburner is placed inside the gasification chamber (see EP 2 821 698 A1 ), or the pyrolysis gas afterburner is made in the form of a ring concentrically surrounding the gasification chamber (see DE 3411822 A1 and RU 2578550 C1 ), or a stream of hot combustion products leaving the pyrolysis gas afterburner rises and at the same time washes and heats the side walls of the gasification chamber (see CZ 2008191 A3 ).
- the prior art also describes a heating device in which the above-mentioned heating methods are supplemented by blowing very hot primary air into the gasification chamber at high speed (see RU 164691 U1 ).
- a permanent design flaw is that small doses of wood pyrolysis products, including carbon monoxide, which are inevitably present in a mixture with water vapor, are also emitted into the atmosphere. In the 30-40s this did not hold any significance, but since then, the requirements for the ecological cleanliness of heating devices have been significantly stricter. So, the Soviet standard from the 80s for wood stoves (GOST 9817-82) limited the permissible carbon monoxide emissions to 4%, but the modern European standard EN 303-5 for class 5 requires a reduction in carbon monoxide emissions to 0.04%. It is not always possible to reduce carbon monoxide emissions to such a level even with the use of complex after-combustion chambers; all the more it is impossible to meet the strict modern standards by discharging the contents of the gas environment of the fuel hopper directly into the atmosphere.
- the technical result for achieving the claimed utility model is the sustainable and environmentally friendly burning of wood fuel with a natural (i.e. high) moisture content.
- a heating device using wood fuel comprising placed in a single vertically oriented housing a hopper for solid fuel and a gasification chamber below it, an afterburner, as well as primary and secondary air supply ducts, an exhaust chimney and a water tank, inside which a fire tube heat exchanger is placed, which has at least one vertically oriented additional gas duct, the upper opening of which is located at the upper point of the internal volume of the fuel hopper, and the lower opening is located in the area of the afterburner, where the combustion of the flame ends.
- At least one gas collection funnel can be installed in the upper part of the fuel hopper, the upper point of which is connected to the upper opening of the additional gas duct.
- a shut-off and control valve may be inserted into the additional duct.
- the additional gas duct can be at least partially placed inside the water tank, while a container for collecting condensate with a device for draining condensate out of the heating device is placed at the bottom of the part of the additional gas duct that is placed in water.
- the claimed device can be manufactured with standard equipment using known and traditional heating devices, technological processes and materials.
- the claimed utility model meets the criterion of industrial applicability.
- FIG. 1 shows a vertical section of the version having a gas collection funnel but no condensate collecting tank.
- the heating device comprises a solid fuel hopper 1 with a loading hatch 12, gasification zone (chamber) 2 located in the lower part of the hopper, afterburner 3, primary air supply ducts 4, secondary air supply ducts 5, water tank 6 housing a fire-tube heat exchanger 7 connected to the smoke exhauster 8 via the outlet chimney.
- the heating device operates as follows. Wood fuel 11 (for example, firewood or wood chips with a natural moisture content) is loaded into the hopper 1 through the loading hatch 12 on the side wall of the hopper. Due to gravity, the wood fuel falls down, successively passing through the drying zone (upper part of the hopper), the dry distillation zone (lower part of the hopper) and enters the gasification zone (chamber) 2. In this zone, the fuel is ignited from an external source (not shown) and burns in the atmosphere of primary air supplied to the gasification and primary combustion zones through duct 4.
- Wood fuel 11 for example, firewood or wood chips with a natural moisture content
- Combustible gases (hydrogen, methane, carbon monoxide), formed as a result of primary pyrolysis of wood and chemical reduction after contact with hot coal, enter the afterburner 3, where they are mixed with secondary air entering through duct 5 and burned in the flame 13.
- the hot combustion products from the afterburner enter the fire tube 7, where they transfer their heat to the water in tank 6 and are then discharged into the exhaust pipe with a smoke exhauster 8 , from there into the chimney (not shown) and then to the atmosphere.
- the movement of water vapor from the top of the additional gas duct 9 to the bottom occurs under the influence of rarefaction (differential pressure) created by the smoke exhauster 8 in the afterburner 3; furthermore, the difference in the specific gravity of the steam having a temperature of 100-120 °C and the combustion products in the afterburner having a temperature of more than 800-900 °C contributes to the movement of steam from the top of the additional gas duct 9 to the bottom.
- the removal of or at least a significant reduction in the amount of water vapor in the primary combustion zone contributes to the sustainable burning of wood fuel.
