Pyrothermogasogenerator allows to produce:

• charcoals and fuel coals;
• active charcoals and pit coals;
• carboniferous coke;
• gasification of low-carbonic and low-caloric types of fuel: peat, brown peat and other kinds of pit coals;
• converting wastes of woodworking, carbonic wastes of domestic and industrial origin, including slab, bark, branches, fillings, nut's shell, etc. into pyrocarbon (coal) and gaseous fuel;
• pyrolytic gas and heat which are used for different needs by means of heat exchangers or without them.

Environment is free of harmful blowouts!

1.1. Pyrolysis is a conversion of carbonic raw-materials under high temperatures and oxygen shortage.

1.2. Pyrolysis of carbonic raw-material is running at the pyrothermogasogenerator reactor under preset temperatures; and pyrocarbon (coal) of required quality as well as large quantity of heat and pyrolytic gas are generated depending on the selected condition.

1.3. Volatile components excreted in the course of pyrolysis, including water (H₂O) and other vapours, in the presence of carbon participating in the reaction as a catalyst, are converted to pyrolytic gas of different composition according to the formula:
C + H₂O + C_pH_xO_y = C_nH_m + CH₄ + H₂ + CO.
As the obtained gas passes through a sizable layer of the active carbon (coal), it becomes almost absolutely clear, free of any harmful impurities at the reactor outlet. Only carbonic-acid gas and water are blown-out into atmosphere in the time of complete combustion of such a gas.

2. Woody raw-materials

2.1. Mean heating value in common firewood burning down, e.g. birch, is 2 300 kCal/kg.

2.2. Mean volume of pyrolytic gas obtained from 1 kg of woody raw-material (firewood, fillings, substandard waste products, etc.) at the pyrothermogasogenerator totals 1,2 m³.

2.3. Composition of the pyrolytic gas obtained:

2.4. Specific weight of pyrolytic gas (at 0⁰C and P=760 mm Hg) is 0,65...0,85 kg/m³.

2.5. The lowest heating value of pyrolytic gas at 20⁰C and atmospheric pressure 760 mm Hg is 8 700...9 500 kCal/m³, i.e. 1 kg of woody raw-material processed in pyrothermogasogenerator produces at least 10 440 kCal/kg.

2.6. The pyrothermogasogenerator efficiency in pyrolysis of woody raw-materials to gas is 85% on the average. Thus, 1 kg of woody raw-material processed in this unit provides 8 874 kCal, what is 3,8 times greater than in common burning down of birch firewood.

2.7. The maximum flame temperature in burning down of pyrolytic gas in burners is 2 300⁰C.

2.8. Composition and main characteristics of the natural gas to be compared:

Specific weight - 0,47 kg/m³.
Lower heating value - 4 500 kCal/kg.
Maximum flame temperature - 2 200⁰C.

4.1. Conditions of charcoal and fuel coals production (GOST 7657-84; A, B, C marks).
One ton of the processed raw-material yields on the average 190 kg of charcoal and 810 kg of pyrolytic gas; 260 kg of pyrolytic gas is used to maintain the unit reaction, and 550 kg is used for different needs. Burning down this gas provides heat of up to 6 000 000 kCal.

4.2. Conditions of active coals production (GOST 6217-74, BAU marks and GOST 4453-74, OU marks).
One ton of the processed wooden raw-material yields on the average 60 kg of active coal and 940 kg of pyrolytic gas; 240 kg of pyrolytic gas is used to maintain the unit reaction, and 700 kg is used for consumers needs (up to 7 500 000 kCal).

4.3. Conditions of pyrolytic gas production.
One ton of the processed carbonic raw-material yields on the average 1000 kg of pyrolytic gas; 150 kg is used to maintain the unit reaction and 850 kg is used for consumers needs (up to 8 500 000 kCal).

4.4. All of the above-mentioned conditions are automated and adjusted according to the developed programs depending on the needed end-product required by a customer, according to both energetic and physicochemical and mechanical indices.

4.5. The pyrothermogasogenerator blows out on the average 4 times less CO₂ than while common burning down of initial raw-material as a fuel per power unit into atmosphere.

4.6. The pyrothermogasogenerator may operate together with any standart heat exchanger or a boiler.
