Semicoke (garbage carbon), in carburization zone carbonization heat release, produces high-temperature flue gas and lime-ash.The heat energy of carbonization release is by accumulation of energy
Absorbed stores, and when adding house refuse in stove, the heat that domestic garbage pyrolysis is absorbed is by carburization zone and energy storage material
Material heat release provides, and the thermal discharge of carburization zone is more than the thermal desorption heat increasing upper rubbish, and pyrolytic reaction just can go on.Therefore
Need to ensure the carburizing temperature of carburization zone.At carburization zone equipped with temperature transmitter, by the temperature that records with analog quantity (0-24mA)
Signal is input in automatic control system microprocessor, is controlled the temperature of carburization zone by the analog quantity output signals of microprocessor

The side chain such as base, ethyl starts fracture, sloughs carbon and hydrogen respectively, generates the little molecules such as methane, hydrogen and other Hydrocarbon
Gas.Along with the further rising of temperature, the organic main chain taking off side chain ruptures, and generates many small-molecule substances.
The pyrolysis of rubbish is not necessarily to what certain order was carried out, and many reactions all intersections are carried out.Pyrolysis is produced little
Molecule is combined into the Organic substance of macromole again through condensation reaction, and the Organic substance of these macromole may also pass through cracking
Again become the Organic substance of little molecule, so the pyrolysis of rubbish is extremely complex physics, a chemical process.Fill at carburization zone
