Concrete method of recovery of energy from renewable metal clothes
The reason for this is that (1) of toxic gases.
Polyvinyl chloride (PVC) combustion generated when oxygen chloride gas;
Polyurethane (pu) is burned to produce hydrogen cyanide gas.
Pure metal coat hooks need plenty of air when waste burning, for the urban garbage burning air demand ~ times, to achieve complete combustion, ordinary incinerator can't satisfy this requirement, therefore, waste metal clothes hook will burn and produce smoke from lack of oxygen.
Polyvinyl chloride (PVC) metal clothes generally contain lead salt and other heavy metal salt stabilizers, heavy metals such as lead in ash after combustion is difficult to deal with.
(4) water acidification.
Polyvinyl chloride (PVC) combustion to produce hydrogen chloride gas is absorbed by water or chemicals, formation of acidic water is difficult to remove.
(5) high combustion temperature.
Scrap metal coat hooks than those produced by the burning of municipal waste combustion temperature is much higher, normal incinerator unbearable, furnace high temperature caused damage.
6. Corrosive materials.
Scrap metal clothes combustion can be induced in hydrochloric acid, ammonia, sulfur dioxide, sulfur trioxide, NOX and RCOOH corrosive substance, such as corrosion damage in furnace, more will accelerate the corrosion of the gas in the waste water.
In a word, for the pure metal coat hooks of waste incineration needs specially designed incinerator.
