Sanitary Napkin Incinerator (Version 4)
A novel incineration device has been developed that uses pyrolysis to decompose sanitary napkins into hydrocarbon vapours and combustible gases along with some non-combustible gases and char. These vapours and gases are made to pass over high temperature electric coils (>500 degC) where they auto-ignite in the presence of oxygen. The heat from the flames partially drives the pyrolysis of remaining sanitary pads. A smoke stack thermocouple sensor feeds back values to a PID controller implemented through a microcontroller to maintain proper pyrolysis and combustion conditions that result in a transparent flue gas exiting from the chimney.
