BLACKHOLE
incineration systems are controlled air and pyrolytic and are designed to
incinerate wide ranging hazardous solid and liquid wastes from industries, hospitals,
slaughter houses etc. For more information on the usage please refer Applications
section.
The equipment consists of two major components - Primary Combustion
Chamber (PCC) and Secondary Combustion
Chamber (SCC). Both the chambers are lined
with high temperature resistant castable refractory. Each chamber has got its
own respective burner.

In the PCC waste is fed and
gasified by partial combustion under sub-stoichiometric conditions, producing a
low-kcal gas, which then flows into the SCC, where it is combusted with excess
air. The secondary combustion produces high temperature (1000 to 1100˚C)
gases of complete combustion (CO2, H2O, and N2). Sufficient residence time is
provided for the gaseous materials to incinerate in the SCC. The temperature in
PCC is about 700 to 800˚C.
An ejector maintains a negative draft in the
incinerator and also dilutes the hot gases coming out from the SCC. A fume
scrubber & a quencher are provided where required to remove acid gas. To
recover the heat lost in ensuing hot gases from the secondary combustion chamber, a heat
recovery system can be provided to recover the heat in the form of hot water,
steam etc.
