Liquid Injection Incinerators are highly popular
systems used to convert the hazardous waste materials to safe compounds,
imparting proper disposal of both hazardous and non-hazardous wastes.
These wastes are easily disposed by implementing several processes i.e
drying, solidification, vitrification and then concentration. To allow
for easy combustion, these system utilize high pressure to prepare
liquid wastes for incineration by breaking them up into tiny droplets.
In incineration process, waste is pumped and sprayed into the combustion
chamber. Highly sensitive to waste composition and flow changes, these
incinerators are single chamber units consisted with waste burners. Also
regarded as versatile thermal units, they are highly used to dispose
pumpable organic liquid wastes.
Features
Available in both horizontal and vertical configurations, liquid
injection incinerators can completely combust noncombustibles like
contaminated water, along with organic combustible material. The wastes
produced from incinerators are atomized into small droplets to allow for
the greatest possible mixing with air. Easy to install and operate, they
are comprised with flow meter, combustion chamber, powerful burner
nozzle etc. used for the atomization of aqueous and non aqueous wastes.
Principle
Through waste burner nozzle, liquid wastes are fed into the combustion
chamber where waste is atomized and mixed with the air. After mixing,
mixture is ignited and ignition burned in the combustion chamber. The
operating temperature of the combustion chamber varies from 1,300°F
to 3,000°F. Sometimes, when the energy content is not
adequate to maintain the ignition and incineration temperature, natural
gas or fuel oil is pumped into the combustion chamber from a storage
tank to improve the ignition potential of the waste mix. This system is
available with a fan which is essential and necessary required for
combustion.
Remember
Impaction or Impingement of flames on the wall of the combustion
chamber should not be allowed as it can lead to corrosion of the
refractory material and loss of heat. Due to this location of the
burner should be an important design criterion. Sometimes
oxygenenhanced burners can also be used by liquid injection
incinerators

Applications
Liquid Injection Incinerators are highly used in varied
applications such as:
- To destroy and burn hazardous wastes.
- To damage sludge, slurry, vapor and combustible liquids.
- To dispose several aqueous and non aqueous wastes that can be
atomized.
- It consist of powerful burner nozzle that is used for atomization
of aqueous and non aqueous wastes.
- High temperature is generated by these incinerators, widely
applied for an effective treatment for wastes containing chlorinated
hydrocarbons and sulfur compounds.
