Bio Medical Waste Incinerator

The Bio Medical Waste Incinerator and Medical waste incinerator is one of the treatment and safe disposal of the bio medical waste generated from the hospitals, veterinary facilities, medical research facilities etc.

These wastes include both infectious medical wastes as well as non infectious, general housekeeping wastes. Bio medical incinerator is equipped with necessary air pollution control devices APCD for removal of pollutants from flue gases to achieve desired level. The flue gases are cleaned for removal of pollutants and gaseous compounds by passing through various air pollution control devices APCD before releasing them into the atmosphere through stacks filter are provided to make incinerator complete pollution free, smoke, colorless Treated, odorless treated.

Following design criteria adopted for better performance. The bio medical waste incineration is designed for primary and secondary combustion systems. Total Organic carbon content in the slag/bottom ash is less than 1 percent or their loss on ignition is less than 3 percent of the dry weight as prescribed. The double chamber incinerator is preferably be designed on controlled air incineration principle, as particulate matter emission is low in such incinerator. Air supply in the primary and secondary Chamber may be regulated between 30 percent to 80 percent and 170 percent to 120 percent of stiochiometric requirement respectively.

In primary chamber, primary air is admitted near. Suitable flow measurement device is provided on the primary and secondary air ducting. The combustion air is supplied through a separate forced draft fan after accounting for the air supplied through burners. The primary chamber is to avoid leakage of gaseous emissions from the chamber and for safety reasons.

The secondary chamber is properly designed so as to facilitate a minimum of two seconds residence time to ensure combustion of the gas flow, unburnt material such as volatiles, smoke and soot. For the estimation of residence time in the secondary chamber its volume calculated starting from the secondary burner tip to the thermocouple. Incinerator walls are protected with insulated fire bricks or refractory system. The refractory lining of the chamber is strong enough to sustain thermal shocks i.e. minimum temperature 1000C in the primary chamber and upto 1450C in the secondary chamber. The refractory and insulation brick is have suitable thickness.
