Medical waste incinerator (click here) is mainly used for burning wastes produced by medical research facilities, veterinary facilities and hospitals. These wastes generally include both infectious medical wastes as well as non-infectious, general housekeeping wastes. Three types of incinerators are used for burning wastes: controlled air incinerators, excess air incinerators, and rotary kiln incinerators. Controlled air incinerators are dominantly used medical waste technology, and controls the market for new technology systems at numerous hospitals. This type of technology is also referred to as starved-air incineration or two-stage incineration.

Combustion of waste in controlled air incinerators takes place in two stages. In first stage, waste is injected into the primary combustion chamber, which is then operated with substantial amount of air required to carry out combustion process. Combustion air enters through the primary chamber from below the incinerator hearth. This air is known as primary air. Primary chamber, the low air fuel ratio facilitates the volatilization of the waste, and large percentage of the residual carbon in the ash burns.

In second stage, excess air is then added to volatile gases produced in the primary chamber to complete the combustion process. Secondary chamber temperature is generally higher than primary chamber temperature. Depending on the moisture content and heating value of the waste, extra amount of heat may be required. This can be achieved by auxiliary burners located at the entrance of the secondary chamber to maintain the desired temperature....
