Waste Management goes beyond just collecting and disposing of waste. Hazardous waste generated by different industries and other facilities requires high temperature treatment. A rotary kiln incinerator can effectively treat different kinds of waste and ensure complete incineration. An Indian manufacturer of Rotary Kiln Incinerators, should be able to control process temperatures up to 1500-1800°C, have reduced emission of pollutants and meet the requirements of different industries.
The rotary kiln incinerator
A rotary kiln incinerator consists of a refractory lined cylinder which rotates about its axis. The waste to be treated is introduced into the kiln and is moved to the exit by the action of the rotating cylinder. Being rotated in its own axis, the waste is brought in contact with hospital incinerator walls of the kiln and oxygen present in the atmosphere and is heated and burned.
If required, the waste can be further agitated in the kiln by using multiple kiln arms in place of a single kiln arm. Depending on the configuration of the system and its auxiliary equipment, a rotary kiln can be used to treat a wide variety of waste, including liquid and sludgy wastes.
Versatility
An added advantage of a rotary kiln system is that it is designed to treat waste with different physical and chemical properties. These systems can be used to treat a variety of Industrial wastes and bio medical wastes. Medical waste requires special handling. Waste streams must be managed in a way that conforms with various biomedical and environmental regulations. Typically, medical waste requires special transportation and processing.
Incineration of Waste
Waste may be processed through a rotary kiln incinerator. The principles of operation for a rotary kiln incinerator are similar to those of a multiple hearth incinerator; however, a rotary kiln operates at much higher temperatures. If the rotary kiln is designed and operated properly, a significant reduction in the volume of the waste may be achieved as a result of the destruction of the organics.
Complete Combustion
Incomplete combustion of waste may be improved if the rotary kiln is designed with a secondary combustion chamber. The flue gas from the primary combustion chamber mixes with the waste in the secondary chamber and is further treated at elevated temperatures.
Process Control
The parameters of the process may be adjusted by the operator of the rotary kiln. Factors which may be adjusted include the speed of rotation, the temperature, the residence time of the waste within the kiln, and the air/gas flow to the waste.
Pollutant Control
Pollutants resulting from the combustion of the waste may be reduced by various after treatment controls integrated with the incinerator. The types and configuration of pollutant controls are based on the type and quantity of the waste processed and the standards established by local and/or national regulations. When considering Rotary Kiln Incinerator Manufacturer in India , buyers should evaluate the entire system.
Continuous Waste Management
Rotary kiln systems provide a number of advantages for design and construction of continuous waste processing systems. Strong and durable designs allow their use in a wide variety of facilities and industries. Periodic examinations of kiln components, as well as pollution control equipment, are necessary to operate the system safely and effectively.
Conclusions
Rotary kilns possess the potential to effectively incinerate a variety of wastes and to do so in a manner that minimizes the volume of waste handled by the facility. In addition, waste is completely mixed and vaporized prior to exit from the kiln. If employed in conjunction with appropriate controls, rotary kilns have the potential to provide healthcare and other facilities with the means to manage their waste more effectively.
