Rotary Kiln
A new giant petrochemical processing complex in China required an incineration system to reduce the volume of wastes transferred to off site disposal.
Verantis was able to design and supply a complete incineration system with waste heat recovery, air pollution control equipment and feed systems that met regulatory requirements.
The combustion system uses a rotary kiln for primary combustion of shredded solid waste, dewatered sludge, and liquid waste and a secondary combustor for holding the products of combustion at 1,000 degrees C for two seconds. The kiln is equipped with a dual fired burner to burn low sulfur fuel oil and/or energetic liquid waste. The secondary combustion chamber (SCC) is equipped with an emergency bypass stack and stack cap, designed to open on power failure or positive pressure. A dry type water cooled ash drag conveyor is installed under the SCC for bottom ash removal. The rotary kiln installed has an overall length of 13.7 meters from feed to discharge and has an internal diameter of 3,454 mm.
Kiln shell is made of boiler plate steel and is lined with stalastic liner for corrosion protection. Kiln refractory is designed for a continuous operating temperature limit of 1,550°C. The kiln is tapered from the feed end and is designed with a 2 degree slope from horizontal.
Overview
Verantis designed an supplied a system to treat solid wastes, aqueous liquids and sludge using incineration to reduce
the volume of wastes transferred to off site disposal.
Equipment
Verantis designed and supplied all equipment for a complete incineration system with waste heat recovery and air pollution control and feed systems.
Auxiliary Equipment
Verantis also supplied a complete sludge dewatering plant using belt filter presses. The dewatered sludge is fed by progressive cavity pumps to a sludge storage and a double acting hydraulic pump. Solid waste is shredded in a hydraulic shredder and fed to the kiln with a belt conveyor and a sequential ram feeder.
Technical Capabilities
All parts of incineration and air pollution control systems are designed in-house. System components are sourced through a world-wide network of fabricators and suppliers.
Design Capabilities
Systems can be designed to accommodate a variety of requirements including NFPA and other regulatory codes such as Chinese GB, European EN and US EPA standards.
