ROTARY KILN INCINERATOR: JKA-230RK

Rotary kilns have become the backbone of many new industrial processes that make the world a more efficient and sustainable place. As new applications for rotary kilns continue to be developed, much experimental work is being done, prompting many questions and the need for further research and development. A rotary kiln is comprised of a rotating cylinder (called the drum), sized specifically to meet the temperature and retention time requirements of the material to be processed.

The kiln is set at a slight angle, in order to allow gravity to assist in moving material through the rotating cylinder. Rotary kilns can be either of the direct-fired type, or the indirect-fired type (sometimes referred to as a calciner). In a direct-fired kiln, a process gas is fed through the drum, processing the material via direct contact. In an indirectfired kiln, material is processed in an inert environment, and is heated through contact with the shell of the kiln, which is heated from the outside to maintain an inert environment.

Rotary Kiln is a pyro-processing device used to raise materials to a high temperature (calcinations) in a continuous process. The kiln is a cylindrical vessel, inclined slightly to the horizontal, which is rotated slowly about its axis. Some of the most common kiln applications in use:

  • Mineral Roasting
  • Proppant Sintering
  • Gypsum and Bauxite Calcining
  • Waste Incineration
  • Desorption of Soil Contaminants
  • Upgrading of Phosphate Ores
  • Waste Lime Recovery
  • Catalyst Activation
  • Activated Carbon Production & Re-Activation
  • Plastics Processing
  • Ceramics Processing

Product Description

Specifications:

  • Rotary Kiln (Rotataing Cylinder)
  • Combustion efficiency is at least 99%.
  • Combustion Chamber
  • Temperature of primary chamber is minimum of 800°C-1500°C and the secondary chamber is minimum 1200°C -1900°C.
  • The secondary chamber gas residence time at least two seconds.
  • Capacity: 500/1000/1500/2000 Kg/Hr.
  • Air Pollution control device
  • Wastes to be incinerated are not chemically treated with any chlorinated disinfectants.
  • Ash from incineration of waste is disposed of at common hazardous waste treatment and disposal facility. However, it may be disposed of in municipal landfill, if the toxic metals in incineration ash are within the regulatory quantities.
  • Power Requirement: LPG, N-Gas, Diesel, Electrical

Features:

  • To maintain designed heat capacity of the kiln, quantity of the solid waste injection package (kg/single injection) shall be adjusted w.r.t. calorific value of the waste feed.
  • When a high calorific value possessing solid waste is injected in packets, the size of each injection may be reduced, such that the peak CO concentration in the Kiln does not exceed too high in the initial stage, creating shooting of emissions to the secondary chamber, thereby crisis in ensuring the required retention time.
  • Appropriate slope (in general, 3 degrees), rotation rates and solid waste residence time (1-10 hrs) may be adjusted for the kilns, in order to achieve total organic carbon (TOC) and loss on ignition (LOI) requirements in the ash/slag.
  • To ensure life of refractory and insulation bricks, it is a practice to feed silica and glass in appropriate ratios to the kilns to form a cover over the refractory lining, as and when the thickness of the layer reduces.
  • It has been reported that reduction of out-side surface temperature of the rotary kiln enhances the life of refractory bricks and lining. Thus may be explored, where feasible.
  • In the rotary kiln, the temperature shall be maintained at 800+°C in order to ensure complete burning of solid waste. Controlled flow of air shall be maintained for complete volatilization of solid waste.
  • Ash removal doors are provided in the primary, secondary and settling chambers.
  • Temp. Indicator for Scrubber and stack ON/OFF switches, fuses, sensors, hooter etc. complete with in all respectfully lined with refractory materials and fitted with high quality packing to seal the door.
