New technologies for the cement industry
By A Staff Reporter
The Government of India plans to study and possibly acquire new technologies from the cement industry of Japan. The government is discussing technology transfer in the field of energy conservation and environment protection to help improve efficiency of the Indian cement industry.
Under its Green Aid Plan, Japan's Ministry of Economy, Trade & Industry is providing assistance to a cement plant in India for implementing a project for power co-generation from waste heat for utilisation in the plant. Besides, the Japanese cement industry is using other superior technologies by utilising solid waste for producing eco-cement.
Kawasaki Heavy Industries, a leading manufacturer of high-performance cement plants, has supplied as many as 53 large-scale and energy-saving cement plants worldwide, including India. The company has produced various application plants such as limestone calcining system, fluidised bed limestone calcining system and fluidised bed coal moisture control system, while supplying cement plants.
New cement burning technique
FAKS or Fluidised Bed Advanced Cement Kiln System from KHIL is an innovative technology in cement burning, which is replacing the conventional rotary kiln system. Some of its features are:
* High flexibility in fuel choices: Various coals are available, from low calorific value to low volatile coal such as petroleum coke.
* Better thermal efficiency: 10-25 per cent reduction in heat consumption due to the configuration of the burning and cooling process by utilising the fluidised bed reactor.
* Low environmental impact: 10-25 per cent reduction in CO2 emission, 40 per cent or more reduction in NOx emission.
* Superior changeover productivity: Shorter changeover production time compared with conventional systems.
* Economical advantages: 10-30 per cent of construction cost saving and around 70 per cent reduction in installation space, lower maintenance and running cost compared with conventional system.
