Pulverized Coal Injection (PCI) using the dense-flow method. The Küttner developed and perfected dense-flow method offers several advantages over a lower-density system. Higher injection rates are achieved with simultaneously lower coke rates, which can optimize the fuel costs of the blast furnace.
The technology burns coal at temperatures below the threshold that is needed to form nitrous oxide (NOx) pollutants. NOx is produced when coal is burned at high temperatures as is typically seen in traditional pulverized coal boilers. By burning fuel at lower temperature, any emission from the CFB boilers is greatly minimized.

A 2000 MW power station could be handling coal in the range of 1600 tons/hr or around 12 million tons of coal annually. A single 500 MW unit consumes in the range of 400 tons/hr of coal. The coal input to the boiler of the power plant passes through three different phases before combustion in the boiler.
1. The power consumption of raw coal pulverizing system is high, leading to high operating costs. 2. The fineness of pulverized coal produced by current grinding equipment is poor, and the combustion efficiency is low. 3. The productive technology of original equipment is backward, the efficiency is low and the wear-out is serious.
