Major Achievements of 2014

Through cold experiments and numerical simulation of supercritical CFB with annular furnace, the optimal furnace structure was determined; through hot experiments with semi-coke/coal in MW CFB platform, the characteristics of combustion and emission of pyrolysis of semi-coke were obtained; SO₂/NOx emission technology was proved in a 300t/h CFB boiler.

The 1MW CFB Oxy-fuel Combustion Pilot Plant was established and commissioned with a maximum thermal power of 1.2 MW and maximum oxygen concentration of 50%.

The first 40000 Nm³/h CFB coal gasifer of industrial fuel gas in China was put into commercial operation, which has been in operation for more than 1800 hours with low calorific values over 1450kcal/Nm³. This is the largest capacity in China at this point.

A 240t/d pulverized coal pyrolysis pilot plant with solid heat carrier was established, commissioned, and some experiments have been conducted, representing a breakthrough in the overall technological process.

Through a series of experiments in a 5t/d pilot platform, the combustion characteristics of residual carbon in CFB were obtained with combustion efficiency over 99%.

A 200kW hot experiment device capable of combusting pulverized coal with low volatile content was installed.
