Plasma Ignition and Combustion Stabilization (PICS) Technology for Pulverized Coal Fired Boilers
PICS is a technology that can largely or totally reduce fuel oil consumption during boilers operations such as startup, shutdown, low load regulating operations. It can directly ignites pulverized coal with plasma arc at the initial stage of pulverized coal entering the burner when there is no flame in the furnace so as to realize oil-free start-up and oil-free combustion stabilization at low load.
PICS was first successfully put into commercial application in year 2000. After 25 years of development, it has now become a very mature technology, bringing significant economic benefits to customers.
Up to April, 2024, PICS has been applied on 1042 projects (1012 nos in China mainland and 31 nos in overseas). -
Mini Oil Ignition & Combustion Stabilization System
Mini-oil Ignition technology combines medium atomization and intensified gasification, applying the stable and high temperature (above 1800℃) oil torch with a small amount of fuel oil (20-250kg/h). When pulverized coal goes through the oil flame, it will soon absorb the heat and release volatile matters which immediately burst the coal particles and ignite. With staging combustion and unique air distribution, sufficient combustion can be realized at the beginning of ignition and the afterwards burning condition would be more stable.

Fuel Oil Free Power Plant
Dependent on plasma ignition and combustion stabilization system, LY Power developed Fuel Oil-free Power Plant firstly in world. It means all those oil facilities including oil guns, oil pumps, oil pipes, oil tanks, etc will not be required at all for these pulverized coal fired power units. After the application of PICS Oil-free Technology, the power plant will eliminate fuel oil completely. In May of 2008, LY Power completed the first demonstration PICS fuel oil-free project. By the end of 203 LY Power has applied PICS Oil-free Technology on around 170 oil-free power units of 70 power plants.
