Working principle and features of YONGLI boiler

  YONGLI manufacturing boiling furnace, the use of solid fuel in the furnace was flowing upward airflow hold, within a certain height range for rolling up and down movement, and fluidized (or boiling) state combustion chamber, also known as streaming fluidized bed combustion furnace.

     Fluidized bed combustion mode is also used in other kiln. Boiling combustion characteristics of solid fuel like that neither placed in a stationary layer burning furnace grate combustion; also not as liquid, gas, or ground into a fine powder in the combustion chamber of the furnace solid fuel suspended in furnace combustion space, but the solid fuel is broken into a certain size of the powder to make it in a similar boiling furnace combustion state. Its boiling furnace coal particle size is generally 8 mm.

     YONGLI boiling furnace design advantages are: not only can burn coal, low quality coal can burn all types of general grate furnace combustion chamber and can not burn.

Bed heat transfer pipe works well, it is about 5 to 10 times the normal boiler tubes. Since the fluidized bed combustion temperature is low, flue gas NOX generated less,as in the feed appropriate to add limestone or dolomite, coal sulfur can be removed, so that the content of the  flue gas SO2 decreased. Therefore, the boiling furnace structure has considerable advantages.
