Great technological breakthrough on the new type double whirlpool low speed circulating fluidized bed boiler

1.Breakthrough on separator structure design
Using the latest technology of double whirlpool separation structure by Tsinghua University. After separated in the second whirlpool, the material powder particles return to furnace for circulating combustion through the separate return system. The efficiency of separator increase to 10 μ particle cut size, improve the boiler’s combustion efficiency.

2.Breakthrough on separator’s parametrization design
Using the results of latest experiment, redesign the parameter of separator, optimize the line and size of whirlpool separator, the separate efficiency improved greatly.

3.Breakthrough on the technology of material back system
Using the hood ebullience fluidized integrate material back system, the situation of ebullience fluidized comes true. Manage the quantity of returned material by adjusting the height of fluidization, material return stably. Avoid difficult management of material back and the shortcoming of coking in material back system.

4.Breakthrough on the technology whirlpool fluidized combustion
Based on the distribution of fluidied material in furnace, swirl-burners are placed inside, they make the material vortex fluidized combustion circularly, and improve the combustion efficiency.

Thanks to the great breakthrough on the above technologies, the efficiency of new type double whirlpool low speed circulating fluidized bed boiler is significant, and it increases 2%~5%. The boiler technology is in the domestic leading position, and all technology parameters reach the domestic advanced level. The new boiler is listed as the Key Technology and R&D programme of State Education Commission, and the Project Promoted for National Science by the Ministry of Science and Technology.
