The new type double whirlpool circulating fluid bed boiler with low speed is a new generation CFB boiler. It is consist of combustion chamber, separator, fly ash circulating system, superheater, convection bank, economizer, and air preheater. The boiler inherits the original technology advantages, at the same time, makes big breakthrough on the technology of cyclone fluid combustion, cyclone separation structure & parametric design, and loop seal device. The thermal efficiency is about 5% higher than the other CFB boilers.
Technical Advantages
1. Double Cyclone Separator
After separated by the second cyclone, the fuel powder particles return to furnace for circulating combustion through the separate loop seal. The diameter of particles could be cut into 10μ by separator, improve the combustion efficiency.
2. Parametrization Design on Separator
Using the results of latest experiment, redesign the parameter of separator, optimize the line and size of cyclone separator, the separate efficiency improved greatly.
3. Bubbling Fluid Loop Seal Technology
Using the hood bubbling fluid integrate loop seal device, achieve the situation of bubbling fluid. It has the advantages of material feed steadily, convenient control, and avoid coking.
4. Cyclone Combustion Technology
Arrange cyclone combustion device in furnace, achieves cyclone fluidized circulating combustion, improve combustion efficiency.
5. Membrane water wall
The furnace, separator and loop seal device adopts membrane water wall, prevents the low efficiency caused by air leakage, low heat loss.
6. Anti wear design
The buried pipe adopts anti-wear steel with the special size and angle, and reduce the fluidization velocity, to reduce the wear. The high temperature resistant material is deposited on the water cooling wall of the separator, avoiding the abrasion of membrane wall.
7. Environment Protection
The product uses low-temperature combustion technology, reduce the generation of noxious gas, also, the limestone could be added to the furnace for desulfuration, meet the requirement of environmental protection.
