SHXF series CFB boiler is a large capacity boiler, the new type boiler makes big breakthrough on the technology of cyclone fluid combustion, cyclone separation structure & parametric design, and loop seal device. 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.
Fuels:Lignite,Bituminous Coal,Lean Coal, Anthracite
Applications:Power Plant, central heating,chemical industry etc
Technical Advanatges:
1. Available to Burn Low Grade Fuel
Longer Fuel Combustion Period. Front arch is higher and shorter than rear arch, 45° angle between the two arches, which can extend the time of flue gas combustion time, and enhance thermal transferring efficiency. It also can burn low calorific value coal such as brown coal, lean coal, and semi coke.
2. Durable And Stable Grates
It adopts Global Environmental Facility special slag removal technology, and small flake gate, to overcome technical problem such as grate flakes falling off and air leakage, so that the grate can be operated stably and the combustion efficiency is greatly improved. The boiler grate adopts double layers or single layer layout structure, which can meet the customers requirements better.
3. 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.
4. 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.
5. 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.
6. Cyclone Combustion Technology
Arrange cyclone combustion device in furnace, achieves cyclone fluidized circulating combustion, improve combustion efficiency.
7. 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.
8. 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.
