Coal-fired SGS Standard Circulating Fluidized Bed Boiler for Power Plant
☞CFB Boiler Product Introduction
☞CFB Boiler Technical Features
1. Focus on solving the problem of heating surface wear. Select a reasonable flue gas flow rate and take effective measures for wear preventionto reduce wear of heating surfaces.
2. Select a reasonable separator inlet flue gas velocity and ascending velocity to reduce separator wear and improve separation eficiency of theseparator.
3. Optimize structure of return device to ensure smooth return and stable furnace bed material.
4. Optimize the number of the blast cap and primary wind speed, to ensure the smooth fluidization of fuel and coking prevention.
ZG continues to be manufacturing, designing, engineering and servicing CFB boiler with Class A Boiler design and manufacture license since1945 for a huge number of satisfied customers. The price of CFB boiler is not uniform in terms of the price set according to the specificparameters of the boiler 's point of view,but ZG will supply the best price for customer.With independent right of import and export, ZG hasexported CFB boilers with good quality and suitable price to Argentina, Dutch, Italian, and Spanish, Tanzania, Nigeria, Serbia, Kazakhstan,Mongolia , Malaysia, India, Indonesia, Pakistan, Congo, Russia , Singapore,UAE, Thailand Bangladesh,etc

☞CFB Boiler Construction
Boiler using a single drum, natural circulation, generally divided into the front and the end of the two shafts.
The vertical shaft at the front is a total suspension structure, which is composed of membrane type water wall around.
From bottom to top, it is the primary air chamber, dense phase area and sparse phase area, and the tail flue is the high-temperature superheater, low-temperature superheater, economizer and air preheater from top to bottom.
The vertical shafts at the end are supported by a vertical cyclone separator. The lower part of the separator is connected with a return device and a ash cooler.
The combustion chamber and separator are equipped with anti-wear lining inside, the front vertical shaft with tube furnace wall, the outer metal plate, the rear vertical shaft with light furnace wall, by eight steel column to bear all the weight of the boiler.
The boiler adopts under-bed ignition (oil or gas), fractional combustion, primary air ratio of 50-60%, fly ash cycle for low rate, medium temperature separation of ash and slag discharge using dry, respectively from the water-cooled screw slag machine, ash cooler and dust collector dust bucket discharge.
The furnace chamber is the key to ensure the full combustion of fuel. The turbulent bed is adopted to make the fluidization speed be 3.5-4.5m /s. The appropriate furnace cross-section is designed.
