Oil shale combustion technology.

Doosan Guidelines on Superheater and circulation which were developed for large boilers are employed even in the smallest of the boilers. Travelling Grate Boilers is operated through burning of mustered husk and paddy straw and provides for superior combustion efficiency.

Atmospheric Fluidised Bed Combustion Boiler (AFBC)

Dumping Grate Boilers comprise generously sized grate and come with soot blower support for achieving on load cleaning of heating surfaces.

Providing for high operation reliability, these also ensure low down time as well as bolier less fouling and sagging possibilities.

Flexibility to choose from Charcoal start-up, Bouler assisted Charcoal start-up or pure Oil start-up. Membrane panels provide gas tight enclosure for better efficiency of boiler.

No clicker formation in our AFBC boilers. Bed evaporator tubes, pin stud SS welded to avoid tubes erosion. For abrasive fuels, special design considerations and provision of sacrificial shields.

These are specially demanded in saturated steam applications demanding uninterrupted operation on highly choking fuels.

Boilers – AFBC Boilers, Bi-Drum Boilers, Travelling Grate Boilers

Fuel-efficient furnace helps reduce acid rain. The industry areas includes pulp, paper, sugar plants, rice mills, chemical, food industries and others.

AFBC technology in both bubbling-and circulating-bed regimes is already considered commercial for units larger thanpounds per hour steam and there are at least 18 manufacturers of fluidized-bed combustors worldwide. Normally, superheaters are in convection and bed superheaters avoided for improved reliability.

There are more than 42 nos AFBC boilers operating worldwide which were designed as per Doosan Power System design and supplied either directly from the UK or produced by their licensees. Three stages a super heater of higher heating surface with two attemperator ensures consistent superheated steam temperature with more variations in demand. Paris, July 4, — Fives has signed an Optimised stud pattern for long life.

No expansion of tubes with drum.

A shared view of the future of their industry Tenders are invited for Collection, Loading, Transportation, dumping and leveling including loading and unloading of Boiler fly ash collected manually from all the areas from AFBC boilers and CFBC boilers ESP surroundings area as per the scope of work, required manpower should be arranged by the Tenderer.

The quality construction of these boilers also makes these deliver continuous operation support throughout the year. Looking for Product Name? Atmospheric Fluidized-Bed Combustion power generation, associated with coal-fired power plants. Modeling of decomposition and sulphation of oil shale carbonates on the basis of natural limestone.

Air nozzle and bed fuel nozzle made of SS for better life. Drum is being placed separately on boiler structural. The plant was revamped specifically for test purposes, with silo storage of coal for the AFBC unit limited to an eight-hour supply. High residence time in Furnace ensuring complete combustion.

Hot air for transport of fuel inside furnace through fuel feed lines.

Low fluidizing velocity for lower wear of bed tubes. Deep bed operation for better combustion. Thank you Your Enquiry has been sent successfully.

Coming with secondary air distribution system, these are pneumatically operated sectionalized dumping grate with two stage superheaters as well as single stage attemperator that allows in achieving accurate steam temperature control. Further, as these have small water content, these rapidly respond to changes in heat inputs and loads. Greater flexibility in erection sequence.

Atmospheric fluidized-bed combustion AFBC boilers provide offer efficient and reliable steam generation. The smallest of the boilers will have proper drum internals and cyclones for effective steam separation. Pioneering an active role to play in the empowerment of the community.

From 17 to 23 JuneFives will attend the Further six 6 nos AFBC boilers are under various stages of erection and commissioning. Fives to take the leadership in tube and pipe mills through the acquisition of OTO Mills, subsidiary of the Marcegaglia Group.

AFBC Boilers

Lesser FOT Furnace outlet temperature. But, even with a fuel-efficient AFBCthe sulphur gases go out the smokestack as pollution, so Becker introduced the limestone. The power plant will make use of the newest generation AFBC Atmospheric Fluidised Bed Combustion boilers and high pressure steam cycle to facilitate optimal plant efficiency. Drag chain feeders with VFD, for smooth flow of fuel to boiler as per demand.

ISGEC | AFBC Boiler | Atmospheric Fluidised Bed Combustion Boilers

Flexibility to choose from either Underfeed, Overbed feeding or even a combination of both. High pressure drop bed nozzles which ensures even air distribution even at low loads. Boilers works as steam generation units and finds use in industrial applications especially in areas where steam is required for process handling.
