THE BIOMASS FIRED POWER BOILERr
At start-up the water circulation starts very quickly because there are short overflow distances from downcomer to heating surface on water side. Due to these short distances all water filled tubes reach saturation temperature very quickly at start-up. Dangerous material stress caused by different thermal expansion does not occur.
A generous combustion volume above the Fluidised bed ensures complete combustion of the fuel, leading to low unburnt and high combustion efficiency. The combustion space is strategically expanded to reduce flame velocity and allow radiation to impart its energy to the water walls.
The water level in the drum keeps calm compared to Bi-Drum boiler since steam-water mixture pre-separates externally before entering the Drum.
Unlike Bi-Drum boilers where the downcomer tubes also act as riser tubes at high load, Bio-M has separate and distinct downcomers with large diameter. Steam bubbles forming at pressure fluctuations and high load change velocities cannot endanger the water circulation.
The admissible temperature variation gradient is significantly higher due to welded construction, leading to a quick start-up. Welded tubes have always been more reliable than expanded tubes.
BI-DRUM
THE BIOMASS FIRED BI-DRUM BOILER
Option of Bi-Drum Boiler configuration also available.
• Specially designed for Agro waste / Biomass Fuels.
• Three pass, High Efficiency Boiler.
• Packaged Boiler, no welding or expanding at installation site.
• Large Ash setting zone.
• Over bed feeding of Biomass / Agro-waste field like saw dust, rice husk, groundnut shell, almond shell.
• Special SS Nozzles ensuring long operating life
• Available in
– AFBC – Atmospheric Fluidised Bed Combustion.
– SFBC – Semi Fluidised Bed Combustion.
• Suitable for High potash fuels like Rice Straw & Mustard Straw.
• It consists of moving & fixed grate bars placed alternately in a staircase outline.
• The moving grates overlap the fixed grates and move it towards the ash zone.
• Fuel retention time on the grate is more which results in complete combustion.
• Speed of the grate & stroke length can be controlled and adjusted for complete combustion.
• Combustion air controlled in each zone.
• Suitable for a large variety of Biomass Agro-waste fuels.
• Specially designed for fuels of larger sizes such as cotton stalk, rice straw, soya straw, bagasse, palm bunch, agro-waste, briquettes.
