Features:
  • Single Drum Corner pipes design, which is the only choice for a very high pressure and temperature Boiler, is being offered even for medium pressure Boiler which is highly acclaimed all over ward for its reliability of performance & sturdiness.
  • The Drum does not form an integral part of the water - Steam circulation circuit, as all the water and Steam do not need to flow through the drum.
  • By the arrangement of Top Headers, the re-circulated water does not flow to the drum, but re-circulation is thro' Top & Bottom Headers. This ensures better steam quality from the drum, as steam separation starts from Headers.
  • Bi-Drum Design, the Bank Tubes are expanded into two Drums. The expanded joints in high-pressure Boiler are a constant source of trouble. Where as in the Single Drum Designs, the Bank Tubes are in Panels and welded. There are easily approachable. Hence Tube replacement and maintenance in future is very easy.
  • Single Drum Design, the Drum is Outside the Flue gas path and there are no Tube Holes expect for opening for 4 Headers. These openings are also fully compensated which results in much thinner shell plate thickness and minimum thermal stress.
  • Water Wall 2.1/2" size Tubes/Pipes are spaced 1" apart. This provides the larger volume of Water in our Furnace Walls and contributes to a faster load response. In addition, our uniquely designed Drum Internals can handle varying loads without circulation disruptions on carrying over.
  • Furnace Wall Water Cooling includes side walls & Bed Coil, eliminating Refractory and its attendant Maintenance.
  • Gas tight setting Membrane provides the gas tight setting, which eliminates dew - point sulfur corrosion and outages caused by gas leaks. Par's Membrane Panels use larger Dia Tubes and Small Membrane spacing which provides the best combination of heat transfer efficiency & Maintenance accessibility.
  • Drum Internals provides high Steam purity.
  • Direct in Bed Feeding System: Firing is neither Under Bed nor Over Bed but directly in the Bed. This arrangement makes it possible to use the wide range of Solid Fuel.
  • Pressurized Economiser & Air Pre Heater is provided for better waste Heat Recovery and to increase the overall Thermal efficiency of the Boiler.
  • IBR Economiser, as well as Air Pre Heater both, are incorporated to minimize dry Flue Gas losses and maximize the Waste Heat Recovery.

Approx. Price: Rs 12 Lakh / Unit

Product Details:

Steam Generation Capacity0.5 TPH up to 25 TPH
Working PressureUp to 30 Kg/Sq.Cm.
FuelCoal Dust, Lignite Dust, Saw Dust, Bio-Mass, Wood Chips, Agro-Waste, Rice Husk, GN Shell, DOC , Mustered Stalk, Cotton Stalk, Coffee Waste, Spice Waste Dust, Empty Palm Fruit Bunches (EPFB), Spent Bleach Earth (SBE), Baggase

Features:
  • 4 Pass design ensures better heat utilization & ultimate thermal efficiency
  • Fluidized Bed Combustion furnace ensures very high combustion efficiency, up to 95% even with fuel, having very high ash & fine contents and having very low calorific value
  • The straight tube in generating bank enables manual cleaning & easy inspection.
  • The rectangular headers are of welded type box headers with individual opening against each tube at both ends of generating bank. Hence, for cleaning & maintenance of any single tube only single door cap, weighing just 1.5 kg has to be opened.
  • Larger tube diameter in generating bank, i.e. 76.2 mm OD, enables easy manual cleaning.
  • Intermediate tube supports in the generating bank, which prevents tube sagging contributes to higher boiler life.
  • The wide gap in tube spacing ie. 160 mm pitch, prevents inner tube space plugging by soot deposition, which permits trouble free operation without external cleaning as clogging of tube space with soot does not take place.
  • The free floating front header takes care of longitudinal thermal expansion. Hence, thermal stresses are not developed during heating. This design enhances boiler life too.
  • Man hole opening at both sides of the drum for easier access to drum internals.
  • Larger diameter drum coupled with drum internal steam separators ensures dry steam even at full main steam valve opening.
  • Moderately larger furnace area and higher free board height, above grade, make the boiler capable of burning low grade, high volatile & ash contained solid fuel efficiently without reducing rated steam generating capacity.
  • No inventory of spares, since nothing special is employed which is necessary to be procured urgently from us or which is not available in the free market.

Get Best Quote
Approx. Price: Rs 3 Lakh / Unit

Product Details:

Steam Generation Capacity 1 TPH to 15 TPH
Working PressureUp to 17.5 Kg/Sq. Cm.
FuelCoal Fired

Advantages:
  • High Efficiency - FBC boilers can burn fuel with a combustion efficiency of over 95% irrespective of ash content. FBC boilers can operate with the overall Thermal efficiency of 82% (plus or minus 2%).
  • Compact in Boiler Size - High heat transfer rate over a small heat transfer area immersed in the bed result in overall size reduction of the boiler.
  • Fuel Flexibility - FBC boilers can be operated efficiently with a variety of fuels. Even fuels like Coal, Husk, Agro waste can be burnt efficiently. These can be fed either independently or in combination with coal into the same furnace.
  • Ability to Burn Low-Grade Fuel - FBC boilers would give the rated output even with inferior quality fuel. The boilers can fire coals with the ash content as high as 60% and have calorific value as low as 2,500 kcal/kg. The Even carbon content of only 1% by weight can sustain the fluidized bed combustion.
  • Ability to Burn Fines - Coal containing fines below 6 mm can be burnt efficiently in FBC boiler, which is a very difficult to achieve in conventional firing system.
  • Low Corrosion and Erosion - The corrosion and erosion effects are less due to lower combustion temperature, the softness of ash and low particle velocity (of the order of 1 m/sec).
  • Easier Ash Removal - No Clinker Formation- Since the temperature of the furnace is in the range of 750 - 900° C in FBC boilers, even coal of low ash fusion temperature can be burnt without clinker formation. Ash removal is easier as the ash flows like liquid from the combustion chamber. Hence less manpower is required for ash handling.
  • Less Excess Air - Higher CO2 in Flue Gas - The CO2 in the flue gases will be of the order of 14 - 15% at full load. Hence, the FBC boiler can operate at the low excess air - only 20 - 25%.
  • Simple Operation, Quick Start-Up - High turbulence of the bed facilitates quick start up and shut down. Full automation of start up and operation using reliable equipment
  • Fast Response to Load Fluctuations - Inherent high thermal storage characteristics can easily absorb fluctuation in fuel feed rates. Response to changing load is comparable to that of oil fired boilers.
  • No Slagging in the Furnace-No Soot Blowing - In FBC boilers, volatilisation of alkali components in ash does not take place and the ash is nonsticky. This means that there is no slagging or soot blowing.
  • Provisions of Automatic Coal and Ash Handling System - Automatic systems for coal and ash handling can be incorporated, making the plant easy to operate compared to oil or gas fired installation.
  • High Reliability - The absence of moving parts in the combustion zone results in a high degree of reliability and low maintenance costs.
  • Reduced Maintenance - Routine overhauls are infrequent and high efficiency is maintained for long periods.
  • Quick Responses to Changing Demand - A fluidized bed combustor can respond to changing heat demands more easily than stoker fired systems. This makes it very suitable for applications such as thermal fluid heaters, which require rapid responses.
  • High Efficiency of Power Generation - By operating the fluidized bed Boiler at elevated pressure, it can be used to generate power with a back pressure steam turbine. And the steam from the turbine exhaust can be utilized for the process while generating the power.
