4 Pass design, ensures better heat utilisation & ultimate thermal efficiency. Fluidised 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. 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. Wide gap in tube spacing i e. 160 mm pitch, prevents inter 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. 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 grate, makes the boiler capable to burn low grade, high volatill3 & 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.

The boiler is required to be offered for open & hydraulic test inspection once in 2 years, to Boiler Inspector.. Boiler is a combination of Smoke Tube & Water Tube technology. Membranes Water wall external furnace makes use of direct radian o heat from furnace. Being an external membranes wall furnace, boiler is very much suitably for fuel like Lignite / Agro waste / Wood etc. With an option of FBC furnace, cheaper fuel like Saw Dust can be used, which is other impossible to be used in hand fired boiler. High thermal efficiency of 75 % ±2 % can be obtained, with hand firing With an option of FBC system with a Micro Processor Based fuel feed - & combustion air pre heater, efficiency unto 87 % +1-2 % can obtained. Though approved by IBR, one can enjoy all freedom of a Non IBR Boil-and still meets the mandatory requirements, pertaining to safety. Pay back period of the new boiler plant, against an Oil fired boiler, is less than 6 Months.,

Salient Features: 4 Pass Design ensures better heat utilisation & Ash separation. With Fluidised Bed Combustion furnace design, very high Thermal Efficiency of 80%+-2% can be achieved. Automatic Mechanised screw fuel feeding makes fuel feeding OFF & ON when set temperature is achieved & reduced, respectively. Micro Processor Based V/F fuel feed drive is used to adjust the rate of fuel feeding as per Plant load requirement. Most of the Solid Fuels, including Crushed Coal / Lignite / Agro waste / DOC / Saw Dust can be used in this system. Large size Air Pre-Heater / Water ,Pre-Heater, reduces dry flue gas losses and improves the Waste Heat Recovery and increases combustion Air Temperature. Radiant Coils installed directly on FBC Furnace makes maximum utilisation of Furnace radiation heat. Mechanical Dust Collector arrests the fly Ash from Flue gas, before exhausting to Chimney. Ash collection pit is provided below convective coils.

Working Pressure : Up to 150 Kg/Sq.Cm.

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. Coal containing fines below 6 mm can be burnt efficiently in FBC boiler, which is a very difficult to achieve in conventional firing system. 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.

Like Two Field ESPs, Three Field ESPs, On-Line Pulse Jet Bag Filter Plants, Wet Scrubbers, Cyclones, Mechanical Dust Collectors. Electrostatic Precipitator (ESP) Electrostatic precipitator (ESP) is a widely used device in so many different domains to remove the pollutant particulates, especially in industrial plants. And as it name implies it uses the electrostatic fundamentals (corona discharge) for trapping and removing industrial emission like boiler exhaust. That’s why it is named as ESP. Physical components of Electrostatic Precipitator Collecting and discharge electrodes Collecting electrodes plate type and tube type. Occasionally made of stainless or an alloy steel. Generally 0.05 to 0.2 cm in thick. Discharge electrodes plate type and wire type made of high carbon steel but also can be constructed of S.S. copper, titanium alloy & aluminum Spikes having a corona material. Comparison of Bag-Filter and ESP Comparison based on parameters For low emission less than 30mg/nm3 go for a bag-filter For high temperature more than 260˚c go for ESP If moisture content in flue gas is more than 20% go for bag-filter If dust resistivity is very high or very low which will be difficult to charge in ESP go for a bag-filter. In power industry normally we find ESP but in cement industry bag-filter is generally used due to dedusting action.
