Unloading System for FA Silo:<\/strong> The FA Silo shall have Four outlet points. First and second outlet point shall be provided with fly ash unloading spouts for unloading of fly ash into closed tankers and third outlet is provided with an ash conditioner for moist ash disposal into open trucks. The fourth outlet is provided with blind flange for future opening.<\/p>\n\n\n\nConveying air requirement for both the units is met from a common bank of CA compressors dedicated for fly ash handling.<\/p>\n\n\n\n
Separate Instrument Air compressors have also been provided for complete ash & limestone\/bed material handling systems.<\/p>\n\n\n\n
PRINCIPLE OF OPERATION (Dense Phase Pneumatic Conveying system):<\/h2>\n\n\n\n
The operation of the system is simple and completely automatic. System has dual operatability either through level probe material sensing or timerbased mode.<\/p>\n\n\n\n
In timer based mode, the system shall convey material automatically in batches at preset programmable interval of time.<\/p>\n\n\n\n
In level probe mode, level sensing probe provided in the hopper above conveying vessels or transfer vessel shall sense the presence of material in the hopper and initiate the conveying cycle.\u00a0 Dome valve shall open and allow the material to gravitate into the transfer vessel for a preset time & then close automatically. On closure of dome valve, its seal gets inflated and signals the conveying air injection into the transfer vessel. The vessel gets pressurized and material resistance help pressure build up and conveys the material through steel piping to the destination silo.<\/p>\n\n\n\n
When conveying is complete, the pressure drops down and is sensed by the control system, the air supply to the system is stopped and the cycle is complete now. The system is ready for the next cycle.<\/p>\n\n\n\n
The total system is made automatic by use of level probe in destination silo to control the transfer of material. Complete system is flexible enough and programmable and automatically operated through a PLC based central control panel.<\/p>\n\n\n\n
BED MATERIALHANDLING SYSTEM (Dense Phase Pneumatic Conveying system):<\/h2>\n\n\n\n
Total of 2 sets (One for each boiler) of bed material conveying system is provided for two boilers.<\/p>\n\n\n\n
Bed Material is fed into MS surge hopper (by Purchaser). The Surge Hopper is provided with two sets of conveying systems, each connected to an individual conveying pipeline for conveying bed material to the boiler bunker.<\/p>\n\n\n\n
At top of each boiler bunker, Vent Filter (reverse pulse jet type) andcontinuous level monitoring is provided.<\/p>\n\n\n\n
LIMESTONE CONVEYING SYSTEM:<\/h2>\n\n\n\n
Continuous conveying system is provided for limestone handling. Macawber Beekay\u2019s this technology has the capability to convey a wider range of materials with variable particle sizes using lower positive air pressures. This form of conveying is ideal for long distanceconveying and handling materials which are difficult to handle.<\/p>\n\n\n\n
Total of 2 sets (One for each boiler) of limestone conveying system is provided for two boilers.<\/p>\n\n\n\n
Crushed limestone from crusher house is collected in Product Hoppers below which conveying vessels are provided for conveying limestone to boiler bunkers.<\/p>\n\n\n\n
System at Limestone Bunkers:<\/p>\n\n\n\n
At top of each boiler bunker, Vent Filter (reverse pulse jet type) and continuous level monitoring is provided.<\/p>\n\n\n\n
Dedicated conveying air compressors have been provided to for limestone conveying system, the other auxiliaries \u2013 common to ash handling system are retained.<\/p>\n<\/div>\n<\/div>\n<\/div><\/div>\n","protected":false},"excerpt":{"rendered":"
