Automatic Mechanised screw fuel feeding makes fuel feeding OFF & ON when set temperature is achieved & reduced, respectively.Micro Processor Based VF 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.
