SPOUTED BED TECHNIQUE TYPE FURNACE FOR COMBUSTION OF HIGH ASH NON-CAKING FINE AND SLACK COAL

摘要

Spouted bed technique type furnace for combustion of high ash non-caking fine and slack coal comprising conical shaped Coal Feeding Chute situated at the top of the furnace followed by Feed Controller, which in turn is connected to the Reactor being a long cylindrical tube with Cone situated at the bottom of the said Reactor providing an Outer for ash, an Inlet Nozzle with a fine orifice situated at the bottom of the said Cone, an Ignition Coil situated at the bottom of the furnace for radiating large amount of heat; LPG Inlet and Air Inlet in the form of two coaxial cylindrical tubes situated at the bottom part of the furnace facing the said Ignition Coil and Manometer Pressure Tappings being provided laterally at the upper part of the said Reactor and at the bottom of the said Cone for measuring the pressure in the Reactor and Thermocouple being provided adjacent to the said Feed Controller inside the said Reactor for measurement of temperature inside the Reactor, the products of combustion and unburnt coal and ash being let out through the outlet tube provided at the top of the said Reactor and next to the Thermocouple, the Cyclone Separator connected to the said Outlet Tube being utilized to separate the unburnt coal and ash from the bottom of the cyclone separator and the flue gases from the top of the cyclone separator which are then analysed through a Sampling Proble.
