G_ Pulverized Coal Fired Boilers Single drum, single furnace, natural circulation pulverized coal fired boiler is regularly arranged with equilibrating ventilation, solid removal, all steel suspension structure, all welled membrane walls, control damper at the back passes. Platen super-heater, end super-heater and low temperature super-heater, economizer and air pre-heater are arranged along with smoke flow process in sequence. Technical Features 1. The unit is equipped with tilting corner nozzles for a tangential firing system to keep the air dynamic field inside the furnace without tilting 2. The furnace is optimally designed with proven structures proper arrangement and thermal parameters. A certain control margin are reserved sufficient to ensure complete combustion, high thermal efficiency , safe and stable operation 3. The thick-light patent is adopted for the primary air to allow easy firing and anti-sintering 4. The damper structure makes it a nice appearance 5. Three stages arrangement for super-heaters and two stages of water spray de-super-heating. 6. Tubular air pre-heater with the primary and secondary air separate arrangement.
