Travelling Grate Boilers

Travelling Grate Boilers


ISGEC Heavy Engineering Ltd, an ISO 9001: 2008 certified company, offers Travelling Grate Boilers from its range of bagasse and biomass boilers. These are available in range – 20-250 TPH, pressure up to 125 bar, and temperature 545°C. These are suitable for cogeneration and captive power, and are multi-fuel firing (bagasse, coal, lignite, rice husk, cotton stalk, bagasse pith, olive trims, wood chips, cane trash and other biomass).
Highlights:

  • High efficiency features
    • Generous grate area, tall furnace and high residence time
    • Generously sized heat recovery system (eco and air heater)
    • Low excess air
    • High pressure air jets for good secondary air distribution
    • Grit refiring system
  • Lower auxiliary power consumption
    • Single pass boiler bank design
    • Low excess air
    • Low efficiency gas velocities
  • Environment friendly
    • Electrostatic precipitator type pollution control for limiting particulate emission up to 30 mg/Nm3

ISGEC has more than 582 water tube boiler installations across 28 countries. The company has wide experience in cogeneration, captive power applications. It uses technology from Foster Wheeler, USA, for PC fired sub-critical and super-critical boilers up to 1000MW for power plants. It also has the technology for fossil and biomass fired boilers – dump grate, travelling grate, atmospheric fluidised bed and circulating fluidised bed; and oil/gas fired boilers, at its world class manufacturing facilities.

  • Heavy-duty ribbed grate bars made of heat resistant spheroidal graphite (SG) ion
  • Self-lubricating graphite bearings for stoker shaft
  • Variable speed feeders for regulated fuel feed
  • Single or three drum feeder option for bagasse feeding
  • Two or three stage superheaters with single or two stage attemperator for accurate steam temperature control
  • Automated operations for single man operation
  • Minimum refractory used hence low maintenance
