FCKCP make travelling grate is cooled by pre-heated air required for combustion, and it is provided with metering holes resulting in greater combustion efficiency. Travelling grate continuously conveys the ash into the ash tray driven by variable speed hydraulic drive.
Travelling grate is pre-assembled at shop before dispatch to site. All the components included structural components, castings, doors, shaft with bearings & sprockets etc are assembled for proper fit with match marking and checked for alignment, expansion gaps which promotes smooth running of grate assembly at site.
Features of Fives Cail-KCP make Travelling Grate
- The grates are made of high quality heavy duty heat resisting iron casting for high temperature services.
- A sufficient number of non-lubricating graphite bearings are s located on drive and idler shafts. Bearings are high temperature split – sleeve graphite copper impregnated type. These bearings are interchangeable and reversible for additional life and do not require lubrication.
- Hydraulic drive will be hydraulic oil self-contained unit, directly coupled to the drive shaft. The unit is equipped with oil pressure relief valve to protect the stoker from damage in case an obstruction prevents grate travel. To compensate the variation of the ash content in the fuel, the drive output speed can be manually regulated to control the grate output travel from 0 to 11 RPH.
