MAINTENANCE OF ASH HANDLING IN GAS PLANT BY REPLACEMENT OF THRUST BEARING
Abstract

Author(s): Pushpraj Yadav and Amit Kumar Kachwaha

In the process of Producer Gas Production; clinker/ash is formed as a waste material. This clinker is removed by equipment named as Ash Bowl which rotates on the “Guide Roller” by the application of hydraulic pressure. This process having many problems like formation of large size clinker which require excess hydraulic pressure, guide roller is unable to scatter the hydraulic pressure equally in all the direction on the ash bowl to crush the clinker, more hydraulic pressure is required for the movement of the ash bowl, more time is required to replace the guide roller for its maintenance. In order to eliminate above mention problems, guide roller has been replaced by the thrust ball bearing which improves productivity by reducing break down time, reducing total man power required & reducing maintenance cost.
