Matimba ACC Fan Gearbox Gears Manufacturing Technical Specification Report Unique Identifier: 2-1 Revision: 1 Page: 3 of 1 1 INTRODUCTION The figure below illustrates the basic working principle of the fan drive and heat transfer bundle for the Matimba ACC. Forced air flow is responsible for heat transfer between the air and the steam. From the illustration it is clear that if the gearbox is affected it will affect the heat transfer capabilities of the bundle and ultimately have negative effect on the ACCs performance. As can be seen on Figure 2 below, the power consumption during start up is over 7kW with the
