The South African Institute of Materials Handling

Sample

The South African Institute of Materials Handling (SAIMH) is a Non-Profit organisation set up with an objective to encourage the transfer of knowledge associated within the fields of Bulk Materials Handling (conveyors, stacker, reclaimers, tipplers, train loading systems, etc.) through a combination of seminars and networking sessions. The SAIMH is made up of professional engineers, each practising their trade in a variety of organisations who volunteer their time to execute the SAIMH’s objective. The main aim is thus to promote the advancement of the art, science, theory and practice of the Bulk Materials Handling principles and techniques.

Boiler feed pumps in power stations consume typically 3 - 5% of their unit's power output. Consequently, any improvement in their efficiency and energy balance will directly enhance the economic efficiency of the entire plant. • • •
