Design for Maintainability: The Innovation Process in Long Term Engineering Projects

Whether it's turning off lights, idling back process equipment and fixing compressed air leaks to energy audits and installing compressed-air management systems-reducing utility costs can take several forms. As with any project, the return on investment should guide you on the projects that you select.

It's hard to imagine belt conveyors anywhere playing a more important role than at South Africa's Kendal Power Station. Here, the world's largest black-coal-fired electrical generating complex converts up to 1.4 million tons a month into more than 4100 megawatts, enough to supply three cities the size of nearby greater Johannesburg.

This article has several related themes. The main purpose is to give an overview of the engineering education process, relating theory to practical application. As part of this overview, I express gratitude to the scientists, mathematicians, and engineers who have guided my own education. This education is the foundation of my engineering career, as my experiences demonstrate.

For the foreseeable future, the “job of the future” will exist in a world that wrestles with issues of outsourcing, offshore design and manufacturing, and generally uncertain employment prospects. Among the job seekers, aspiring engineers need to develop effective ways of finding and keeping employment in this murky environment.

The moral: Even when you think you have found the best solution, put the problem aside and then ponder it again. A fresh look may lead to an even better solution. As for the integral desuperheater, it is too elegant a solution to go to waste. Perhaps you may have a use for it.

The cost per kWhr, the "cost of producing electricity", is the cost of the energy which is taken out of the steam by the turbine generator system and converted into electricity. The following paper discusses calculation methods for determining this cost -- a critical step in the process of evaluating cogeneration feasibility.
