Hvater Tube Development

Some insight into the very careful and detailed development carried on by MAN/MWM was given by Zacharias (1973) in a scholarly discussion of the interrelation of computation and design in the development process. Part of this presentation included a discussion of stress and temperature distribution in heater tubes. Fig. 14.11 shows the elastic stress distribution in a heater-tube wall due to thermal strain and internal pressure. Fig. 14.12 shows the computed temperature distribution in a heater tube and Fig. 14.13 shows the computed creep-limited life expectation for heater tubes of different nickel-base steels.

Solar Panel Basics

Global warming is a huge problem which will significantly affect every country in the world. Many people all over the world are trying to do whatever they can to help combat the effects of global warming. One of the ways that people can fight global warming is to reduce their dependence on non-renewable energy sources like oil and petroleum based products.
