At Stora Enso Fine Paper Nymölla Mill there is a wish to reduce its dependency on external produced electric power. One suggestion that has been made is to install a hot air gas turbine. The purpose of this thesis is to see if it is thermodynamic and economical to go through with the project with the hot air gas turbine. It is of great importance that the boiler-process remains as unchanged as ...

In the context of a world energy crisis, only solution to control situation is in management energy. One most important keys optimization electrical components. This article presents complete numerical and experimental study aiming for water heaters household use. The conceives minimization consumption simultaneously with time heat water. Firstly, thermal model well adapted case constructed val...

In this paper, a cascade control strategy is applied to the temperature inside hybrid solar-gas dryer. order use dryer even at night and in unfavorable weather conditions, drying chamber heated by two systems. The first one solar air heater second gas heater. collector relatively slow compared heating system. Static dynamic studies were established have revealed nonlinear behavior of each subsy...

With the heater pipeline leakage experiment conducted on the experiment table, inner pipeline leakage of heater was studied through the leakage failure detection system. The frequency distribution and the amplitude of acoustic emission signals of leakage versus internal pressure were analyzed. Variations of signals versus leakage aperture and dissemination distance were summarized. According to...

Renewable hydrogen may be produced in the near term at a cost that is competitive with natural gas reforming by integrating hydrogen production with existing industrial utilization of agricultural residues. A team of government, industrial, and academic organizations is developing a steam reforming process to be demonstrated on the gaseous byproducts from a process for making activated carbon f...

Rising greenhouse gas emissions raise the risk of severe climate change. The household sector’s greenhouse gas emissions have increased over time as more people drive gasoline cars and consume electricity generated using coal and natural gas. The household sector’s emissions would decline if more households drove electric vehicles and owned solar panels. In recent years automobile manufacturers...
