Heat integrating low temperature chimneys have been developed, with different air flows for different functions. The chimneys were designed and manufactured at a thermal engineering factory in Lulea, Sweden in 1997, and functioned very well. They were developed for low temperature chimneys, which are used in the burning of solid fuels in power plants and boilers, such as peat and wood pellets. The chimneys are injected with air at two different pressures.
Increased demands and greater amounts of wash water have made "The Open University" concerned with calculation of drinking water needs and water utilization. The study involves faculty from the Department of Biology. Preliminary calculations have shown that WHO guidelines for water needs in meat-producing countries, such as the UK and USA, is probably not suitable for many developing countries. Example calculations for Nepal suggest that the guidelines must be uprated by factors of up to three for cattle (due to the amount of drink-water available), and by factors of two to three for sheep and goats. The students are using the spreadsheets and lab data at the farm to test the validity of their calculations.
In order to better utilise the available data, estimates of future emissions are needed. To meet this need, Energy Technology develops a decision support model that allows users of energy technology research and policy, to quantify potential energy service-life energy gains and emissions savings. The model was developed as an added value to the International Energy Agency (IEA) Technology Evaluation Centre (TEC) Decision Support System (DSS), now being developed by Soine. The system is aiming to transform the TEC DSS to provide decision support specifically for energy technology, but with a strong focus on energy technology research policy development.
The dependence between the physical parameters of wood, the most commonly used raw material in the construction industry, and the strain-governed mechanical properties of wood was determined. The dependence is linear, with zero intercept. The calculated mechanical constants of elasticity and strength correspond well to experimental values. The calculated elastic modulus corresponds well to preliminary experimental values. The calculated strength corresponds well to preliminary experimental values. d2c66b5586
