Among the many input parameters of a forging process (for a multi-stage process one can count more than 200 different inputs!) the following important inputs shall be mentioned: Forging Material characteristics (flow curve = f(temperature, strain, strain rate, micro-structure) Influence of heat coefficients Friction type and friction value as well as lubrication Heat transfer Ambient media and ...

Incineration is widely used to clean up Superfund sites. Modifications which improve the efficiency with which waste can be incinerated are therefore of interest to EPA. Oxygen/air burners are of interest because their installation on conventional incinerators can allow for significant increases in waste feedrate and on-line time. It is for this reason that an oxygen/air burner was evaluated in...

since the energy consumption has become one of the crisis of modern buildings, modeling the iranian past architecture patterns could be helpful. the shopping streets as one of the main sectors consuming energy locate near the open spaces it seems, therefore, they need more thermal comfort. however, using passive techniques, the iranian traditional bazaars architecture solved the problems regard...

Smog pollution is a severe social and environmental concern for the space-heating regions in China due to fossil-intensive space heating. To reduce polluting emissions improve performance, local government agencies should choose adequate cleaner technologies based on diverse conditions. This implies that all heating solutions be considered, including low-emissions fossil fuel district decentral...

In order to study the characteristics of thermal environment and comfort residential buildings during winter in hot summer cold (HSCW) climate zone China, this conducted a questionnaire survey field test. It was found that 70.9% HSCW had space heating equipment, among percentage air conditioning, electric equipment (electric oil-filled radiator fan heater) other were 56.0%, 27.6% 16.4%, respect...

In industrial applications, 90-150°C hot water needed during production processes is traditionally provided by fuelfired boilers. The use of fuel-fired boiler has a low efficiency of energy usage and potential danger of explosion. Byproduced 30-60°Cwaste water with large amount of energy is rejected to environment directly, which causes a great energy loss and thermal pollution. Seeking for a h...

Based on energy-relatedmeasurements,this articleevaluates the thermalperformance, energy-saving, indirect emissions and financial feasibilityof using heat pumps for hotel out-door swimming pools in subtropical climates. A rooftop pool of a city-centre hotel was investigated. It was found that the average coefficient of performance (COP) was around 2.0. The measured electricity consumption was 2...

This paper describes a kinetic study of the decomposition of waste printed circuit boards (WPCB) under conventional and microwave-induced pyrolysis conditions. We discuss the heating rates and the influence of the pyrolysis on the thermal decomposition kinetics of WPCB. We find that the thermal degradation of WPCB in a controlled conventional thermogravimetric analyzer (TGA) occurred in the tem...
