Biomass was subjected to conventional and microwave pyrolysis, to determine the influence of each process on the yield and composition of the derived gas, oil and char products. The influence of pyrolysis temperature and heating rate for the conventional pyrolysis and the microwave power was investigated. Two major stages of gas release were observed during biomass pyrolysis, the first being CO...

The purpose of this study was to determine if the arterial baroreceptor reflexes modulate the sympathocirculatory responses to acute heat stress. To address this, arterial pressure, heart rate, mesenteric and renal blood flow velocity (Doppler flow probes), arterial plasma norepinephrine, and colonic temperature were measured before and during whole body heating (42 degrees C ambient temperatur...

Evaluation of self-heating propensity of vegetable oils can be useful for determination of critical parameters of the system (porous material – vegetable oil), which must be fulfilled to achieve spontaneous ignition. However, the results strongly depend on the preparation of the sample and the type of method used for the evaluation of self-heating propensity of the oil. The safety calorimeter S...

Coconut is a high-quality agricultural product of the Asia-Pacific region. In this paper, coconut shell which mainly composed of cellulose, hemicellulose, lignin was used as a raw material for coconut shell oil from coconut shell pyrolysis. The influence of the pyrolysis temperature, heating rate and particle size on coconut oil yield was investigated, and the effect of heating rate on coconut ...

Climate change affects the demand for energy consumption, especially for heating and cooling buildings. Using daily mean temperature (Tmean) data, this study analyzed the spatiotemporal changes of the starting date for heating (HS), ending date for heating (HE), length (HL) and heating degree day (HDD) of the heating season in central heating zone of China. Over China's central heating zone, re...

Convection of an internally heated fluid, confined between top and bottom plates of equal temperature, is studied by direct numerical simulation in two and three dimensions. The unstably stratified upper region drives convection that penetrates into the stably stratified lower region. The fraction of produced heat escaping across the bottom plate, which is one half without convection, initially...

We measure ion heating following transport throughout a Y-junction surface-electrode ion trap. By carefully selecting the trap voltage update rate during adiabatic transport along a trap arm, we observe minimal heating relative to the anomalous heating background. Transport through the junction results in an induced heating between 37 and 150 quanta in the axial direction per traverse. To relia...

Lightning strike simulations have used decomposition models, derived from TGA experiments, to model material behaviour at elevated heating rates and temperatures. Such conducted non-isothermally low rates, are extrapolated conditions assumed during a lightning event. However, no experiments been carried out in literature verify understand the impact of these extrapolation assumptions. This work...

In this paper solar assisted heating and absorption cooling system and domestic hot water needs for a hotel having fifty rooms in Antalya have been investigated. First of all, solar radiation and meteorological data for Antalya and heating and cooling loads of the hotel building are given. For the heating cycle, active systems using liquid as the working fluid; and for the cooling cycle, solar-...
