Increase in efficiency gas tube heaters for infrared heating

Infrared Thermopile Temperature Measurement Technique in Microwave Heating Systems

Temperature measurement in microwave systems is essential for thermally driven processes, namely, catalytic reactions and ceramic sintering. Although, the application of direct thermometry methods, namely, thermocouples, have been commonly articulated in the available literature, however, contacted temperature measurement mechanisms have aroused concerns associated with the disruption of the el...

Using an Infrared Gas Analyzer for Evaluation of Photosynthetic Activity in Some Iranian Pistachio Cultivars

Photosynthetic rates of six pistachio cultivars were studied including Ohadi, Kalleh-Ghochi, Akbari, AhmadAghaii, Rezaii Zoudras and Haratii. Measurements were done using OFF and ON shoots at different stages of fruit growth and development included: - Beginning of endocarp growth; - pith hardening; - Beginning of endosperm rapid growth; - end of embryo development; - ripening and harvesting ti...

Heating with Gas

Heating Cluster Gas

It is now generally agreed that some process prevents the diffuse gas in galaxy clusters from cooling significantly, although there is less agreement about the nature of this process. I suggest that cluster gas may be heated by a natural extension of the mechanism establishing the MBH − σ and MBH −Mbulge relations in galaxies, namely outflows resulting from super–Eddington accretion on to the g...

A Comparative Study of Heating Elements Used for the Development of Textile Heaters

The focus of this paper is to make a comparison between five different types of conductive, heatable samples. These textile samples have been produced according to the five most important implementation techniques such as knitting, weaving, embroidery, printing and nonwoven padding. The idea is to identify a conductive option best suitable for a heating application. This study was divided into ...
