heating rate

heating rate

The rate at which temperature is raised, as for example in an autoclave or kiln; usually expressed in degrees per hour.

where [E.sub.a] describes the activation energy, [beta] is the heating rate, R is the gas constant and T is the temperature.
The influence of reorganization on the heating curve can be analyzed by varying the heating rate. The device can simulate technical processes in which rapid cooling occurs.

Opposite to mass measurements on stabilized PAN nanofibers, showing an approximately constant value of ~85% of the original mass, here, a clear heating rate dependence is visible for the lower heating rates.
A brief discussion of commercial water heating techniques will help readers better understand the needed heating rate discussions in the sections below, and the differences between "bottom-up" versus "top-down" heating.
Investigators [8] found that activation energy value increased with increasing heating rate up to 15 [degrees]C/min, whereas no such trend was observed with higher heating rates.
A 10-50 mg of finely chopped fibres samples were placed in a small aluminium pan which was suspended in TA Instruments Q500 v6.1, where the gomuti fibres are heated up to a higher temperature of 600[degrees]C in the [N.sub.2] atmosphere at the heating rate of 5[degrees]C/min.
The experimental results showed that: (1) The effect of tar cracking as the pyrolysis temperature, the heating rate, the volatilization of pyrolysis char and particle size increasing is better and better.

Decomposition was carried out on NETZSCH STA 409 PC simultaneous analyzer with the heating rate of 10, 20, and 40[degrees]C/min from room temperature to 1000[degrees]C in either [N.sub.2] or C[O.sub.2] atmosphere.
Until now, studies on the mechanical properties of rocks have somewhat overlooked the influence of heating rate. Actually, the fundamental reason for different heating rates is not the temperature, but the heat injection rate and/or combustion speed during underground coal gasification and coal-bed methane mining.
