Oxidatively-heating property

After the drying time above referred to has passed, the temperature of the air bath is reset at a proper value, i.e., the nominal T, of the run, by means of the temperature dial on the air bath on the basis of the oxidatively-heating property of the substance tested to give estimated rates of increase in temperature of 1.25 BC/h in the adiabatic oxidatively-heating test. 

Chapter 8 Individual oxidatively-heating properties of the sawdusts of fifteen wood species and, procedure to calculate the Tc for a sawdust heap, having some one of several specific shapes including the class A geometries as well as an arbitrary size, placed in the atmosphere under isothermal conditions... 

The sawdust of every wood species is dealt with as a representative of gas-permeable oxidatively-heating substances herein. And, in the first half of the present chapter, are described the individual oxidatively-heating properties of the sawdusts of fifteen wood species, which are each measured, on the one hand, by TG-DTA performed in air and, on the other hand, by the adiabatic oxidatively-heating test performed in air. In this connection, the oxidatively-heating property of the sawdust of a wood species discussed herein is not necessarily consistent with the combustibility of the wood. The former subject, the oxidatively-heating property of the sawdust of a wood species, is concerned predominantly with some characteristics of the sawdust, which are revealed by TG-DTA performed for the sawdust in air or by the adiabatic oxidatively-heating test performed for the sawdust in air at the T, of 140 or 150 °C on the other hand, the latter subject, the combustibility of a wood, depends on the whole property regarding the combustion of the wood.

To begin with, the TG-DTA measurements were performed in air at atmospheric pressure with the aluminium open-cup cell, 5 mm in diameter, 2.5 mm in depth, at the value of of 2.5 K/min for the sawdusts of fifteen wood species, to see the individual oxidatively-heating properties as a whole, respectively. The TG-DTA curve of the sawdust of an average wood species is presented in Fig. 84.

It has been ascertained, in result, that, as to the above five kinds of metals or metallic oxides, the effects on the individual oxidatively-heating properties of the two kinds of sawdusts do not depend noticeably on wood species, respectively. 

In Chapter 8, the sawdust of every wood species is dealt with as a representative of gas-permeable oxidatively-heating substances. The individual oxidatively-heating properties of the sawdusts of fifteen wood species, which are measured, on the one hand, by TG-DTA performed in air, and, on the other hand, by the adiabatic oxidatively-heating test performed in air, respectively, are first described.
