Measuring rate of heat release by oxygen consumption

Fire Technology, 1991
This paper provides a comprehensive set of equations and guidelines to determine the rate of heat release in full-scale fire tests based on the O2 consumption principle. The approach is different from other investigators as the enphasis is on full-scale fire test applications and the use of volumetric flow rates is avoided.

Prediction Of The Heat Release Rate Of Wood

Fire Safety Science, 1986
A method for predicting the heat release rate of wood for different thicknesses, moisture contents, and exposure conditions is described. A model has been set up and calculations have been made on a microcomputer. Heat release rates and effective heats of combustion were measured as a function of time and external radiant flux on 12.5 mm thick dry ...

Upholstered Furniture Heat Release Rates: Measurements and Estimation

Journal of Fire Sciences, 1983
A new instrument, termed a furniture calorimeter, has been constructed and placed into operation for measuring furniture heat release rates based on oxygen consumption. Using the furniture calorimeter, burning rate information has been obtained on a series of 13 chairs, loveseats, and sofas, most of them specially built to permit direct comparisons of

Heat Release Rates of Lumber and Wood Products

1983
Heat release rates (HRRs) were determined for twelve wood products on each of three similar HRR calorimeters. Linear regression treatment of these data showed reasonable correlation among the three instruments. The data showed that HRR decreases with increasing moisture content and increases with increased external radiant flux.

Measuring rate of heat, smoke and toxic gas release

Fire Technology, 1972
Is the present concept of fuel loading a good measure of fire hazard? The author thinks not. Combustibility, smoke release, and toxic gas release should be examined over a wide range of exposure conditions before the fire hazard of materials can be properly evaluated.

Rate of heat release measurement using the Cone Calorimeter

Journal of Thermal Analysis, 1989
The rate of heat release is the most important parameter for characterising an unwanted fire. The oxygen consumption principle has accelerated the development and use of equipment of measure rate of heat release. The Cone Calorimeter is the most significant of small scale instruments in this field.

Heat Release Rate from the Combustion of Uranium

Fuel treatment is planned at the Argonne National Laboratory on EBR-II spent fuel. The electrochemical treatment process is carried out in a cell with an argon atmosphere to prevent any reaction. The amount of fuel processed at any time is limited by the amount of energy which could be released by metal combustion if air is inadvertently allowed into ...

Predicting heat release rate from fire video data:

A novel approach for estimating transient heat release rate from fire images and video using deep learning techniques is presented. The heat release rate (HRR) is the most critical parameter in characterizing the fire hazard and thermal effects of a burning item.

Controlling Object Heat Release Rate using Geometrical Features

2017
An experimental study was conducted to determine the effect of complex geometries on the burning rate of materials made using additive manufacturing. Burning rate of objects is dependent on material composition, as well as on the shape of the object itself.
