摘要
A bench-scale apparatus for measuring the heat-release rate of pyrolysis vapors of a material sample includes an oven having a heated chamber for receiving the sample, a flue and at least one entry port, a radiometer having a radiation sensor disposed in relation to the flue of the oven such that an area into which burning pyrolysis vapors are directed from the flue is adjacent to the radiation sensor, a fuel-gas control valve in communication with the entry port of the oven, and an electronic flow meter for measuring the amount of fuel-gas passing through the control valve, wherein signals from the radiometer operate the fuel-gas control valve to provide an amount of fuel-gas sufficient to maintain a flame of the vapors at a predetermined height, and wherein the meter measures the amount of fuel-gas such that the measurement of the meter is used to indicate the heat-release rate of the pyrolysis vapors. An apparatus for measuring the sootiness of pyrolysis vapors of a material sample, including an oven, a smoke detector, a diluent control valve and an electronic flow meter is also disclosed, as well as processes for measuring large-scale flammability hazards of materials, sootiness of flames of materials, and heat-release rate of flames of materials.
