Experiment Device

Liquefied petroleum gas (LPG) is an important energy which is widely used in various fields of the national economy, and is one of the top 10 dangerous chemicals with inflammable, explosive dangerous. According to the need of LPG combustion and rescue, a set of LPG fire radiation experiment device was designed. The temperature and heat radiation flux of LPG flame can be gotten under different pressures and flow rates. The design is benefit for combustion and and emergency rescue research of large LPG tanks.

The Directly Irradiated Annular Pressurized Receiver (DIAPR) is a volumetric (directly-irradiated) windowed cavity receiver, designed for operation at a pressure of 10–30 bar, exit gas temperature of up to 1,300°C, and aperture radiation flux of up to 10 MW/m2. This paper presents test results obtained under various irradiation conditions and flow rates. Inlet aperture flux was up to 5 MW/m2; exit air temperatures of up to 1,200°C were obtained, while operating at pressures of 17–20 bar. Estimated receiver efficiency in these tests was in the range of 0.7–0.9. The absorber and window temperatures were 200-400°C below the permitted maximum, indicating that higher air exit temperatures are possible.

Artificial Grass

The paper presents a general overview of sport and floor lining products, such as artificial grass, which are used in residential premises and public utility buildings, as well as the hazards which ensue from the use of synthetic grass [1]. An outline was made of the requirements for the fire safety of civil engineering structures arising from their designation and usage type. The results were presented from studies conducted on four samples of synthetic grass with the main ingredients being polyethylene and polypropylene. An appraisal method was determined for flammable properties and flame spread on a horizontal sample subjected to a heat radiation flux gradient in a research chamber pursuant to PN EN ISO 9239- 1 [25] applicable for all types of floors. Based on the estimated value of critical heat radiation flux (KSP) below 3 kW/m2 and in addition to the flammability of products directly subjected to a flame according to PN EN ISO 11925-2 [27], a study was made of the suitability of selected samples of artificial grass by their categorisation to class Efl - i.e. easily flammable products. The classification of artificial grass selected for the needs of the studies, which has been verified in practice, and designated for use as decoration for gazebos, balconies, terraces and public utility facilities is only admissible in residential premises of type ZL IV.
