Dependence of polyethylene combustion dynamics in a 1 m3 chamber on particle size

Autor: N. L. Poletaev

Publikováno v: Pozharovzryvobezopasnost/Fire and Explosion Safety. 31:6-12

Introduction. The results of a standard study on the explosion hazard of polyethylene air suspensions (PES) can contribute to the theory of turbulent combustion. For example, analysis of polydispersity data and values of the PES lean combustion limit

Particle size influence on the aluminum combustion dynamics in 1-m3 chamber

Autor: N. L. Poletaev

Publikováno v: Pozharovzryvobezopasnost/Fire and Explosion Safety. 31:6-13

Introduction. The results of a standard study of the explosibility of aluminum air suspensions (AAS) can contribute to the development of AAS combustion physics. In particular, a complex of information about the polydispersity and of the AAS low expl

Estimating the maximum size of explosive iron sulfide particles

Autor: N. L. Poletaev

Publikováno v: Pozharovzryvobezopasnost/Fire and Explosion Safety. 31:5-11

Introduction. There are estimates of the maximum size dcr of explosive particles of the two types of sulfide ores. The estimates are based on a qualitative approach to the dispersion analysis of combustible ore specimens (Soundararajan, Amyotte & Peg

Explosibility of nuclear graphite measured in a 1 m3 chamber

Autor: N. L. Poletaev

Publikováno v: Pozharovzryvobezopasnost/Fire and Explosion Safety. 31:15-21

Introduction. Nuclear graphite poses a threat due to the formation of the graphite dust – air mixture (GDAM) during the dismantling of decommissioned nuclear reactors. However, there is no clear answer to the question on the GDAM explosibility. A r

A research on rigid polyurethane foam resistibility to ignition from an electric arc welding spark

Autor: N. L. Poletaev

Publikováno v: Pozharovzryvobezopasnost/Fire and Explosion Safety. 31:14-20

Introduction. A fire investigation assumes that electric arc welding sparks (hereinafter referred to as “sparks”) are effective sources of ignition. However, the spark ignition of a combustible material depends on the contact time. This work has

A change in the air temperature inside a 20-liter chamber when air is added from the receiver

Autor: N. L. Poletaev

Publikováno v: Pozharovzryvobezopasnost/Fire and Explosion Safety. 30:23-29

Introduction. One of the reasons for the overestimation of the explosion hazard of dust inside a (20 ± 2)-liter chamber is the elevated initial temperature of the air suspension. The initial temperature is also raised by the process of filling the p

The heating of a stream of particles by thermal counter radiation

Autor: N. L. Poletaev

Publikováno v: Pozharovzryvobezopasnost/Fire and Explosion Safety. 30:15-22

Introduction. It is accepted that the depth of heating of the dust/gas/air mixture by the radiation of combustion products SR is equal to the length LR of the free path of radiation in the mixture. Numerical simulation of combustion of a gas-air mixt
