Fire whirl simulation measuring system

Abstract

The invention discloses a fire whirl simulation measuring system. The fire whirl simulation measuring system comprises a fire whirl generating device comprising a plurality of movable doors and slide rails, and a heat release rate determining device comprising a smoke collection cover, a smoke channel, a gas analyzer, a thermocouple, and an orifice plate flow meter. The measuring system is capable of simulating fire whirl phenomena having difference opening widths and different combustion forms, and is capable of determining change rules of heat release rate and combustion efficiency during a fire whirl generating developing process accurately by using various measuring elements.

Description

technical field [0001] The invention belongs to the technical field of fire safety, in particular to a fire whirlwind simulation measurement system. Background technique [0002] Fire whirlwind is a rotating strong convective fire phenomenon commonly seen in forest and urban fires. It has the characteristics of high burning rate, violent burning, and high flame temperature. At present, researchers at home and abroad conduct experimental research on fire tornadoes through two fire tornado simulation devices, slit type and rotating curtain type. The research content mainly focuses on the induction mechanism, combustion rate, flame height and temperature field distribution of fire tornadoes. Some achievements have been made both theoretically and experimentally. However, due to the lack of corresponding experimental equipment, the research on the heat release rate and combustion efficiency of the fire cyclone is almost blank, and there is a lack of research on different enviro...

AI Technical Summary

Problems solved by technology

However, due to the lack of corresponding experimental equipment, the research on the heat release rate and combustion efficiency of the fire cyclone is almost blank, and there is a lack of research on different environmental conditions (pressure, oxygen concentration, etc.) Quantitative analysis of the combustion efficiency of the fire cyclone, such as disk size, etc., so there is a lack of comprehensive and in-depth understanding of the combustion efficiency characteristics of the fire cyclone
