Wind field environment pool fire burning rate test device for eliminating wind interference

Abstract

The invention provides a wind field environment pool fire burning rate test device for eliminating wind interference. The device mainly comprises a liquid supply tank, a liquid stabilization pool, a combustion pool, an electronic balance, a wind shielding plate, several thermocouples, an anemometer and a parallel air blower. The liquid stabilization pool is welded to a center of the liquid supply tank, a bottom is connected to the combustion pool through a fuel connection pipe, and the liquid supply tank is placed on the electronic balance through a liquid supply tank support and a bottom plate. The parallel air blower can flexibly and quickly create a required predetermined wind field environment according to parameter adjustment of the number of air blowers, wind power, an angle and the like, and the wind field environment is ensured not to affect measurement of fuel quality so as to accurately study combustion characteristics of liquid fuels under various wind fields, and a basis is provided for relevant tests and standard establishment.

Description

technical field [0001] The invention relates to liquid fuel combustion characteristics and fire evolution laws in a wind field environment, and more specifically relates to a test device for testing the combustion rate of a pool fire in a wind field environment that eliminates wind interference. Background technique [0002] The wind field environment is one of the important factors affecting the combustion of fire combustibles. In many fire scenarios, the effect of the wind field environment on the combustion process exists, such as car fire accidents in tunnels, room fires in high-rise buildings, and fires in field oil fields. Accidental fires and mountain forest fires, etc., wind farms play an important role. Under the influence of wind speed and wind direction in the wind field, the burning rate of fuel and the physical appearance of the flame will be significantly different from those without wind. Previous literature has done some research on liquid fuel fires in wind...

Problems solved by technology

However, this type of method also has obvious limitations: first, the wind field directly acts on the fuel pan used for combustion, and the fuel pan is placed on the electronic balance for mass measurement, so it is inevitable that the wind force will affect the The electronic balance produces interference, the quality data obtained and the fuel burning rate are not accurate, and the error has a large random disturbance; secondly, the creation of the wind field environment is relatively simple, usually a parallel wind field, while for real The common swirling wind field and turbulent wind field in fire cannot be reproduced flexibly. Therefore, in general, the existing test methods cannot meet the in-depth analysis of the combustion behavior of pool fires in the wind field environment.
