DR 666-40R Combustion Laboratory Testing System

【Scope of Application】: 
The combustion dummy experimental device simulates the human body (dummy) wearing clothing, exposing it to the heat of a burning flame to test the changes in the dummy's surface temperature, predict possible second and third-degree burns to the skin and the total percentage of burn area, and accurately forecast the degree of skin burns on the body. In the high-simulation experimental room that mimics the high-risk environment of a fire scene, using the combustion dummy testing system, various fire protection equipment such as fireproof clothing and military uniforms can be evaluated for their flame retardant performance and the factors influencing them.
It truly simulates and conducts comprehensive tests on the protective performance of professional clothing.

I. Combustion Laboratory System
1. The combustion laboratory adopts an overall fireproof structure. The overall structure is composed of a metal frame and flame-retardant materials.
2. Dimensions of the combustion chamber: 4160mm (length) × 4160mm (width) × 4500mm (height). (The construction space height should be at least 4000mm, and the building area should be at least 5000mm²)
3. Ventilation and Exhaust System
This test chamber is equipped with a pre-designed fan. It can automatically adjust the air volume according to different stages of the experiment for ventilation and exhaust. That is, it can ensure the ventilation and oxygen supply inside the chamber during the experiment, and quickly discharge the exhaust gas from the chamber after each combustion, and replenish the cooling air after data acquisition. 

II. Explosion Prevention and Safety Control System
1. Burner: 6 sets of 12 burners
2. Gas Supply System:
Propane gas pipeline, pressure regulating valve, valves, pressure sensors and other fuel supply systems, used to transfer gaseous propane to the ignition system and the combustion nozzle. The fuel supply system can provide a sufficiently uniform and consistent heat flow rate, with a heat flow density of at least 84 kw/m², and the fuel supply time error is ±0.1s.
3. Safety Assurance System: Gas detector, door seal detector, flame detector, fire extinguisher, emergency stop device and other necessary safety systems.

III. Burning Dummy System
1. The true form and size of the burning dummy are based on an adult male of 1.81 meters in height. The dummy consists of a head, chest, back, abdomen, arms, hands, legs, and feet. The outer shell of the dummy model is made of completely fireproof and heat-stable non-metallic materials (specific specifications can be customized).
2. Heat Flow Sensor  The heat flow sensor is installed on the surface of the model body and can accurately measure the changes in the surface temperature of the dummy. 136 units of DR666-40R type are available. 
IV. Computer Centralized Control System and Application Software Platform
By using the independently developed software system, the entire experimental process is fully controlled by computers, and data collection and analysis are all automatically completed by the computers.
