Pulse ignition device, and open pipe electromagnetic valve 67-69, the burner on entire model bed enters combustion state, makes every
A burner fuel supply reaches 3.6m3/h。
After experiment starts 200s, the pulse ignition device on ceiling on burner 34-42 is opened, and open pipe electromagnetic valve
80-85, fuel enters burner and is ignited, and is gradually increased valve opening, makes each burner fuel supply up to 3.6m3/
H shows model bed body full combustion, the ceiling jet and certain thermal accumlation that ceiling forms above bed body.Hot cigarette
Gas is spread along ceiling, and rate of propagation increases, and the pulse point on ceiling on burner 43-51 is opened when experiment starts 220s
Fiery device, and pipe electromagnetic valve 86-94 is opened, and be gradually increased valve opening, reach each burner fuel supply
3.6m3/ h shows that entire cabin ceiling has accumulated amount of heat, progresses into combustion state.
Experiment starts 400s, opens the pulse ignition device on burner 52,53, and open pipe electromagnetic valve 70,72, and
It is gradually increased valve opening, makes each burner fuel supply up to 3.6m3/ h shows that hot fume sedimentation and indoor heat have collected
Gather to a certain degree, simulation thermoradiation efficiency generates sofa and heat and start combustion phenomena, small sofa and couch are locally opened
Begin to burn, open fire begins to extend on couch, and flame spread rates are about 2.5cm/s.And it is opened respectively in 410s and when 420s
The pulse ignition device on burner 54,55 is opened, and opens pipe electromagnetic valve 78,79, ignite other two burner of couch,
And it is gradually increased valve opening, make each burner fuel supply up to 3.6m3/ h shows that entire couch has caught fire.
When experiment starts 550s, the pulse ignition device on the ground of cabin on burner 56-63 is opened, and opens pipeline electricity
Magnet valve 71,73-77, and it is gradually increased valve opening, make each burner fuel supply up to 3.6m3/ h, shows in 550s
Interior has reached the state of flashing over, and the unexpected occurrence of large-area burning of room floor, entire room includes floor, model furniture and day at this time
Card is in fierce combustion state, and has amount of heat and flue gas to overflow from hatch door.
When experiment starts 720s, fuel supply valve is closed, to indoor fuel gas afterburnt end simulation lecture experiment.At this time
After opening exhaust fume collecting hood exhaust fan about 10min excludes outdoor from indoor to flue gas completely, and room temperature is down to 40 DEG C or less, mould
Quasi- lecture experiment terminates, and personnel can be allowed to enter.
This experimental provision carries out cabin fire spread in simulation room and flashes over the reality of phenomenon using natural gas as combustion medium
Test simulation.Experimental provision is integrally made of steel construction, has vdiverse in function, simple structure, high reliablity, easy to clean, cost
