ZY6264 10MW heat release rate test device
1.Scope of application:
Applicable to buildings and large complexes (including locomotive vehicles, vehicles, warehouses and components) and extensive fire resistance test verification for raw materials, buildings and physical models.
The most basic physical quantity of a large calorimeter is the heat release rate. When a fire, to measure don't know the chemical composition of the raw material of heat, its basic principle is based on the fact that the combustion heat is proportional to the required amount of oxygen, oxygen consumption per 1 kg to generate heat 13.1 million joules. The heat is calculated by measuring the flow of oxygen and the discharge of gases.
The most basic physical quantities are heat release rate, smoke yield, mass loss rate and oxygen consumption, carbon monoxide (CO) and carbon dioxide (C02). The concentration of a specific gas used for heat or selectivity.
3.Meet the standard:
According to ISO 9705 "Fire tests; full-scale room test for surface products" requirements;
Reaction to fire tests-heat release, smoke production and mass loss rate-part 1: Heat release rate (cone calorimeter method) is designed and manufactured in accordance with iso5660-1.
ISO 9705: Fire tests: full-scale room test for surface products
ISO 13784-1: fire response to plywood building systems,
ASTME 1537: standard method of fire test for upholstered furniture
GB/T 25207-2010: solid room fire test method for surface products
Iso05660-1: Reaction to fire test -- heat release, smoke production and mass loss rate (cone calorimeter method)
The heat release rate test device consists of protective cover and pipe system, flow temperature control system, flue gas analysis system and collection system.
1) Protective cover and piping system
When designing a protective cover, there are two main points: the form and size of the protective cover. Compared with a square shield, the round shield can minimize the eddy effect that can occur along the edge of the shield. Therefore, using circular protective cover, adjustable height enables the test to operate according to the characteristics of smoke plume. In addition, the gas can be completely dispersed because the fittings of the pipes and equipment are provided with sufficient uniformity.
2)The outside diameter of 10 cm of dust cover, it can use the maximum range for 10 mw heat meter to measure the actual size of the flammable items and the heat release rate of the vehicle, fire load, oxygen demand (cod), the amount of carbon monoxide and carbon dioxide, concentration, temperature, flow rate and gas composition.
1)Specification of cabinets: height = 1800mm, width = 900mm, depth is greater than 600mm.
Meanwhile, oxygen consumption and carbon monoxide and carbon dioxide production rate were analyzed.
3)The resolution of the gas analyzer is: oxygen 0~ 25%, carbon monoxide 0~ 1%, carbon dioxide 0~ 10%.
Set by-pass for quick response for quick response.
Data acquisition system: dedicated collection system and brand Lenovo computer
6.The size of the main parts
A) Test room: 3.6m (L)*2.4m (W)*2.4m (H)
B) Protective cover: 3m (D)*3m (W)*1.05m (H)
C) Catheter: 0.4m (diameter), 5m (length including guide plate)
D) Sampling probe: 17 holes 2mm, 16 holes 3mm (set in the direction of the sample flow).
