The Combustible Heat Release Rate Cone Calorimeter measures the heat release rate of a material based on the oxygen consumption principle. The oxygen consumption principle states that a material releases essentially the same amount of heat per unit of oxygen consumed during combustion. When a sample is exposed to the heat source of a cone heater, the Combustible Heat Release Rate Cone Calorimeter measures the sample’s heat release rate, smoke generation, oras ng pag aapoy, oxygen consumption, carbon monoxide and carbon dioxide production, and mass loss rate. This device provides an adjustable oxygen concentration atmosphere to simulate combustion characteristics under various conditions, meeting the requirements of scientific research and specialized experimental scenarios, and is widely applicable in various fields.

Product Features

The chamber utilizes a modular frame structure with an independent gas analysis cabinet and combustion test platform to minimize the impact of fan vibration on test data and ensure stable and reliable test results.
The test bench area is equipped with a tempered glass observation window for observation and protection during testing, and an explosion-proof steel mesh is installed underneath.
The test platform features a marble worktop for high flatness, thermal insulation, and an elegant appearance.
Three test platforms are available: horizontal and vertical radiation cone calorimetry test platforms that meet ISO 5660-1, ISO 5660-2, BS 476 Bahagi 15, GB/T 16172, and ASTM E1354 standards; a combustion test platform with radiation cones and larger specimens that meet ISO 5660-4 and ASTM E2965; and a calorimetry test platform with adjustable spatial concentration that meets ISO 5660-5.
Two sizes of radiation cones are available based on test requirements. The cones feature a stainless steel housing with insulation between the inner and outer covers. The heating wire temperature is measured using a K-type thermocouple, and the cone’s heating output is adjusted using a power regulator and temperature measurement module. Power ratings are 5 kW and 15 kW, respectively. The cones are highly engineered and have a long lifespan. The small cone provides irradiance ranging from 0 sa 100 kW/m2, while the large cone provides irradiance ranging from 0 sa 120 kW/m2.
The cones utilize a thermopile heat flux meter and are equipped with a portable water cooling system, allowing real-time monitoring of cooling status on the panel. Automatic calibration of the radiant cone heating power allows for convenient and quick radiant illumination.
The weighing device utilizes a Siemens weighing module with a sensor range exceeding 6000g and a display accuracy of 0.01g.
Two sizes of stainless steel test platforms and sample boxes are available, suitable for testing samples measuring 100mm*100mm and 160mm*160mm, respectively. They are resistant to radiant heat and the high temperatures of sample combustion. A height adjustment mechanism allows for adjustment of the test position for both standard and foamed samples.
Standard calibration weights are provided for calibration of the weighing system.
The sample is ignited using a high-voltage pulse spark plug with an ignition voltage of 10kV.
A brass calibration burner with a clip-on mounting generates a flame for calibrating the orifice plate coefficient C.
The calibration burner uses an MFC flow control with a range of 10L/min, an accuracy of ±1% F.S., a linearity of ±0.5% F.S., and a response time of ≤2 seconds.
Equipped with a high-flow, adjustable-concentration sealed enclosure, the oxygen and nitrogen MFCs have a range of 0-200 L / min, enabling the setting and adjustment of an oxygen concentration atmosphere from 0-30%.
Equipped with a stainless steel fume hood and exhaust ducting, these units meet standard requirements.
A multi-blade centrifugal blower with an inverter allows for stable air velocity and flow rate regulation.
Imported thermocouples are used to monitor the temperature within the exhaust duct, with a measurement accuracy of ±0.1°C.
The thermocouples are connected to the duct with a ferrule-type connection, making them easy to install and disassemble.
An orifice plate differential pressure mechanism measures air pressure, with pressure gauges located on either side of the orifice plate.
An imported micro-differential pressure transmitter converts and outputs pressure signals.
An imported laser transmitter and silicon photodetector are used to measure smoke concentration changes within the duct.
Standard filters are provided for calibration of the optical system.
A brass ring sampler is built into the smoke sampling duct to collect test smoke. The sampling hole faces away from the wind flow to prevent clogging by combustion dust.
The sampling probe is connected to a sampling pump via a PP hose, which draws sample gas and transports it to the gas pretreatment system. The sampling pump has a pumping capacity of 36 L / min, an operating pressure of 7 kg (0.7 MPa), an operating vacuum of -93.1 kPa, and a flow rate of 36 L / min (50 Hz).
The gas pretreatment system consists of a filtration system, a gas cooling system, a gas dehumidification and drying system, and a gas conditioning system.
It is equipped with a three-stage filtration system. The first stage uses a cartridge-type coarse filter system to filter larger particles from the flue gas and prevent clogging of pipes and joints. The filter element is replaceable. The second stage uses a cup-type protective filter to filter particles larger than 0.5 M. The filter element is replaceable. The third stage uses a membrane filter to filter particles larger than 0.2 M.
The cooling system uses a condenser and a peristaltic pump for condensation and water removal. The condenser features dual-circuit cooling, with a stable dew point of approximately 0.1°C and an outlet gas temperature of approximately 5°C. The peristaltic pump outlet is equipped with a condensate collection box with an internal sponge.
The dehumidification and drying system uses DRIERITE anhydrous calcium sulfate placed in the air filter tube to remove moisture from the test gas, ensuring the dryness of the gas entering the analyzer. The anhydrous calcium sulfate changes color after absorbing water, making it easy to observe and replace.
Analysis/Calibration Switching Unit: The analyzer cabinet panel features quick-connect plugs for the sample and calibration gas inlets. High-reliability ball valves and three-way switching valves are used for easy on-site calibration and maintenance.
Quick Bypass: A panel-mounted Dwyer rotor flowmeter is used for sample gas bypass evacuation, ensuring a sample gas flow rate of 3.5 L/min entering the analyzer.
Pressure Regulator: A pressure regulating valve is used for pressure regulation, adjustable between 0 at 0.4 MPa.
Professional HRR gas analyzer, including O₂, CO, and CO₂:
