Stable Furnace Structure
Frame-type furnace body with refractory bricks and high-temperature insulation fiber ensures thermal stability while minimizing heat loss to the surrounding environment.
Safe and Practical Platform Design
Steel platforms are installed around the furnace to facilitate operator movement and on-site inspection.
Automatic Flame-Out Protection
If a burner extinguishes unexpectedly, the control system immediately triggers visual and audible alarms and automatically cuts off the LPG supply to the affected burner while allowing other burners to operate normally.
Comprehensive Gas Supply Control
Equipped with gas solenoid valves, proportional valves, ball valves, and gas transmitters to ensure accurate gas flow control and operational safety.
Optimized Combustion Air Control
Combustion air is supplied by a dedicated blower with frequency control to maintain an appropriate air–fuel ratio.
Independent Control System
Dedicated control components are used to manage combustion processes and accurately simulate standard fire curves.
Automatic Temperature Curve Correction
The actual furnace temperature curve is continuously compared with the preset curve, and deviations are automatically corrected through burner output adjustment.
Complete Data Storage
All automatic control and test data are stored in the computer system for traceability and accuracy verification.
(1) Proportional flat-flame burners
(2) Gas solenoid valves and proportional valves
(3) Combustion air blower with frequency inverter
(4) Gas pressure regulators and filters
(5) Exhaust duct with refractory brick structure
(6) High-temperature exhaust fan with inverter
(7) PLC-based control system
(8) Computerized data acquisition and monitoring system
Install the vertical test specimen securely on the steel test platform according to the relevant standard.

1. What types of building elements can be tested with this vertical furnace?
This furnace is suitable for fire resistance testing of non-loadbearing vertical partitions, fire doors, and fire shutters. It supports standardized testing in accordance with GB/T 9978 series standards, ISO 834. and EN 1363. allowing evaluation of integrity and fire exposure performance of vertical separating elements used in buildings.
2. How does the furnace ensure accurate temperature control during testing?
The furnace uses a computer-based control system combined with PLC and intelligent instruments to continuously monitor furnace temperature through multiple thermocouples. The actual temperature curve is compared with the preset standard fire curve in real time, and burner output is automatically adjusted to correct any deviation. This ensures that the furnace temperature and its distribution meet the strict requirements of fire resistance testing standards throughout the test duration.
3. What safety protections are included in the combustion system?
The system includes automatic flame-out detection, visual and audible alarms, automatic gas shutoff for extinguished burners, pressure relief devices, and explosion protection measures to ensure safe operation during high-temperature testing.
4. What type of fuel gas is used by the furnace?
The furnace uses liquefied petroleum gas as the combustion fuel, providing stable and controllable heat output for fire resistance testing.
