Building Materials Monomer Combustion test Dust Removal Equipment
The Dust Removal Equipment for Single Burning Item (SBI) Testing is designed to collect and filter smoke and dust generated during single burning item tests of building materials and products. It helps reduce particulate emissions from the test exhaust while minimizing interference with the exhaust airflow required by the combustion test system.
The system uses a cartridge filtration design with high-temperature-resistant, electrostatically coated filter media. A pulse-jet cleaning mechanism removes accumulated dust from the filter cartridges, while a Siemens PLC control system manages the sequential cleaning process. A high-power exhaust fan controls the flue gas flow through the system.
With an exhaust capacity of 2,400 m³/h, nine filter cartridges, and a total filtration area of 45 m², the equipment is intended for laboratories conducting SBI fire performance tests on building materials and products.
Application
(1) Building material single burning item (SBI) testing laboratories.
(2) Smoke and dust filtration for combustion test exhaust systems.
(3) Fire performance testing facilities for construction products.
(4) Laboratories conducting reaction-to-fire evaluation of building materials.
(5) Fire testing facilities requiring controlled exhaust flow and particulate removal.
