KF300 Online Gas Monitoring System
Product Description
The KF300 Kiln Inlet Online Gas Monitoring System from Kelisaike Safety is a high-performance solution designed specifically for the
demanding operating conditions of cement plants. Using advanced
heated extraction technology and a specialized QT100 sampling probe, it delivers accurate, real-time analysis of key gaseous
pollutants such as CO₂, CO, NOx, SO₂, and O₂—directly from the kiln
inlet, decomposition furnace, or preheater outlet.
Engineered for extreme environments, the KF300 operates reliably in
flue gas temperatures up to 1,200 °C and dust concentrations of 2,000 g/m³, while withstanding corrosive gases such as SO₂. The pretreatment system features imported components to resist water, dust, corrosion, and
clogging, ensuring continuous operation with minimal maintenance.
The integrated WT300 multi-gas infrared analyzer supports up to five gas channels with high measurement accuracy, rapid response time (<25s), and
versatile data outputs including RS232/RS485 (Modbus) and 4–20 mA
analog signals. Combined with the BRG100 heat-tracing sampling pipe, the system maintains sample integrity even in low ambient
temperatures or humid conditions.
Automation is at the core of the KF300 design, featuring automatic
sampling, purging, calibration, fault self-diagnosis, and alarm
functions. This reduces manual intervention, lowers operational
costs, and ensures consistent data quality for process
optimization, safety assurance, and environmental compliance.
With its robust construction, intelligent control software, and
industry-proven sampling technology, the KF300 is the ideal
solution for cement producers seeking to improve clinker quality,
reduce fuel consumption, and meet strict emission standards—all in
one integrated system.
