High Accuracy & Durability

Walsn CEA - 100 combustion efficiency analyzer is designed to continuously monitor CO content in flue gas while the measurement data can be used to adjust the ratio of fuel/ air so as to achieve the maximum boiler efficiency for boiler operation. Walsn CEA - 100 adopts the dual-measuring-sensor technology and features high accuracy with low zero drift and very small failure rate, matching the requirements of the harsh industrial environment. It is also easy to install and maintain.

FSE-100 Explosion-proof Flame Detector is used to collect the flame signal which is amplified and processed to determine the presence or absence of flame，integrating with  ultra-violet (UV) and infra-red (IR) sensors. FSE-100 Flame Detector provides the flame output in real-time – the basis of determining the presence or absence of flame. The detector is suitable for both oil and coal fired applications.

FS-100 utilizes SMT technology which integrates a photoelectric sensor, a microprocessor, and a Human-Computer Interface (HCI) and an output interface together, sending out various outputs including an ON/OFF flame signal, a fault signal, a 4-20mA signal, and an RS-485 output (meets the MODBUS standard) via the quick connector.

Walsn Mill & Silo Monitoring system (MSM-100) is specifically designed to continuously detect carbon monoxide (CO) in pulverizing mills. This system has been developed to detect high levels of CO, produced by any incomplete combustion, effectively giving advance warning of a potential mill fire.

The acid dewpoint of a flue gas is the temperature, at a given pressure, at which any gaseous acid in the flue gas will start to condense into liquid acid.

FDS-600 Remote Flame Detector consists of two units：FDS-601 flame detector and FDS-602 control unit.

Energy conservation and emission reduction are the two main themes of coal-fired power plants. To optimize combustion, it is necessary and important to add pulverized fuel (PF) flowmeters and flow control and balancing devices for boiler combustion, both to ensure combustion efficiency and to meet the requirements of low NOx emission.

For boiler combustion, controlling the CO level of flue gas can reduce incomplete combustion and the heat loss to the exhaust gas. This is due to the fact that the CO level of flue gas reflect the burning condition inside the furnace. When the furnace burning condition is not optimal, there will be coking, high temperature corrosion, or flue gas temperature deviation, resulting in boiler safety problems. It has therefore become important and necessary to detect and control CO level in the flue.
