Thermal flow switchWhat are the applications of?
1. Measurement of air entering the coal mill
The measurement ensures that coal powder particles of appropriate size enter the boiler. The high air flow velocity causes coal powder with excessively large particles to enter the furnace and cannot be fully burned. The low air flow velocity leads to coal powder particles that are too small, increasing the energy consumption of the coal mill, while also increasing insecurity and difficulties in coal powder storage. The accurate flow rate of air can be reliably controlled by applying a thermal flow switch. Measure the airflow of high-temperature air and cold air. Allow temperature mixing and control to calculate changes in fuel humidity. Prevent the combustion and explosion of coal mills, avoid endangering personal and equipment safety, and prevent boiler shutdown.
2. Measurement of Combustion Air and Preheating Air
To ensure that boilers, furnaces, and waste heat power generation equipment can operate at maximum efficiency, availableThermal flow switchMeasure the air flow rate on a single combustion air and preheating air conveyor line. Improved fuel/air ratio, reduced unburned carbon, and lowered smoke emissions. The reduction of unburned carbon ensures the quality of ash. Helps to improve combustion efficiency and increase equipment lifespan.
3. Smoke emission CEMS
Reliable flow measurement is required for emission chimneys in power plants, waste heat power plants, chemical plants, paper mills, and other industrial manufacturers. This measurement requires a high level of accuracy in calculating the total emissions. The thermal flow switch can be used alone or in conjunction with other systems. In China, in order to meet the requirements of environmental protection, the total emission control of flue gas (CEMS) has been widely used in the renovation of many power plants. FCI's plug-in flowmeter is a reliable measuring instrument in flue gas monitoring and an effective way to measure large pipe diameters and large flow rates.
4. Balance and air leakage control of flue gas/dust collector
useThermal flow switchMeasuring and balancing the flue gas flow through the dust collector, monitoring the air volume entering and leaving the dust collector, can greatly improve the efficiency of industrial pollution control systems. The range ratio of 1000B1 enables FCI's thermal flowmeter to have high accuracy over a wide flow range. The flowmeter has a simple structure, no moving parts, fully welded structure, plug-in installation, and minimal pressure loss in the pipeline. The probe is wrapped with an anti-wear layer to protect it from dust and other particles, and has strong resistance to harsh environments.
5. Monitoring of hydrogen gas flow rate
The steam turbines in power plants generally use hydrogen as the cooling material. If hydrogen gas leaks, it will bring great safety issues. Thermal flow switches warn operators of leakage issues by detecting an increase in flow, and power plants also need to measure hydrogen usage in order to settle with hydrogen suppliers. Usually usedThermal flow switchSimply install FCI's GF series quality flow meters at each point to determine their respective flow rates. Its sensitivity to low flow is superior to other flow meters.
6. Measurement of superheated steam
Used for measuring the settlement of superheated steam output to achieve material balance. Capable of withstanding high temperatures above 450e, maintenance free, and reliable operation. Steam flow measurement has always been a difficult point. Traditional orifice flow meters measure steam flow, and their high pressure loss is a great waste of energy. The plug-in installation of thermal flow meters has almost zero pressure loss.
7. Application of hydropower stations
In the application of water cooling protection for steam turbines in some hydropower stations, the use of thermal flow switches to detect the flow of cooling water has improved the safety guarantee for the reliable operation of the equipment.
