Monitoring of coal powder flow status in GPS gasification furnace pneumatic conveying – solid flow meter

Thread Content

The GPS gasification furnace is not widely used in China, but within the entire system, the flow rate of coal powder in the two pneumatic conveying systems plays a crucial role in the overall operation of the system. Traditional monitoring methods cannot provide feedback on real-time conditions; in such cases, the advantages of solid flow meters become particularly evident, as they can deliver actual feedback on the instantaneous condition, unaffected by the air pressure within the pneumatic conveying system. The German viscosimetric solid flow meter will be discussed in detail below. The MIC sensor uses the current* best processors. Microwave solid flow meters can measure the flow rate of bulk materials in pipelines in a contactless and maintenance-free manner. The measurement probe is made of V4A material, with a ceramic sensor tip. The high-temperature version can reach 200 degrees. No separate electronic device is required. When calibrating the sensor on a computer, the signal curve is displayed graphically on the computer screen. . Technical advantages • Contactless measurement of the flow rate of bulk materials in pipes ； •The temperature of the measuring probe can reach 200°C ； •Program settings are carried out via the USB interface ； •Standard application range DN50—DN300 ； •Calibration through the customer interface ； •On/off flow version with switch output ； •Probe lengths of different lengths ； •MOD-BUS interface ； •CAN-BUS interface. The front end of the waveguide emits a wave toward the measurement medium at a frequency of around 24 GHz, with a power consumption of less than 5 milliwatts. A single material particle in a microwave field reflects a pulse spectrum. Pulse fronts are formed when entering and leaving the microwave field; these pulse fronts can be calculated using special algorithms, and thus are proportional to the mass flow rate. The current flow value and transmission speed value are output via a 4-20 mA signal. A pulse output is provided, with the output value in terms of mass in kilograms being defined in advance (for example, 1 kilogram, 10 kilograms, or 100 kilograms correspond to one pulse). The housing material is cast aluminum; the protection rating is IP66. The probe head is made of V4A ceramic. Dimensions: probe head – 115 x 90 x 82 mm; probe shaft – 150 x 19 mm / 250 x 19 mm. Power supply voltage: 20–28 VDC; there is a fuse built in, with a current consumption of 400 mA. Input and output signals: 1 x 4–20 mA, with 0–20 mA as an optional option. 1 x relay output for pulse generation. Environmental conditions: Operating temperature outside –10°C * +55°C. Operating temperature inside the tube: 150mm probe –10°C to 70°C ； 250mm probe –10°C to 120°C. Pressure inside the tube: *20 bar higher. Weight: 2,150 g. Accuracy varies depending on environmental and installation conditions: +/- 3-5%. ● Used for measuring the quality, concentration, and flow rate of coal powder in blast furnaces for iron production ； ● Coal feeding in power plant boilers, measurement of coal powder quality, concentration, and flow rate ； ● Activated carbon flow monitoring for waste incineration power generation in power plants ； ● Detection of pollutant emission fluxes from incineration plants ； ● Measurement of limestone powder flow rate during pneumatic conveying ； ● Free-fall quicklime flow measurement ； ● Free-fall solid grain flow measurement ； ● Free-fall salt particle flow metering ； ● Free-fall cornmeal flow metering ； ● Measurement of powder flow rate during free-fall section ； ● Sodium phosphate flow monitoring ； ● Potato chip seasoning powder flow monitoring and dosage distribution ； ● Monitoring of dust emission concentrations from various fuel boilers, etc. Solid flow measurement in pneumatic conveying pipelines for power plants.
