In the Pulverized Coal Boiler, the coal pipes layout are varies and each coal pipes has a different length and layout to the burner.
With the nature of flow loss and resistance, the coal flow will be uneven distributed among different pipe levels to the burner.
However, without a visibility to monitor the coal flow and coal velocity online or continuously, the plant user could not optimize the coal flow balancing.
In order to address this, TECG provides the Online Coal Flow Monitoring and Balancing Solution.
TECG Control offers the unique coal flow monitoring system.
The Advanced Coal Flow System is especially developed to measure pulverized coal distribution to each burner. This helps balance particulate coal amount in order to avert combustion issues caused by high LOI results.
COAL MASS FLOW METER & COAL FLOW VELOCITY METER
Massflow Meter is a microwave based mass flow transmitter. The electronic is mounted in the sensor head. The wave guide is made of stainless steel. It is leading the microwave into the pipe. In the front is an antenna that is protected by a special wear protection ceramic.
After Balancing – coal mass flow difference below 10%
TECG Control also provide the Purposed Design – COAL Diffusing Valve for the coal flow balancing. It can effective reduce the coal roping effect and balance the coal flow for different burners.
