GJCFB-15 Power plant boiler air preheater system Bellows is a device used to measure the clearance of boiler air preheater. Its design principle is to calculate the size of the gap by measuring the pressure and temperature inside the preheater.

Specifically, the transmitter consists of two sensors: a pressure sensor and a temperature sensor. These sensors are installed at the inlet and outlet of the preheater to measure the pressure and temperature at the inlet and outlet. In addition, the transmitter also includes a microprocessor to calculate the size of the gap and output the corresponding signal.

In operation, air flows through the preheater past pressure and temperature sensors. These sensors pass the measured data to the microprocessor, which calculates the size of the gap by comparing the difference between the inlet and outlet pressure and temperature. The calculated gap size will be output in the form of electrical signal for recording and processing by the monitoring system.

In general, the design principle of the GJCFB-15 Power plant boiler air preheater system Bellows is based on the measurement of the internal pressure and temperature of the preheater to calculate the gap size. The application of this equipment can help maintenance personnel to detect and repair the preheater gap in time to ensure the normal operation of the unit.
