Utility boilers operate in one of the worst environments in the power business; they warp, they grow, they shrink and they twist. Ports can become clogged with dust and ash or covered with slag. Zolo Technologies' SensAlign and ClearView™ systems are designed to perform in this challenging environment.
No sensitive electronics are located in the measurement heads. Instead, lasers and detectors are installed in the control rack and connected to the heads with fiber-optic cables. Servos in the measurement heads are controlled from the control rack and actuate output and collection optics inside the SensAlign head. As the boiler conditions change, the heads actively maintain alignment for each measurement. Transmitter and receiver heads are identical from a customer perspective; they require no differences in mounting or access.
SensAlign auto-alignment is included on each ZoloBOSS™ transmitter and receiver head and allows measurements across large boilers. Heads located in the combustion zone also include the ClearView port-rodding system to automatically clear a path of dust, ash or slag that may have accumulated in the port. The ClearView system is controlled by the system software and requires no user intervention to operate.
