Frequency converter for Fans - Frequency inverter

Frequency converter for Fans. A frequency inverter is known by many names, such as variable frequency drive, frequency converter or adjustable speed drive. All mean essentially the same thing: an electronic device that provides stepless speed control in an electric motor. However, today's frequency inverters also feature other functionality, including control and protection to other equipment in the system.

Research on the failure of the induced draft fan's shaft

Boiler interlock isnt a physical control device. Instead it describes how the system has been wired in. Its a wiring arrangement that prevents your boiler from heating your home when theres no need for it, for example, if the temperature that you set on the thermostat has been reached. Without interlock, the boiler would be on continuously, which could waste a lot of energy.

The FD fan solution also demands a boiler/scrubber control system safety interlock. Safe operation of the boiler requires integration of some of the scrubber status signals (e.g. uptake and bypass damper position) and pressure measurement (K61). Likewise, safe scrubber operation requires status signals from the boiler (e.g. boiler load).

The Burner Management System is essentially an interlock switch which permits firing of a boiler at any load and shuts down the fuel sources shall unsafe process conditions occur. BMS also goes by different names. In my previous power plant, it is called as FSSS or Furnace Supervisory Safeguard System which does the same duty.
