The stopping sequence of the above boiler auxiliaries should be in the reverse order of the starting sequence. The failure of any equipment in the above order should cause immediate stop of all succeeding equipment. Selective interlocking should ensure that with only one of the two ID fans running one FD fan could be operated.

Combustion Air Requirements:The Forgotten Element In

In 1905, the Grover Shoe Factory boiler exploded, collapsing the building and engulfing it in flames. Fifty-eight people were killed and 150 more injured. This event led to the development of safety laws and a national code for the safe operation of steam boilers. The CB-Hawk boiler management control system (''Figure 1'') combines the functions of

Hot Water Heating Boiler Operation Details - 39 steps in

A boiler/scrubber control system safety interlock is necessary. 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). Main engine Auxiliary engine
