Boiler Fire Safety System

HmT Mechatronics were contacted by Sondor to add extra safety to their existing system, they wanted us to detect whether there is a burst pipe or a fire in the room where there oil burners are situated, whenever one of this parameters are true, the entire system should shut down and give a fault indication.

HmT decided to install a small PLC to monitor some fuse links that is mounted on top of the burners to detect when there is a fire present. Four pressure transmitters were also installed to detect a drop in pressure on the supply and return oil pipes, any pressure drop in the pipe would mean that the pipe has burst or is leaking. When the PLC reads that any of these conditions is true it will shut off the supply of the oil, thus preventing a major fire.
