1.3 Product Overview
The sequencer panel is fitted into a metal industrial electrical cabinet, with a touch screen HMI on the
outside. It is designed to monitor the functions of multiple boilers that are working on the same system,
monitoring normal occurrences such as pressure and flow rate - also errors, faults and alarms.
The sequencer panels purpose is to ensure the boilers are ready for process normally when left overnight so
they don’t fully cool down and can be safely and gradually brought to temperature/pressure. This is because
in normal operation, the boilers be will be powered up quickly when required, if this is done it can cause
fatigue on the boilers and will also cost more money due to the added energy of start-up.
Optional slow opening steam valves can also be installed after the boilers, these will gradually open when
slowly powering up, this will allow the steam system to slowly re-pressurise. This is an advantage because in
a lot of cases as many boiler locations being quickly powered up, the pressure is released very quickly from
the boilers, this causes the condensate within the system’s pipework to be transported through it very
quickly (water hammer) which can lead to significant damage to the system, potentially health and safety
risks and very loud and uncomfortable noises within the system.
The sequencer also automatically switches which boiler(s) (depending on how many are fitted and steam
demand) are taking the lead, which are assisting, and which are in reserve (banked); this will help to ensure
that they are evenly utilised over their life. The SCOPE sequencer panel will also automatically change a
boiler from assist or reserve up to lead or assist with an increased steam demand, so manual intervention is
not required. It will do the opposite in a low demand situation from a high demand. It can also change a
boiler over to a new lead or assist if the current lead or assist is in an alarm situation to ensure seamless
supply of steam, providing of course, that the remaining boilers can cope.
The SCOPE Sequencing panel has optional extras that can be utilised such as controlling of valves after
boilers, hotwell and boiler room temperature monitoring and feedback to BMS central system.
