M2G Advanced Boiler Load Control System is specifically designed to eliminate boiler nusiance activity …
- dry cycling
- short cycling
- boiler response to hydraulic short circuiting
These predictible nuisance activities occur at very low load conditions and are very wasteful of energy leading to increased fossil fuel bills, associated Co2 emissions and un-necessary wear & tear and maintenance on expensive boiler plant.
M2G can be applied on all boiler types e.g. forced draught, atmospheric, single and 2-stage including condensing and modulating boilers, and oil fired boilers but not steam.
In and Out
Eliminate Nuisance Boiler Activity
What is dry cycling?
The boiler fires to reach its set point, meeting the building’s heating demands (load). Once the set point has been reached the boiler stops firing.
However, standing heat losses continue and the boiler cools down without transferring this heat to the system load. The boiler will then fire unnecessarily to recover these losses even though the building requires no heat.
Additional Heat Loss
The heat loss is exacerbated when the boiler enters a pre-purge before the next firing to remove any residue of combustible gases.
This is effectively blowing cool air across the combustion space therefore cooling the boiler down before it begins to re-fire.
Continuous Dry Cycling
Dry cycling occurs throughout the year, even if the boilers are just providing hot water generation during the summer months.
Boilers will fire unnecessary to recover standing losses resulting in wasted fuel consumption, costs and CO2 emissions.
