Many in the biomass heat industry aim for stratification in (thermal) storage. DCM Logic’s data show that tank stratification is uncorrelated with boiler plant performance, as defined by the percentage of time that the boiler plant is providing the specified water temperature. Also, some boilers spend an average of 45 minutes to 2 hours in fault per day. That’s time when they’re not providing heat. For more information, download DCM Logic’s slides from the 2016 NE Biomass Heating Expo in Burlington, VT.
Are you able to quantify your boiler’s performance? You may know your boiler’s thermal efficiency. High efficiency values usually indicate a low level of particulate emissions. So did you buy a commercial boiler just to have a high-efficiency, low-emissions appliance? We suspect you actually bought it to heat water, and to provide it at a specific temperature. We keep track of how well boiler plants do at that task–we call it Boiler Plant Effectiveness. Check out this presentation to learn some of our ideas on boiler performance. Or if you want to cut to the chase and just see a single slide, take a look at our Boiler Plant Effectiveness Scores slide.
