This free lecture describes a unique method of managing the operation of biomass-fueled, as well as auxiliary, boilers for optimum system performance. It begins with an explanation of why thermal storage is critically important in many systems using biomass boilers. It goes on to describe how temperature stacking is accomplished using multiple temperature sensors mounted in different vertical locations within a thermal storage tank and off-the-shelf controllers. It explains how to use the temperature stacking technique in systems using multiple biomass boilers as well as systems that combine a biomass boiler with an auxiliary boiler.
The lecture covers:
- The need for proper thermal storage in systems using wood-fired heat sources
- The rationale for temperature stacking within thermal storage tanks
- How to configure standard controls to manage temperature stacking
- How temperature stacking differs when using an auxiliary boiler
