Thermal oil biomass boiler dynamics as a part of the micro-CHP ORC plant

The aim of the paper is to present the results of experimental research conducted on two helical coil biomass boilers with oil heatingagent, which are acentral unitsof co generative micro powerplant designed and built in IFFM in Gdańsk. Experimental data served as a source for defining the interdependencies governing the dynamics of the micro-CHP as a whole. Furthermore, during the research the authors came across a few possible modifications to the construction that may yet improve the device.
