In this study, we primarily examined the impact of air humidity on the quality and calorific value of wood charcoal and briquettes for grilling. We used Slovenian wood charcoal from Kmetija Frece and Forest Premium brand wood charcoal briquettes. Wood charcoal and wood charcoal briquettes were divided into four separate samples, which were stored at four different locations: in a woodshed, outside under the balcony of a residential building, in an unheated, insulated garage, and in a boiler room. The samples were monitored daily by weighing. Temperature and air humidity were also automatically measured at the storage locations. After a 14-day measurement period, the samples were ignited to obtain data on ignition temperature and burning time. A portion of the sample was also used to analyse water content and calorific value. The highest water content was found in samples of wood charcoal and wood charcoal briquettes exposed to the highest air humidity, while the lowest water content was found in samples exposed to the lowest air humidity. Samples with higher water content also had lower calorific value and ignition temperature. Wood charcoal briquettes exhibited a higher hygroscopic capacity, which likely affected their ignition ability (samples exposed to higher air humidity did not ignite). Despite the same storage conditions, wood charcoal maintained a higher calorific value compared to wood charcoal briquettes. The results of this study emphasise the importance of proper storage of wood charcoal and wood charcoal briquettes in dry and warm environments, as this ensures optimal energy efficiency and sustainable use of these energy sources.
