Abstract:
The paper presents experimental results of laboratory research. Tests were done on several hundreds of pieces of pellets made of wood (forest waste), sunflower hull, straw and wheat bran. These types of pellets are most commonly used for co-combustion in Polish power stations. The measurement stand enabled testing of influence of air humidity, air temperature and air flow speed on moisture permeation rate in single granule of each type of pellets. In a limited way a change of spatial moisture contents distribution in time in a single granule is determined and depicted. The test results allowed for determination of resistance to moisture permeation of each type of pellets. Two potential definitions of moisture permeation resistance coefficients are elaborated. These are: change of moisture contents after 5 hours (in defined climate conditions) and change of moisture contents in comparison to a standard change of moisture contents of pine sawdust pellet after 5 hours (in defined climate conditions).
