Journal Title: Енергетика і автоматика - Year 2018, Vol 0, Issue 4
Abstract
The purpose of the work is an txperimental determination of the heat of phase transformations in calorimetric studies. The theoretical and experimental part of calorimetric research was carried out on the basis of the basic arrangement of a calorimetric bomb, the determination of the highest heat of combustion by a bomb for analytical fuel sampling according to GOST 147 - 95 (ISO 1928 - 76), GOST 10062 - 75, DSTU ISO 1928: 2006 with subsequent recalculation of it on the lower heat of combustion, the determination of the heat of phase transformation. The technology of determining the quantitative index of phase transformations in determining the calorific value of bio-objects is presented. It has been determined that for moist materials (experimental samples of straw litter No. 1- 3) for which the humidity lies in the range from 23 to 27 %, the quantitative index of phase transformations is in the range from 3580 to 3690 kJ/kg, the percentage of phase transformations, namely the transition in the phase of condensation requires at room temperature from 33.83 to 41.45 % of the theoretical net calorific value. The percentage of phase transformations is very high for very moist materials (experimental specimens of the litter No. 4, chicken egg No. 1, 3,6) and ranges from 80,65 to 84,66 %, and for samples of chicken litter no. 2, 4, 5 not even it has its own calorific value for the implementation of phase transformations.
