Abstract
Sposób pomiaru przebiegu emisji gazu w wyniku desorpcji z próbki materiału węglowego polega na tym, że obserwuje się pozycję cieczy znacznikowej w transparentnym kanale pomiarowym, rejestruje się chwilowe wartości emitowanego gazu, wskazywane przez pozycję cieczy znacznikowej w trakcie trwania pomiaru, przy czym za desorbowalną zawartość metanu w próbce przyjmuje się ostatni odczyt, a dla pomiaru przebiegu emisji gazu wykreśla się czasową zależność ilości wyemitowanego gazu oraz interpoluje przebieg funkcją: (A), gdzie: V(t) jest całkowitą masą gazu uwolnionego z węgla w chwili czasu t, V(?) jest granicą do której w miarę upływu czasu zmierza masa uwolnionego gazu, (Rz) to tzw. promień zastępczy ziarna dla klasy ziarnowej:, R1 i R2 to minimalny i maksymalny promień ziaren danej klasy ziarnowej. D* to efektywny współczynnik dyfuzji. Przedmiotem wynalazku jest też analogowy analizator zawartości gazu desorbowalnego i kinetyki emisji gazu z węgla.The method of measuring the course of gas emission as a result of desorption from a sample of carbonaceous material is that the position of the marker liquid is observed in a transparent measuring channel, the instantaneous values of the emitted gas are indicated, indicated by the position of the marker liquid during the measurement, while the desorbable methane content the last reading is taken in the sample, and for measuring the course of gas emissions, the time dependence of the quantity of gas emitted is plotted and the course is interpolated by the function: (A), where: V (t) is the total mass of gas released from coal at the time t, V (? ) is the limit to which, as time passes, the mass of gas released, (Rz) is the so-called grain equivalent radius for the grain class: R1 and R2 is the minimum and maximum radius of grains of a given grain class. D * is the effective diffusion coefficient. The subject of the invention is also an analogue analyzer of desorbable gas content and kinetics of gas emission from coal.
