“…As a result of experimental research (Pylypchuk, Hryhoryev & Shostak, 2007;Lys & Mysak, 2012) using B-plan (В 3 ) dependence of the net calorific value of synthesis gas ( р н Q MJ/m 3 ), for the process of wood gasification on such factors as: size of the wood particles l = 10, 30, 50 mm; amount of air G = 40, 65, 90 nm 3 /hr; amount of fuel in the gasifier reactor q = 50, 75, 100 % has been established. Calculation of the regression coefficients b ij , Cochran criterion G р and Fisher criterion F р (Mysak, Lys & Martynyak-Andrushko, 2017;Lys, 2017) for pine wood are provided in Table 2.…”
