Data on complex experimental and theoretical investigations pertaining to efficiency of oxygen-enriched draft in the small-capacity heating boilers as exemplified by the plant HEIZA (HW-S-10/K) have been presented in the paper. The paper provides a calculation model of heating processes in heat generator burner (as exemplified by HEIZA plant). Simulation of heating processes in the operational zone has been executed in paper. The experimental data have proved model adequacy. The calculation scheme of the plant will be used in future for determination of power and ecological efficiency of draft enrichment with oxygen.

Annot For finding-out of a role of separate groups of polyphenols in realization hepatoprotective properties of maksar we investigate activity of polyphenolic complexes (PPC) from duramen and cellular culture of maakia amur. Experiments are carried out on 40 not purebred white rats with an experimental СCl4-hepatites. Therapeutic efficiency of researched objects estimated on their influence on survival rate of animals, morphological and biochemical parameters of a liver and wheys of blood. In rat's CCl4-hepatitis PPC from duramen and cellular culture of maakia amur reduce the acute toxity of tetrachloromethane, decrease the necrosis of hepatocytes and cellural infiltration of liver's parenchyma, prevent from development of fatty and protein dystrophy of a liver, normalize the activity of amino transferase, -glutamyltransferase in blood, the concentration of proteins and lipids, stimulate conjugation of bilirubin. The therapeutic effect of PPC of cellular culture is more evident. The hepatoprotective action is caused by a presence of isoflavonoids daidzein, retuzin, genistein, afromozin, formononetin, orobol, tektorigenin, maakiain and medicarpin. PPC from a culture of cells doesn't influence on a level of cholesterol in blood, that apparently is caused by an absence of mono- and dimeric stilbenes in its structure.
