Description
The problems of formation of nitrogen oxides during combustion of organic fuels in the boiler set out in the national and international literature in recent years. Chemical reactions and mathematical models that accompany the emergence of thermal, prompt and fuel NOx are discussed in this article. Impact assessment forms furnace boiler composition of the products of combustion of gaseous fuels cited by the authors

MODELLING OF THERMAL PROCESS OF DRAWING COVERINGS
DescriptionThe article shows that the distribution of temperature regime in EIS corresponds to a known process of cutting and surface plastic deformation with heating details with acetylene-oxygen burner, which allows to combine the process of welding filler powders with finish-hardening treatment with combined instrument in the form of a two-pole bracket

THE FILLING PILE SETTLEMENT PROCESS INVESTIGATION
DescriptionThe filling piles and their joint work with soil are the objects of research. The joint working of filling piles and soil has been researched with the constant rate of loading (CRL) and the continuous measuring of deformations of physical model. The experiment was realized at the physical model of filling pile in soil with the apparatus AKP-6NM. The hypothesis of mechanical working of near-pile soil was proposed as the result of the experiment

Description
The article deals with the basic regulations which allow us to estimate the influence of the velocity variation of wind upon the rotation speed of the windwheel. The method of experimental determination of the inertia of the wind power plant was described. The formulas for the determination were also described

DescriptionAccording to the results of anatomical researches is determined, that under three sides spring punning of roots simultaneous annual applying of regalis number of grown closed (fruit) buds increase about 22–26 % during the first year, but then influence becomes weak and about the fifth year it needs the second (repeated) pruning of roots. Under two-sides pruning of roots a little decrease of size (caliber) is noticed in such sorts of apples as Gala and Golden Delicious
