In the article analysis of the existing methods of calculation of temperature of a steel liquidus is made on the basis of which the option providing results with the minimum error of experimental data is chosen. To define the metallurgical length of the ingot spilled in the conditions of the of continuous casting machine and time of full solidification of a metal new assessment technique is offered; existence of clusters in liquid melt and a liquidation of impurities in the course of crystallization is taken into consideration.

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.

The paper contains a comparative efficiency analysis pertaining to application of existing technological methods for suppression of nitric oxide formation in heating boilers of heat generators. A special attention has been given to investigation of NO x emission reduction while burning hydrocarbon fuel with the help of oxygen-enriched air. The calculations have demonstrated that while enriching oxidizer with the help of oxygen up to 50 % (by volume) it is possible to reduce volume of NO x formation (while burning fuel unit) by 21 %.
