The One

A system for burning of a destroyed highly toxic substance with formation of a vertical supersonic stream of combustion products moved away to the atmosphere on considerable heights has been considered. A technique and an algorithm for conjugated gas-dynamic and thermodynamic calculation of working processes in two-zonal unit with primary burning using air in a camera similar to the one of a liquid rocket engine, and after-burning in a supersonic flow have been proposed. The technique has been approved on the examples of after-burning mathematical modeling and a parametrical research on combustion completeness influence on composition and properties of products resulting from heptyl combustion in air with after-burning in case of methane supply in the second zone.

The method of fuel quality control is considered, which is based on the using of the oxygen sensor (without sensors of incomplete fuel combustion products). An algorithm for the electric drive of a fan is proposed, which is based on a step changing in the rotation speed. The choice of broadband oxygen sensor as a basis for the development of a fuel combustion control system is determined. In the course of experimental studies, the possibility of reconstructing the boiler by replacing a burner with an installed control system was demonstrated. The commissioning works were carried out with the installed system, the optimum operating conditions of the boiler were determined (with the formation of CO in the flue gases at a minimum level <50 ppm). The technical characteristics of the boiler operation under different loads (from 10 % to 100 %) are considered. Ecological and economic analysis of the developed fuel combustion control system was carried out.
