Solubility in the NaClO3 · 2CO(NH2)2-NH2CH2CH2OH-H2O system

The solubility in the NaClO₃ · 2CO(NH₂)₂-NH₂CH₂CH₂OH-H₂O system was studied over the range from the complete solidification temperature (−54.8°C) to 60°C. A polythermal solubility diagram was constructed where the regions of crystallization of ice, carbamide, sodium dicarbamidochlorate, monoethanolamine dihydrate, monoethanolamine monohydrate, and anhydrous monoethanolamine were demarcated. The system is a simple eutonic.

Solubility in Systems Comprising Sodium Dicarbamidochlorate,Monoethanolamine Acetate,Ethanol, and Acetamiprid

The mutual effect of the components in four aqueous systems consisting of sodium dicarbamidochlorate, monoethanolamine acetate, ethanol, and acetamiprid are studied. No new compounds are formed in these systems. The components of the systems upon joint presence retain their individuality. The results for the systems under study demonstrate that a liquid defoliant exhibiting insecticide activity can be produced.     

Pulverized coal torch combustion in a furnace with plasma-coal system

Combustion of a pulverized coal torch has been numerically simulated on the basis of the equations of multicomponent turbulent two-phase flows. The results of three-dimensional simulation of conventional and plasma activated coal combustion in a furnace are presented. Computer code Cinar ICE was verified at coal combustion in the experimental furnace with thermal power of 3 MW that was equipped with plasma-fuel system. Operation of the furnace has been studied at the conventional combustion mode and with plasma activation of coal combustion. Influence of plasma activation of combustion on thermotechnical characteristics of the torch and decrease of carbon loss and nitrogen oxides concentration at the furnace outlet has been revealed.     

Plasma enhancement of combustion of solid fuels

Plasma fuel systems that increase the coal burning efficiency are discussed. The systems were tested for fuel oil-free startup of boilers and stabilization a pulverized-coal flame in power-generating boilers equipped with different types of burner and burning all types of power-generating coal. Plasma ignition, thermochemical treatment of an air-fuel mixture prior to combustion, and its burning in a power-generating boiler were numerically simulated. Environmental friendliness of the plasma technology was demonstrated.     

Study of the solubility of components in the NaClO3 · 2CO(NH2)2-NH2C2H4OH · CH3COOH-H2O system

The solubility of components in the NaClO₃ · 2CO(NH₂)₂-NH₂C₂H₄OH · CH₃COOH-H₂O system was studied by the visual polythermal method over wide temperature and concentration ranges. In the phase diagram, crystallization fields were determined for ice, urea, diurea sodium chlorate, acetic acid, monoethanolamine acetate, and the compound CO(NH₂)₂ · NH₂C₂H₄OH · CH₃COOH. The compound was identified by chemical, thermogravimetric, and X-ray powder diffraction analyses.
