Abstract:



Purpose.
Improving the conditions for dispersing harmful emissions from gas-consuming industrial furnaces based on the development of new complex methods for their greening using modern energy-saving technologies.


Methodology.
The known methods of heat exchangers and chimneys thermal calculation and methods for dispersing harmful emissions from thermal-energy plants in the environment were used.


Findings.
Calculative studies were carried out on improving the chimneys operation safety of glass furnaces of regenerative type when using technologies for waste heat recovery of furnace gases using water-heating and air-heating heat exchangers and chimneys of various designs. The influence of design features of chimneys on their operating modes when using heat recovery technologies with water and air heat recovery units has been studied. In order to improve the environmental efficiency and operational reliability of chimneys, it is proposed to use the thermal method of bypassing part of exhaust gases from regenerators past the heat recovery equipment in the heat recovery technologies. The effectiveness of this method for improving the dispersion in the ground-level of harmful emissions from furnaces when using the proposed heat recovery systems has been analyzed.


Originality.
For the first time, the application efficiency has been investigated of the proposed greening methods to improve the dispersion conditions of harmful emissions of gas-consuming glass furnaces in the environment under the conditions of using heat recovery technologies.


Practical value.
The results obtained will be used in the development of energy-efficient gas-consuming thermal installations for technological purposes.
