Experience of Technical Re-Equipment of the Outdated Boiler Equipment of the Southern Mining and Concentration Plant for Increasing its Industrial Output and Improvement of Technical, Economic and Environmental Characteristics

Abstract

The principle of technical re-equipment of morally outdated equipment with an increase in the industrial capacity of boilers for the needs of the production of the Semi-Owned Gas Power Plant due to the implementation of modern technical solutions while maintaining the overall dimensions of the boiler room, which already exist, is presented. The boiler house is designed to cover heat loads of consumers. Technical re-equipment is aimed at improving the energy performance and environmental characteristics of the boiler house equipment as a result of the implementation of modern technical solutions with highly efficient equipment in the boiler house. The equipment used for the implementation of technical re-equipment of a real industrial water-heating boiler house is analyzed. It is noted that the use of water heating boilers of Viessmann Vitoplex 200 type Sx2A with economizers VITOTRANS 300 in accordance with the requirements is the most expedient, indicating the needs of the enterprise and the advantages of the equipment. It has been established that the re-equipped boiler house has significant advantages compared to the previously operating one, the result of the modernization of the boiler house of the South GZK is not only the technological ideas laid down in the project, but also the material result in the form of a new energy facility put into operation. The development of the project assumes that the main type of fuel is natural gas with a lower heat combustion heat Q = 8100 Kcal/nm³, reserve fuel for this boiler house is not expected. Taking into account the technical conditions of the potable water supply of the boiler house and the need to fill the heating networks with treated water, the Na-cation water installation "BWT" was used in the boiler house. New technical equipment was installed: five Viessmann Vitoplex 200 type Sx2A water heating boilers with a capacity of 1100 kW each, five gas burners, five Vitotrans 300 economizers, five boiler circuit pumps, five economizer bypass pumps, air separator, sludge separator, two mains pumps, BWT water softener, two feeding pumps, two 1250l prepared water storage tanks (eurocube), manufactured by "SCHUTZ" company; distribution collectors (supply and return) with a diameter of 325 mm and a length of 2 m each; two expansion tanks Reflex G3000 6 bar/120 °С, volume 3000 l each, five expansion tanks of the boiler circuit Reflex G300 6 bar/120 °С, volume 300 l each, manufactured by the company "Reflex" (Germany); dosing station DOZOMAT 60АТ.МТ2, which made it possible to reserve 38 % of the boiler house capacity.
