Kompleksowe wdrożenie energooszczędnych napędów oraz automatyzacji produkcji i dystrybucji ciepła w Ciepłowni Rydułtowy

This paper presents the project "A combined energy efficient motors and control system for heat production and distribution in the Cieplownia Rydultowy boiler house", which has been carrying out in Cieplownia Rydułtowy Ltd in cooperation with the Polish Foundation for Energy Efficiency (FEWE). The purpose of this undertaking is improvement of reduction of production costs of the company with minimum effect on environment. Among other things a frequency converter for a motor (160 kW) of a main circulation pump has been assembled. Frequency converters have also been assembled for exhaust and air fans in a boiler (motors with 170 kW total power). Moreover, weather compensation and automatic gain control has been assembled in 23 heat exchangers. Currently other undertakings are carried out thanks to the FEWE financial aid, e.g.: assembling frequency converters for motors in the other boiler, control system for coal combustion in the boiler, replacement of old pumps for pumps with energy efficient motors in heat exchangers and assembling a telemetry system control in a few heat exchangers. These undertakings will bring a notable effects in the form of decrease in electricity and fuel consumption as well as decrease in emission of gases and dusts.
