Elektrociepłownia Lublin Wrotków - Opis:
- The article contains general information about the modernization of the PWS6 pump drive with respect the whole modernization process of the circulating water pumping station at the Lublin-Wrotków CHP Plant. The circulating water pumping station is the biggest system at the plant, with the total installed power demand of 5,8 MW. It includes seven pumps (three pumps type 35W50 and four modernized pumps type 35W50M). The pumps operate in parallel and supply a common collector for the demand of the Lublin District Heating System. Two pumps are controlled by regulation of rotary speed one by means of frequency converter and the next one through a sub-synchronic cascade system. At present, the system is overloaded (in terms of hydraulic) with one or two controlled pumps, or three pumps while one pump has no control. In order to keep the system supply parameters the non-controlled pump must be throttled. Modernized PWS6 pump (new motor and frequency converter) lets replace a non-controlled pump (in case of three pumps operation) or the pump controlled through a cascade system (in case of two pumps operation). As a result, the system will operate without throttling losses. It is estimated that the achieved savings in electricity consumption will reach about 900 MWh per year. It implicates significant financial savings just as environmental effect (reduction of emissions).
