In the summer of 2012, JSC St. PetersburgHeatingGrid will start a target program of modernization of water treatment facilities of the heating system in the Krasnoselsky district. Modern inertia and gravitation mud filters will be installed at six central heating points of the Company.
Filters at the entry of the heating agent into the heat point will provide for optimal water clearance from mechanical impurities of 16 micron or greater (such as pipeline corrosion products, sand or clinker) and thus a significant raise the quality of hot water supply to households.
Mud filters not only allow efficient filtration of hot water that is supplied to buildings but also protect heat point machinery from negative impact. This will enable JSC St. PetersburgHeatingGrid to optimize heat network maintenance costs. The normative life limit for these machines is 10 years or more.
The new water treatment systems will be installed at heat supply facilities without any restrictions in hot water supply to consumers.
It should be reminded that last year, such
systems were installed at six central and two main heat points of St.
PetersburgHeatingGrid in the Kirovsky district.
Reference:
A central heat point is a facility for
connection of heat supply systems of a microdistrict to distribution heat
networks and for management of heat consumption systems of buildings. It is
used to serve a number of houses and is usually located in a standalone
building.
The heat network system of JSC St. PetersburgHeatingGrid has a total of 91 heat points with 1,150 Gcal/hour coupled load. They were posted on the Company's balance sheet last year and previously they had been owned by the city.
This year, the company will perform various jobs for reconstruction of 39 of its heat points in the Frunzensky, Kirovsky, Krasnoselsky, Kalininsky, and Nevsky districts.
