International Cleaner Production Center together with the “First
Energy-service company” have started introduction of latest energy
effective technologies within the framework of implementation of
the demonstration cleaner production project. The complex of the
Business-center buildings at Konnogvardeisky boulevard in St-Petersburg
was chosen as a pilot object. In basis of modernization of the heat
supply system of office buildings was putted a unique domestic heat
generating installation. The installation belongs to category non-traditional
ways of energy generation and uses a water interior energy resource.
Now such technology has no domestic or foreign analogues by technical
and economical characteristics.
As the first
stage of project implementation the previous hot water system based
on three electric boilers with total power 9 kW was replaced by
new one, based on heat-generator which uses the resource of internal
water energy (with electrical power consumption – 6 kW).
characteristics of new and the previous hot water systems show that:
daily temperature of hot water on boilers outlet is 31-32 C;
but at the same time the temperature is not stable and changes
during twenty-four hours (see picture No1);
daily temperature of hot water on water heat-generator outlet
is 60 C and keep stable (see picture No2);
heat-generator is easy build in(see picture photo) into supply
pipeline system; but boilers need separated space(room).
the using of water heat-generator cost per unit of electric power
for unit of the producing heat power are in 2.7 times less, than
at the previous engineering solution (boilers scheme). It shows,
with electrical power consumption of 6 kW heat-generator produces
on outlet heat power from 15 to 18 kW.
And all sanitary-technical standards are maintained (hot water temperature
in the system is not less then 55-60 C), which has not been fulfilled
because of insufficient power of boilers.
The main advantage of the given technology is minimum pay-back periods
of such projects.
So, in the described above project, an expected seasons financial
expenses on provision the complex of buildings by the hot water
supply after its modernization will reduced twice.
mean daily temperature characteristics:
Energy-saving projects (from public and industrial energy till local
heating systems of private sector, different kinds of pools, etc.)
which are realized on the base of this technology, permit to reduce
consumption of any kinds of organic fuel (diesel oil, black oil
fuel, gas, coal , etc.) more, to increase the outlet power of nowadays
heat-generators, to reduce heat losses, to save financial resource.
any futher information or implementation possibilities, we are always
at your disposal.
