Shostka Thermal Power Station (TPS)

When speaking about Big Energy, we, in the first place, have in view the generating enterprises, namely, TPS and CHP plants, the majority of which have been constructed about five to six decades ago. The many years' service has confirmed the characteristics of high-performance equipment. But there is nothing permanent: the equipment deteriorates and becomes obsolete and even constant repairs are unable to provide its design values. Therefore, sooner or later, the question of replacement of existing equipment by the new one arises. When selecting the new equipment, the other changes that took place over the last half century, namely, the new fuel types, water quality changes, new loads and energy consumers, technological innovations and different approach of new owners to management practice are to be taken into account. The latter is especially true in regard to CPH plants as the majority of them have already been bought or let on lease. 

In due time, Shostka TPS was constructed as a source of energy, heat and steam with due account of the outside steam consumers, for example, such as SVEMA Production Association (PA). In addition to the industrial enterprises, the plant provided and still provides the majority of town citizens with heat and hot water. The design chemical water treatment capacitance at TPS amounts to 400 m3/h. It was designed with the account for steam supply to SVEMA PA.

In the second half of the year 2000, the Government made a decision to withdraw TPP from SVEMA PA and transfer it into the municipal ownership. At present, all outside consumers have terminated their activities and the demand for demineralised water has reduced. A number of technical problems related to operation of filters, pumps and big-diameter pipelines at light loads appeared. This resulted in high expenditures on the in-house needs and high cost of 1m3 of chemically treated water. In connection with this, the plant authorities came to a decision to install a new complex of water treatment equipment that complies with the today's requirements and operates in the fully automated mode with the minimum operating costs.
The technicians of Jurby WaterTech International prepared the technical and commercial proposal based on the advanced technologies AquaHard and JurbyFlow which was found to be the optimal proposal for the TPS providing the low cost of 1 m3/h of treated water. The design time of return on investment for equipment is 2 years. 
The water treatment complex is intended for the replacement of water losses of БКЗ 160-100 and БКЗ 120-100 steam drums cycle, as well as, for the make-up of heat network.
The water treatment system of 80 m3/h total capacity is composed of filtration plant, softening plant and demineralization plant.
The water demineralization is performed in the two-stage reverse osmosis plant. The scheme of the reverse osmosis concentrate use for the make-up of heat network proposed by Jurby WaterTech International is one of know-how. And above all, it will enable to decrease the amount of drained water that in addition to its environment conservation component effects a substantial saving on the enterprise costs.
The automatic control system makes it possible to carry out the archiving of operating parameters that provides the service engineers with the possibility to efficiently determine the causes of faulty operation and eliminate them in due time.
Presently, Jurby WaterTech International has made a delivery of equipment to the Customer's warehouse. After preparation of the shop premises, the chemical water treatment equipment will be transferred for installation together with the performance of commissioning works.
We will keep you informed about the progress of works on this project and also provide you with more details on the remarkable for Ukraine changes at Shostka TPS taking place because of a very natural wish of each owner to work more efficiently.
