Description

(54) SYSTEM OF PREPARATION OF AMPLEMENT WATER

one

The invention relates to a power system, namely to heat power plants.

Closest to the proposed is the system for the preparation of additional water, containing a contact water heater connected to the boiler flue through the heating coolant and equipped with branch pipes for drainage and supply of water, a turbine condenser, which has a Tenlo exchange surface connected to the consumer of additional water, as well as an evaporator 1.

Its disadvantage is low profitability due to heat losses of heated water, which is used for evaporating from the evaporator and reducing the efficiency of regenerative sampling.

The purpose of the invention is to increase efficiency.

The goal is achieved by the fact that the system is equipped with a water-cooled surface heat exchanger, the primary circuit of which is connected to the water outlet and supply nozzles of the contact water heater, and the secondary circuit is connected between the heat exchanging surface of the condenser and the consumer of added water.

The drawing shows a system for the preparation of additional water.

The system contains a contact water heater 1 connected to the duct 2 of the boiler 3 and equipped with nozzles 4 and 5 for drainage and supply of water, respectively, a turbine condenser 6, the heat exchange surface 7 of which is connected to the additional water consumer (not shown). The system is equipped with a water-cooled surface heat exchanger 8, the primary circuit of which is connected to the nozzles 4 and 5 of the outlet and the supply of water of the contact water heater 1, and the secondary is connected between the heat exchange surface 7 of the condenser 6 and the consumer of added water. The system is also equipped with a device 9 for chemical water purification, a deaerator 10, purge pipelines 11, and a feed bridge 12.

The system works as follows.

The escaping gases from the boiler 3 heat the water in the contact heater 1. The water from the contact heater 1 is heated. The pump is supplied to the heat exchanger 8 by the pump and, after cooling therein, enters the contact heater 1 again.

Claims (1)

Claim An additional water treatment system containing a contact water heater connected to the boiler flue through the heating coolant and equipped with branch pipes for water supply and discharge, as well as a turbine condenser whose heat exchange surface is connected to the additional water consumer, which is equipped with water-to-water surface heat exchanger, the primary circuit of which is connected to the water inlet and outlet nozzles of the contact water heater, and the secondary is connected between the heat exchanger overhnostyu condenser and make-up water by the consumer.
