Application of vacuum units in power plants and the value created

Energy efficient Roots water ring vacuum unit

This technology is applied to the condenser vacuum pumping system of a Power Plant. Compared with the original vacuum pump, the energy saving rate reaches 80%. At the same time, in the summer when the working water temperature is high, the vacuum of the condenser can be effectively improved (under the same conditions and conventional Water ring vacuum pump compared).

This technical feature

1) The original design of vacuum equipment is mainly used as a rapid vacuum establishment in the initial stage of turbine startup. It requires that the unit start-up requirements be achieved within 30 minutes. In normal operation, there is no need for such a large demand. Therefore, in the normal operation, the purpose of energy conservation is achieved by means of small generations.

2) The efficiency of the conventional water ring pump (or water jet pump) is low (30%). The efficiency of the high-performance vacuum pump used in this technology is as high as 70%. Therefore, the use of an efficient Roots water ring vacuum unit can achieve energy savings.

3) The pumped gas includes non-condensable gas (air) and condensable gas (water vapor), and most of the gas is water vapor. By condensing the water vapor, the total load of the water ring pump compressed gas can be reduced to achieve high efficiency. The goal of energy conservation.
