Background
The main function of the condenser is to create a low back pressure in the exhaust section of the turbine to maximize the work done by the steam, which is then cooled down to become condensed water and recovered. The function of the condenser is matched and ensured by a vacuum pumping system and a circulating cooling water system, the gas leaked into the condenser is continuously pumped out by the normal work of the vacuum pumping system, the normal work of the circulating cooling water system ensures that the steam entering the condenser can be timely condensed into condensed water, the volume is greatly reduced (under the condition of 0.0049Mpa, the volume ratio of the steam to the water in unit mass is about 2800), the water can be recovered, and the high vacuum of a steam exhaust part is also ensured. After the steam turbine completes an expansion process, the volume of exhausted steam is sharply reduced in a condensation process, and a space filled with the steam originally forms high vacuum.

1. in order to ensure that the interior of the condenser is always in a high vacuum state, an air extractor is required to continuously extract air leaking into the condenser and non-condensed gas contained in a steam clock, and the air and the non-condensed gas are generally directly extracted and discharged in the prior art, so that part of extracted steam is wasted.
2. Steam after the steam turbine uses has certain pressure, and prior art is in directly rushing into the condenser through the throat with steam, carries out the heat transfer with the water in the heat transfer pipe, but the steam of rushing into is not enough dispersed and speed is very fast for the area that contacts with the heat transfer pipe reduces greatly, has seriously influenced heat exchange efficiency.
