Working principle of surface condenser
Article source: unknown Publisher: admin
The working principle of surface condenser:
The condenser is equipped with a large number of copper pipes and is circulated with cooling water. When the exhaust steam of the steam turbine is in contact with the outer surface of the copper tube of the condenser, the latent heat of vaporization becomes condensate due to the cooling of the water flow in the copper tube. take away. In this way, the exhaust steam is continuously condensed through the condenser. When the exhaust steam is cooled, its specific volume decreases sharply, so a high vacuum is created inside the condenser under the steam turbine exhaust port.
Condensers are large heat exchange equipment for thermal power plants. When the condenser is running, the cooling water comes in from the lower half of the front water chamber, enters the rear water chamber through the cooling water pipe (heat exchange pipe), folds upward, and then flows through the upper half of the cooling water pipe to the forward water chamber and is finally discharged. The low-temperature steam comes in from the steam inlet, flows down through the gap between the cooling water pipes, and condenses into water after releasing heat to the pipe wall. Structure Description The structure of the condenser is single shell, bisect, single flow, surface type. The condenser is a single-shell split-single-flow surface-type condenser, which is arranged laterally under the low-pressure cylinder. The condenser housing is placed on a spring support, and the upper part of the condenser housing is rigidly connected with the steam engine exhaust cylinder. The circulating water flows through the condenser tube bundle to condense the exhaust steam of the turbine in the condenser shell, and the condensed water is collected in the hot well and discharged by the condensate pump.
A tube bundle is arranged in the condenser shell, and the hot well is placed below the shell. At normal water level, its water volume ensures that the condensate pump runs for a certain period of time.
The condenser consists of a shell and a tube bundle in a single flow. The tube is a copper alloy tube, which is cooled with fresh water. The throat of the condenser is connected to the exhaust pipe of the low-pressure cylinder of the steam turbine. The lower part of the neck is a truncated cone. The left and right sides are symmetrically arranged, and two desuperheaters are installed. Condenser hot well: A water collecting well that collects condensed water in the lower part of the condenser is placed under the steam engine room. The function is to collect condensate water and provide a certain static pressure head for the condensate pump.
