Overview of low-pressure heater (low-pressure heater):

The function of a low-pressure heater, abbreviated as a low-pressure heater, is to use the steam that has done some work in the turbine to extract it into the heater to heat the feedwater, increase the temperature of the water, reduce the amount of steam discharged from the turbine to the condenser, reduce energy loss, and improve the circulation rate of the thermal system. The conclusion is that a vertical tube plate heater is commonly used. The heating surface of the heater is generally composed of straight or U-shaped tube bundles made of brass pipes or slotted steel pipes.

Low pressure heater (low pressure heater) - output potential:

Low pressure heater, low-pressure heater. The heated water enters the separated water chamber from the upper inlet pipe and then flows into the U-shaped pipe bundle. The U-shaped pipe absorbs the heat of the heated steam in the steam space of the heater, and is transferred to the flowing water inside the pipe by the pipe wall. The heated water flows out through the outlet water chamber of the heater.

Working principle of low-pressure heater (low-pressure heater):

The low-pressure heater (working principle of low-pressure heater) has both self flow and drainage pump circulation, and the difference in equipment is whether there is a drainage pump- A general power plant uses condensate water directly from the shaft seal heater to the low-pressure heater (different systems have different numbers, for example, 125MW and 300MW have 4-)

Low pressure heater, low pressure heater malfunction and measures:

1. The pipe bundle at the steam inlet is easily damaged by steam flow erosion. Low pressure heaters usually install a door protection baffle on the steam inlet pipe bundle to disperse steam flow and reduce its impact. 2. The heated water vaporizes in the heating water pipe of the heater, causing a water hammer. To prevent this phenomenon, it is required that the pressure of the heated water should be higher than the pressure of the heated vapor. 3. Non condensable gas accumulation. The air discharge pipe installed on the heater should be kept unobstructed.

Low pressure heater, low pressure heater structure - form:

Lianyungang Lingdong provides high and low pressure heaters (low-pressure heaters), which are vertical devices. The internal heating pipes are divided into two categories: disc-shaped pipes and U-shaped pipes, each with its own length, and can be selected according to user needs!

Low pressure heater, low pressure heater supply range:

1. Standardized production - and supporting production for the host factory-

2. Design and customize doors according to user requirements

3. Undertake maintenance such as replacing tube bundles and other equipment renovations, as well as technical renovation services

4. Provide high-pressure accessories such as heat exchangers and sealing rings
