As the title suggests: Currently, in many factories, the condensate water generated as a result of steam heating is discharged under its own pressure at 4 kilograms and 120°C through specialized devices (or with the use of condensate tanks and pumps). In some cases, excessive leakage from steam traps can cause excessively high temperatures and pressures in the condensate pipeline network, preventing the condensate from being recycled and forcing it to be discharged on-site. 1. What are the options for making use of this condensate on-site? (As far as I know, the Xi Tai method is quite effective, with a comprehensive water consumption rate of 0.3.) How can this be implemented? 2. How can we prevent excessive levels of iron ions in the condensate from preventing it from being used directly as boiler feedwater? Manager Discussion Group
It is generally pressed directly into the condensate tank through pipes using back pressure. Heat exchange equipment is generally made of stainless steel, while steam pipes are made of carbon steel; it is difficult to keep iron ion levels within acceptable limits, so ion exchange must be carried out again.
I don’t know; waiting for an answer. . . . .
Schemes and practical applications for energy and water savings in steam pipelines and condensate systems
If it is about recovering condensate from pipeline heating, it is quite difficult; the condensate has to be collected in tanks at regular intervals, and pumps are then required in each of these tanks to transfer the liquid to a central tank. The economic viability has also not been actually calculated.
The system in operation features low-temperature water oil and iron removal technology; it utilizes the heat from condensate water, both for heating and for generating heat, to ensure comprehensive utilization of thermal energy. Currently, there are high-temperature oil and iron removal technologies that allow water to enter the system without the need for cooling; after treatment, the water is used for feeding the boiler.
If iron ions are not controlled and enter the deaerator directly, what problems will arise?
We collect the condensate uniformly and use it for the boilers...
It can be fed into the deaerator or hot water heating system; it can also be directed to a circulation tank to improve water quality
1. Start from the source, that is, use quality-approved check valves to reduce air leakage. The greater the amount of steam that leaks, the more cooling water is required for recovery, which is far too costly. 2. A closed condensate recovery system is employed to reduce the amount of oxygen entering the condensate, thereby preventing pipe corrosion and excessive levels of iron ions. Today, condensate relay pumps (powered by steam) are well-developed and capable of recovering dispersed condensate.
