How is the condensed water in the boiler formed?

With the upgrading of energy-saving technology of industrial boilers, condensing boilers with higher thermal efficiency are widely used. Some users will find that there is water flowing out of the tail of the boiler flue during use, they may consider the situation as the boiler is leaking, but it is actually condensed water in the boiler. This paper introduces how the condensed water in the boiler is formed and how ZOZEN Boiler uses the condensed water in the boiler.

How is the condensed water in the boiler formed?

Generally speaking, the principle of condensed water generation in boilers is that during the operation of boilers, steam is generated by industrial water and fuel energy, and the heat energy generated by steam is used to complete the industrial production process. When the heat in steam is released, its temperature drops and condenses, thus becoming condensed water.

The main components of condensed water in the boiler include: water generated by natural gas combustion, acidic substances generated by sulfur oxides dissolved in water from sulfur combustion in natural gas impurities, and acidic substances generated by nitrogen in the air and nitrogen oxides dissolved in water from oxygen in the air at high temperature.

If the condensed water in the boiler accumulates too much, it will affect the normal operation of the boiler, which will seriously cause water leakage at the joint between the rear smoke box door cover and the rear smoke box flange.

How to recycle the condensed water in the boiler?

As a boiler manufacturer integrating R&D and design, ZOZEN Boiler deeply studies the energy-saving technology of the boiler, understands how the condensed water in the boiler is formed, and formulates a reasonable solution. On the one hand, ZOZEN boiler recovers the energy in the hot flue gas (generally around 140℃) through the energy-saving device, and the temperature of the recovered flue gas is only around 60℃, so the thermal efficiency is improved by about 10%, which naturally saves about 10% of the gas. At the same time, in the process of energy recovery, it can also reduce the emission of harmful gases and reduce environmental pollution.

On the other hand, ZOZEN Boiler has designed a condensate recovery technology, which can recover the condensate water which is changed by steam releasing heat energy in steam equipment through a recovery device and send it to the boiler or other heat-using places for secondary utilization, which has a good energy-saving and water-saving effect. After in-depth research and test of this technology, ZOZEN Boiler successfully obtained the patent of steam boiler condensate recovery and utilization device (ZL20172001307.4), and successfully applied it in many projects.

The above is the principle of how the condensed water in the boiler is formed. If you need to buy a condensing boiler from us, please consult online.
