What is the function of condensate trap in gas flue of the boiler?

To meet the demand of clean heat, gas-fired boiler has become the necessary heating equipment for most enterprises. However, users still don't know much about the gas boiler system, and they often encounter the selection of auxiliary equipment such as condensate traps in the flue of gas boilers when purchasing boilers. Here, ZOZEN Boiler introduces the working principle of condensate traps in gas boiler flue.

Condensate water trap of boiler flue

Condensate water trap in gas flue of boiler is to continuously discharge the condensate water in flue to the outside of pipeline.

The function of the condensate trap in the gas flue of the boiler is to quickly remove the produced condensate, prevent steam leakage, remove air and other non-condensable gases, ensure the normal working condition of each boiler and reduce the loss of working medium in the thermal system.

The principle of condensate trap in boiler flue is to drain and block steam, which is an automatic valve. When steam becomes condensate, the temperature will also decrease, and the heated elements in the trap will contract. In this process, with the flow of condensate, the steam will inevitably be taken out, but the steam will heat the heated elements in the trap to expand and close the valve. The position of this heating element can be adjusted. When the exhaust volume of the steam trap is too large, the position can be pressed, otherwise, the position can be loosened. The basic function of steam trap is to discharge the condensed water, air and carbon dioxide gas in the steam system as soon as possible; At the same time, the leakage of steam can be prevented automatically to the maximum extent.

ZOZEN has SZS series and WNS series condensing gas boilers, with a capacity of 1-110t/h and 0.7-116MW, meeting the needs of most users.
