A non-return type steam trap is specifically designed to allow condensate to flow out while preventing steam from returning to the system. This type of steam trap discharges directly into a component that can handle the discharged condensate, typically a receiver or heater.

The reasoning behind this is that the receiver or heater is crucial for collecting the condensate, which can then be returned to the boiler for reuse or could be drained or disposed of in a safe manner. A non-return type steam trap operates ensuring efficient drainage of the condensate and preventing steam loss, thereby optimizing energy usage and system efficiency.

In contrast, discharging to a boiler or pressure vessel would not be appropriate, as those components are not designed to handle condensate directly; they are meant for steam or pressurized fluid. Similarly, discharging directly to a steam line would defeat the purpose of the trap, as it would allow steam to escape, which is what the trap is designed to prevent.
