Steam traps are an essential component of steam heating systems to eliminate condensate and non-condensable gas that form in industrial facilities and processing plants’ steam lines. Steam traps are used for tracer lines, tank heating coils, steam-heated equipment, and power-drive equipment to discharge condensate while eliminating live steam losses.
It is necessary to use steam traps in steam lines to avoid unwanted condensate from entering a system, the traps allow steam to reach its destination remaining as dry and clean as possible. Condensate entering the steam system can result in inefficient operation, reducing the heat transfer area and heater performance which can be economically damaging due to corrosion, water hammer and accumulated dirt.
Conventional steam traps cause expensive live steam losses, ranging from 2 lbs/hour to well over 5 lbs/hour, gradually increasing over time. They can also cause temperature variations on piping, which may affect the processes they supply. ThermOmegaTech’s thermostatic steam traps completely eliminate these costly issues.
Thermostatic steam trap valves operate by the change in fluid temperatures and prevent live steam loss by draining only condensate that has fallen well below the saturated steam temperature to the valve’s set-point temperature. When there is a loss of heat in the steam space, the condensate temperature will decrease and the thermostatic trap will allow condensate through when it senses a low temperature however, as the steam reaches the trap, the temperature will increase signaling the trap to close. This reduces total steam usage, improves heating efficiency, and saves a significant amount of money.
ThermOmegaTech’s HAT valves sense condensate temperature and open to allow flow only when the condensate temperature is below the setpoint, well below saturated steam temperature. The condensate forms a liquid seal ahead of each valve preventing live steam losses. Also, the sensible heat in the condensate between steam temperature and the HAT discharge temperature is used for heating.
HAT (Heat Actuated Trap) or TV/HAT (Tube Valve Heat Actuated Trap) valves used on tank heating coils limit the temperatures of the heating element. By closing before coil temperatures are too high, the HAT or TV/HAT valves reduce the risk of over-temperature damage.
When used as a sub cooling steam trap, HAT or TV/HAT valve reduce problems associated with overheating and unwanted condensate. These self-actuating, thermostatic steam trap valve modulate open and closed to maintain a constant temperature discharge in commercial or industrial heating systems.
