Automated and Continuous Steam Trap Monitoring Solution

What is a Steam Trap? A Detailed Overview of Steam Traps in Steam Systems

A Steam Trap là một thiết bị quan trọng trong các hệ thống hơi nước, được sử dụng để loại bỏ nước ngưng tụ (condensate) ra khỏi đường ống mà không làm thất thoát hơi nước. Vai trò chính của bẫy hơi là đảm bảo hệ thống vận hành hiệu quả, tiết kiệm năng lượng và ngăn ngừa các  sự cố của hệ thống phân phối hơi do nước ngưng tích tụ.

How Steam Traps Operate

Steam traps function by distinguishing between steam and condensate. As steam passes through the system, a portion condenses into water due to heat loss. The steam trap automatically opens to discharge the condensate and closes to retain the steam. There are three common types of steam traps:

1. Mechanical Steam Traps:Operate based on the density difference between steam and condensate (e.g., float traps or inverted bucket traps).
2. Thermodynamic Steam Traps:Utilize pressure and temperature differences to open or close the valve.
3. Thermostatic Steam Traps:Function based on the temperature difference between steam and condensate.

Challenges in Monitoring Steam Traps in Steam Systems

Monitoring steam traps is a critical task to ensure the efficiency of steam distribution systems, yet it faces significant challenges. Below are the primary issues associated with steam trap monitoring.

Research indicates that approximately 30% of steam traps in industrial systems fail annually. Failures in steam traps lead to issues such as steam loss, reduced system efficiency, and increased operational costs.

Costly Traditional Inspection Methods

Traditional steam trap inspection methods, such as using temperature or ultrasonic measurement devices, are often complex and time-consumingThese processes require skilled personnel, specialized equipment, and, in some cases, system shutdowns, which disrupt production.

Inefficient Periodic Inspection Cycles

Steam traps are typically inspected at intervals of 3, 6, or 12 monthsresulting in delayed detection of failures. During the periods between inspections, malfunctioning steam traps may go unnoticed, leading to unaddressed energy losses.

Consequences: Significant Energy Losses

Due to these challenges, 5-10% of the total energy costs in steam systems are lost as a result of leaking or malfunctioning steam traps.

Blow Through Trap and Cold Trap in Steam Trap Systems

Blow Through Trap occurs when a steam trap fails in a continuously open state, allowing steam to escape along with condensate. This condition is commonly referred to as "blow-through" because steam passes through the trap without being retained.

Consequences of Blow Through Trap:

• Increased costs for steam procurement.
• Risk of insufficient steam supply for downstream processes.

Cold Trap occurs when a steam trap fails in a continuously closed state, preventing condensate from being discharged. As a result, condensate accumulates in the trap and flows back into the steam distribution system.

Consequences of Cold Trap:

• Water Hammer: Nếu nước ngưng đi vào đường ống  phân phối hơi, dưới áp lực cao có thể gây ra hiện tượng búa nước, tạo ra các va đập với áp lực rất lớn tại các vị trí như co, tee dẫn đến hư hỏng đường ống, phụ kiện => Mất an toàn lao động.
• Reduced System Efficiency: Escaping steam lowers pressure and temperature, leading to inefficient steam utilization and necessitating extended heating times.
