  • Increased operating profit by reducing financial penalties
  • Reduction of insurance costs
  • Avoiding unscheduled outages
  • Increased availability and tube life
  • Reduction of secondary damage
  • Increased personal safety

Why is early detection essential?

For Utilities -To prevent expensive secondary damage and unscheduled outages in boilers, feedwater heaters, headers, steam pipes and valves.

For Paper Mills -To prevent smelt water explosive reactions in recovery boilers.

For Process Plant -To provide early warning of leaks in steam pipes, valves and heat exchanges.

The real costs of undetected tube leaks

EPRI Report No RP1863 showed that electrical power generation plants have, on average, around 6% loss of plant availability due to boiler tube leaks.

The survey over USA & Europe found that boiler tube leaks were the single biggest cause of lost availability.

Detecting leaks by measuring make-up water or walking the boiler is very insensitive and usually gives information about the existence of a leak only when that leak is already large & creating serious secondary damage.

The Leak Detection System | Steam Leak | Lintvalve is designed to detect a steam leak the moment it begins, allowing time for a planned schedule to shut down the boiler at an optimum time, such as the weekend. Thus resulting in substantial reduction of repair times and costs with a consequent increase in availability and profits. The early detection of a tube leak will give financial savings which will easily exceed the initial capital cost of the detection system even at the first steam leak event.

Lintvalve has over 25 years experience in detecting leaks.

The first commercial leak detection system in the world was installed on a boiler in 1974. With more than 250 installations in over 20 countries world-wide Lintvalve can proudly claim more experience and success than any other company in the field.

Typical System Overview of Leak Detection System | Steam Leak | Lintvalve

The Leak Detection System | Steam Leak | Lintvalve consists of:

Patented Airborne Sensors: Lintvalve's acoustic microphone is shock and vibration resistant and 30 to 50 times more sensitive than piezo-electric microphones. This sensitivity enables the system to locate even very small leaks and gives you the time you need to plan a proper course of action for repair.

Plate Microphone: Piezo-electric based sensors, which use the boiler wall as a diaphragm to convert airborne audio signals into acoustic signals. The Lintvalve system uses plate microphones in areas where ash or salt cake build-up prevents the use of microphones which require an open pathway.

Structure-Borne Sensors: Piezo-electric based sensors measure ultrasonic sound generated by leaks in the boiler structure. Especially effective in lower furnace water wall area where hot slag readily blocks open pathways to a microphone or shatter sprays produce high levels of audio noise.
