Heat Exchanger Tubes

Power boilers consist of a large combustion chamber used to generate heat.  Heated air is passed across a series of heat exchanger tubes that create steam.  The steam is used to turn the turbines that generate the electricity.  The faster the steam is generated, then the faster the turbines can turn, and the greater the electricity that can be produced.  For any given plant geometry, the amount of steam that can be produced is proportional to the amount of heat generated in the combustion chamber and the rate of heat transfer through the heat exchanger tubes.

 

Improved process efficiency

Reduced maintenance

Protects against catastrophic damage.

Temperatures within the combustion chamber are limited by the high temperature thresholds of the refractory brick and the heat exchanger tubes.  If the temperature of either of these two components becomes too hot, then catastrophic damage will result.  When overheated, refractory materials will vitrify (glass over), and lose much of their insulating properties.  Similarly, heat exchanger tubes will soften and crack when heated beyond their design limits.

 

Heat is extracted from the combustion chamber through the heat exchanger tubes.  As they become soiled their efficiency is reduced dramatically.  As their heat transfer efficiency drops the surface temperature increases, and the steam generation is reduced.  For coal-burning plants, fly ash becomes much stickier at higher temperatures; therefore, heat exchanger efficiency is greatly enhanced by controlling the fly ash temperature.

 

The model is used to measure refractory wall and heat exchanger tube temperature to assure efficient operation and to identify when the tubes need to be cleaned.  This sensor operates over a broad temperature span, and is designed to view through products of combustion without interference.  The Williamson dual-wavelength model DW-08, which tends to measure only the hottest temperature viewed, is used to monitor fly ash temperature near the bottom of the heat exchanger tubes, and also to measure flame temperatures within the firebox.

 

We offer a broad range of alloys, sizes, and specifications.  Whether your application requires seamless or welded stainless steel tubing, you can always count on consistent, high quality tubing manufactured by our specialists at Plymouth Tube Company.

Customers turn to TS for some of the world’s longest lengths of carbon and stainless tubing. Teaming with an agile manufacturing partner able to tailor products to your unique requirements (including value-added finning, bending and other finishing services) provides you with a single source of tube solutions. That helps minimize the potential risk factors faced when working with a less manageable supply chain.

 

When you need tubing and you need it now, TS's 24/7 emergency service gets your heat exchanger equipment up and running again or, better yet, helps you avoid unplanned shutdowns in the first place. TS employees know that when refinery and chemical plant equipment is down, every minute counts.


Boiler tubes and heat exchanger tubes

A high temperature and pressure resistance, depending on the application – an increased or reduced heat transmission as well as good processing properties in regard to bending techniques are essential properties of boiler tubes and heat exchanger tubes. 

Thanks to our close business ties to leading steel tube manufacturers, we can, in addition to the standard grades EN, ASTM, ASME and AD, also supply special dimensions and grades such as Duplex, Super Duplex or Hastelloy, Incoloy and titanium alloys on short notice. Furthermore, we offer the complete range of processing techniques relevant in today’s market.
