Power Generation

Power generation is the process of converting stored chemical energy into mechanical energy, which is in turn converted into electrical energy to do work. In order to accomplish this, a fuel is combusted. Condensers and feedwater heaters are utilized to improve the efficiency of the cycle. Heat exchangers are often used to keep equipment cool and within material operating parameters.

• Feedwater Heaters
Feedwater Heaters gradually heat feedwater before entering a steam-generating boiler in a power plant. Depending on customer and plant requirements, feedwater heaters range in size and can be designed as horizontal, vertical head down or head up, and either high or low pressure units. All feedwater heaters are designed using AM-EX proprietary software and are built to ASME Section VIII Pressure Vessel Code requirements. When it comes to feedwater heaters, AM-EX will supply the largest of new, high-pressure supercritical units to small low pressure units.

• Condensers
Main steam condensers are a part of AM-EX’s product offering both as newly manufactured units or rebuilding and retubing old units. With proprietary condenser software, AM-EX can also design, fabricate, and install condenser modules.

• Air Pre-heaters
These extended surface units fit in the air duct feeding the boiler. Used to prevent cold and corrosion in a regenerative or recuperative primary air heater, air pre-heaters are often necessary for power generation systems.

• Shell & Tube & Miscellaneous Heat Exchangers
There are several types of heat exchangers that can be used in order to keep equipment cool and within material operating parameters. These units are simpler than feedwater heaters with no zones or internal shrouding. There is at least one tubesheet, and are covered by TEMA and API 660 standards. AM-EX specializes in the design, fabrication, and installation of new units as well as the service and rebuilding of existing units.
