FLU-ACE Rice Process Boiler Exhaust Heat Recovery Systems

Thermal Energy International implemented the design and installation of two FLU-ACE Heat Recovery Systems at this manufacturing plant. The towers have run with minimal maintenance for 10+ years. There are two integrated condensing heat recovery systems.

The Rice Process Heat Recovery Tower

The 8.5 ft diameter FLU-ACE® tower was designed to recover 24 MMBtu/h (at peak) and 11 MMBtu/h (winter average) of otherwise wasted heat. Stainless steel breeching collects hot gases from three separate exhausts (two rice process dryers and one rice steamer). Recovered heat, in the form of 150ºF water, is sent to three plate heat exchangers which are used to heat:

  • Rice Process makeup water,
  • Rice and Cereal Process wash water,
  • Boiler makeup water, and
  • Fresh air makeup (through a secondary glycol heating circuit)

The FLU-ACE System, including controls, distribution pumps, and heat exchangers, are grouped inside specially designed enclosure for easy maintenance and accessibility.

The Boiler Exhaust Heat Recovery Tower

The FLU-ACE tower has an average heat recovery rate of 6.9 MMBtu/h. The system receives hot exhaust gases from two 70,000 lb/h boilers. Recovered heat, in the form of 150ºF water, is sent to three plate heat exchangers which are used to heat:

  • Boiler makeup water,
  • Fresh air makeup (through a secondary glycol heating circuit), and
  • Rice Process wash water.

The FLU-ACE systems helped the plant achieve significant savings, and consistently reduced plant energy costs and air emissions.

The Facility Maintenance Manager said:

As the Facility Maintenance Manager, my primary responsibility was Energy Conservation and Project Engineering. The FLU-ACE is a good, matter-of-fact, energy saver, and the best thing that we could have installed. It saved a bundle for [the company].
