Market Areas:Heat Recovery Systems
As industrial representatives for Des Champs, D.F. Brandt can provide payback analyses for application of air-to-air heat recovery systems on virtually any process that creates waste heat. Process ovens, furnaces and thermal oxidizers are but a few of the systems that can be optimized by recovering waste heat to increase the efficiency of the process, in the form of combustion air preheat, for instance, or utilization in space heating.
Schematic of a counterflow heat exchanger. DesChamps exchangers are available in a wide range of materials for operating temperatures exceeding 1500F with thermal efficiencies up to 85%. Special construction and plate spacing available for particulate laden airstreams.
This process heat exchanger utilizes ambient outdoor air to indirectly cool process exhaust from 900F to 250F prior to entry to a fabric baghouse. This heat exchanger resulted in the reduction of actual process air volume at the reduced air temperature and allowed use of a smaller dust collector than that which would have been required had outdoor air been mixed with the process air to reduce temperature.
