Nacah Tech LLC news
Nacah Tech LLC direct fired thermal oxidizers (DFTO) or other custom thermal oxidizer systems keep plants running most efficiently with high online rate. Rich or varying combustibles, N compound laden, low O2, or dirty streams require custom engineering to provide the optimum design. Nacah Tech DFTOs handle difficult gas streams. The DFTOs may include specially designed heat recovery to improve the plant`s operating efficiency, scrubbers, and / or stacks, often with plot space saving designs.
Process Heating Magazine chose to feature a Nacah Tech LLC thermal oxidizer for their February 2013 cover photo. The photo shows a thermal oxidizer with incoming waste gas vertical inlet, end fired natural gas burner with auxiliary natural gas fuel train, preheat combution air duct, therminol heater, and stack. Contact Nacah Tech to discuss your application and determine its optimum solution. rkeibler@nacathech.com</
Reduce Your Plant’s Operating Fuel Costs by watching your P’s & Q’s:
A plant tracked the products of combustion and the oxygen quotient (percent oxygen) in those POC’s to determine that lowering the oxygen (excess air rate) would result in reduced operating costs. Nacah Tech LLC completed a project to improve the fuel efficiency of the existing thermal oxidizer. The work involved the supply, integration, and installation of an oxygen trim s
Nacah Tech LLC’s President, Bob Keibler, was recently interviewed by Pollution Engineering magazine and the resulting audio was distributed by the publisher as a podcast. A transcript of the interview is available on both the Environmental Expert site under Nacah Tech or at www.nacahtech.com/articles.html. Bob describes how new U.S. federal regulations may impact a plant’s existing equipment and, if it is best for the ther
NacahTech provides custom-designed solutions for difficult air pollutants
Nacah Tech systems concentrate compounds from large “air” streams at a rate up to 500:1 and then combusts them at 99%+. The compounds are then destroyed in an extremely small thermal oxidizer with very little, if any auxiliary fuel or power needed. To solve the problems, complete systems are designed to include: collection fan, carbon adsorber, desorber, (concentrator) thermal
Direct fired units (DFTO) are custom designed to accommodate unique appliation considerations. DFTOs may include either an externally mounted nozzle mix burner (shown) or an inline duct burner.
