With combustion experience since 1984, Nacah Tech has designed thermal oxidizers for many process applications. These successes have been generated by becoming quite familiar with the customer`s operation methods; # of streams to be treated, composition and concentration range from each stream, chlorinated (halogen) or acid presence, N-compound presence, air sources, quench water or air requirements, pre or post oxidizer motives, oxygen content, DRE requirement for organics, VOC`s and CO, etc. Nacah thus brings knowledge of past designs and new innovative designs to best suit the specified parameters. These parameters determine the best oxidizer design that includes the optimum: heat recovery versus capital cost, process gas introduction method and location, oxidizer operating temperature to meet the desired DRE, design and material selection of heat exchanger/boiler (if heat recovery is needed), the refractory selection that provides long life in designated service, and the ability to handle fluctuating inlet; flow rates, heat release from the streams, and their temperatures. Other device selections such as LEL monitors and flow meters, etc. are selected for optimum reaction time and method of measurement. This is done with our experience and the customer`s input for best operation.
We seek to be a member of your team to successfully furnish the optimum system.
Nacah specializes in economical custom designed thermal oxidizer systems. We have a wide experience in custom oxidizers. We use our experience to generate the best design using the optimum components for an economical system.
We offer free, up front assistance with emission flow rates and DRE`s that may help users interface with the regulators. Customers may also receive accurate budget pricing. I trust that our qualifications and abilities meet the high standards of today`s user. Nacah is pleased to review application(s), size and design the unit, and prepare a bid for a thermal oxidizer/combustion system, as needed. We`ll review the needs and offer design options to optimize the system. We then trust that the options convey their value added.
Although we normally have previous experience with similar application processes, we will work together to fully develop the best solution for each application. We are most glad to contribute in equipment supply or other capacities that you deem appropriate and needed.
Each Nacah thermal oxidizer system is designed to provide the following benefits:
Nacah appreciates the opportunity to assist you. We look forward to meeting with you when you have a need or wish to build a relationship. We want to work with you towards success on a future project(s).
We also provide associated oxidizer service, stacks, ductwork, combustion consulting, upgrades, bio fuel burning steam generators for small power production systems to join customer`s gasifier system, Selective Catalytic Reduction (SCR) of NOx, Waste Heat Boilers, etc. as needed. All are available quite competitively and economically. We provide designs and engineering while subcontracting the fabrication. Together, we will determine the best solution/approach, most economically.
Direct Fired Air Heaters
Direct fired air heaters provide hot gas to customer process. Economical combustion systems firing natural gas or other fuels most efficiently.
Combustion and Process Engineering Service
Nacah Tech has worked for Fortune 500 companies to small businesses to help them meet their emission and efficiency goals for their process/plant. Nacah is hired to help the client solve difficult problems. Not only issues concerning emissions are resolved, but simply to help your plant operate its combustion systems, kilns, rotary hearths, furnaces, oxidizers, most effectively to reduce downtime, scrap, fuel costs, and increase productivity of both the unit and the workers. Call Nacah Tech for engineering assistance with your combustion related equipment. We recently contributed as an advisory board member for a smoke/soot problem, completed an oxidizer retrofit of an oxygen analyzer to improve fuel efficiency, and visited several client plants to witness the operation in order to make expert improvement recommendations on the production process and the combustion system.
Fluid Bed Bead Activated Carbon VOC Concentration System
Recently, we have found great interest in our very high VOC concentrating system; a fluid bed concentrator that reduces the flow so much that the thermal oxidizer is very small. It concentrates significantly more than other competitive carbon methods. It is also economical where fixed beds or RTO`s are not. Nacah Tech integrates the ECTI fluid bed carbon system (and desorber) with the thermal oxidizer. It is normally more competitive than alternative methods of controlling high volumes with low concentrations and requires little/no replacement costs. Works great on large volumes
