Air Heaters & Recuperators

John Zink's air heaters and recuperators are advanced combustion solutions designed for indirect-fired process gas heating applications, ensuring clean air contact with products and high efficiency in heat transfer.

John Zink's air heaters and recuperators are engineered for optimal performance in drying processes and other applications requiring process temperatures above 200°C. These units are suitable for a range of industries, including chemical processing, hydrocarbon processing, and power utilities. The air heaters are capable of achieving maximum process air outlet temperatures of 500°C for compact units and up to 1,000°C for direct-fired heater units. They are designed with a stainless steel combustion chamber and an integrated convection tube bundle, which allows for short start-up times and high turn-down ratios.

Features

  • Indirect and direct-fired process gas heaters suitable for a variety of applications
  • Compact heater units ranging from 50 kW to 6 MW, with larger capacities available for specific needs
  • Stainless steel construction with limited use of refractory material for durability and quick start-up
  • High turn-down ratios and flame temperatures of approximately 1,400°C for efficient combustion.
  • Integrated convection tube bundle for effective heat transfer
  • Fuel flexibility, with options including natural gas (NG), liquefied petroleum gas (LPG), light fuel oil (LFO), and heavy fuel oil (HFO).

Benefits

  • High efficiency with potential to exceed 90%, depending on the fuel used.
  • Clean air process ensures that products are not contaminated by flue gases, maintaining their quality and integrity
  • Short start-up times enhance operational flexibility and reduce waiting periods
  • High turn-down ratios allow for precise control of heating, improving process stability
  • Robust construction and design considerations lead to a long service life and reduced maintenance costs.
  • Customizable solutions to meet specific process requirements and industry standards.
