Direct-fired Process Heaters

Struthers Wells has sold over 2,500 direct-fired process heaters, the majority being of the cylindrical radiant-convective design. They have also sold hundreds of others of various special arrangements, such as radiant wall-fired cabin heaters, floor-fired cabin heaters with multiple zones, top-fired reformers, and many other configurations to suit the specific application.

Here is a sampling of our broad range of experience:

• Ethylene dichloride (EDC) cracking furnaces of radiant-wall design
• Acetic acid pyrolysis (ketene) furnaces of radiant-wall design
• Ethylbenzene/steam superheating furnaces for styrene monomer plants
• Propane cracking furnaces of the floor-fired cabin type
• Titanium tetrachloride (TiCI4) vaporizers and superheaters
• Oxygen heaters
• Unique oxygen-natural gas combination preheater furnaces for acetylene plants
• Triple-compartment, cabin-type naphtha reforming furnaces
• Radiant-wall and top-fired steam-methane
• Fluorocarbon cracking furnace of top-fired cabin design
• Once-Through Steam Generators (OTSG) and high pressure mine water heaters for thermal enhanced oil recovery(EOR) and mining operations
• Combination H2S incinerators/fired heaters
• Liquid metal heaters to heat NaK and other metals
• Potassium liquid heater
• Refinery heaters for various refinery operations such as crude oil heating, platforming, naphtha vaporization, and coker feed heating
