Process Air Heater

PROCESS AIR HEATER – SHELL & TUBE HEAT EXCHANGER

Technobel Process Air Heaters and Shell & Tube Heat Exchangers are custom-engineered for efficient transfer of thermal energy between process gases, air, liquids, steam, or other heating media. The equipment consists primarily of a pressure-containing shell, tube bundle, tube sheets, process connections, supports and associated internal components. Shell-and-tube construction is widely used in chemical, refinery, power and general process industries because it can be engineered for demanding pressure and temperature conditions.

       The tube bundle provides a large heat-transfer surface within a relatively compact equipment envelope. One process medium flows through the tubes while the second medium passes through the shell side, allowing heat transfer while keeping the two streams physically separated. Tube diameter, tube length, number of tubes, tube pitch and flow arrangement can be selected according to the required thermal duty. Materials of construction can be selected according to process temperature, pressure, corrosion characteristics and customer specifications. Carbon steel, stainless steel and various alloy materials can be considered depending on the application.

       Tube sheets are precision drilled and the tubes may be expanded, welded, or expanded and seal-welded depending on the service requirement and applicable specification. The equipment can be manufactured in vertical or horizontal configurations to suit plant layout and process requirements. Fixed tube-sheet, U-tube and removable-bundle arrangements can also be considered according to thermal expansion, cleaning and maintenance requirements.
