Uniquip Fired Heaters


The involvement of Uniquip with fired heaters dates back to 1957, when K.C. Bottomley, one of the founding partners of the company, returned to Australia from the United Kingdom. Over the period 1957-1960, he acted as the process designer/sales representative for Birwelco (UK), who was the Commonwealth Licensee for Petrochem (USA). Nine small units were sold and built in Australia in that period, all of the vertical cylindrical design.

In 1960, John Lysaght (Australia), with a large fabricating facility in Newcastle, became the Australian manufacturing licensee for Petrochem, with Uniquip continuing to act as process designer/sales representative. This continued until 1972 when Lysaght closed its Newcastle works. Over the 1960-1972 period, 59 heaters were supplied, of which 28 were vertical cylindrical and 31 horizontal.

After 1972, Uniquip continued to design and sell fired heaters, but without any overseas connection.

On July 1, 1986 Uniquip Pty Limited was acquired by Plenty – H&M Pty Limited, which then changed its name to Plenty Uniquip Pty Ltd. During the period 1973-1993, 36 heaters were supplied of which 15 were vertical cylindrical and 21 horizontal.

During 1993, a non-exclusive licence arrangement commenced between Plenty Uniquip and Lummus Heat Transfer BV of The Hague and since that time an additional 28 new heaters have been ordered, 11 vertical cylindrical, 4 horizontal cylindrical convective, 1 horizontal cylindrical start-up heater, 1 horizontal cylindrical oil heater, one horizontal cylindrical glycol heater and 10 horizontal. In addition, 5 fired heater design revamps have been undertaken, 2 each with Ampol and BP Brisbane and 1 with Western Mining.

In April 2002, the Uniquip portion of Plenty Uniquip was sold to Uniquip Engineering who then assumed responsibility for Fired Heaters, commencing with the completion of the Shell Clyde Refinery Job #C0134.

The Uniquip Fired Heaters features a unique design that utilises firetube elements. A range of fired heater products is available including horizontal hot oil heaters and Incinerators, FCC Fired Heaters, Steam Superheaters., Water Bath Heaters, Direct Fired Reboilers and Brown FintubeR Exchangers.

The design of Uniquip Fired Heaters incorporates the following features:

  • Burners are selected for correct flame pattern, stable operation and maximum turndown
  • Adequate clearance between flame and tube coil to avoid flame impingement
  • Vertical cylindrical or horizontal box type designs
  • Natural or forced draught burners for oil, gas or dual-fuel operation
  • High quality refractory brick, castable or ceramic fibre
  • Variety of design options to achieve the highest economic efficiency
  • Extensive experience in single or multi-burner forced draught operation with full automatic or semi-automatic control

Typical installations for refinery duty include FCC Fired Heaters with design efficiency up to 84%, depending on the fuel utilised. Such heaters are fittedwith dual fuel natural draught burners with noise attenuation, sootblowers and Schedule 80 alloy tubing in bothradiantand convection zones, with all welds fully radiographed.

Offshore, typical installations include heaters for hot oil service (260 deg C), fired with forced draught burners and fully packaged with all instrumentation.
