LESSONS LEARNT
CE certificate from a notified body. Proheat used Royal Sun Alliance (RSA). This demonstrates design checks have been carried out and the unit is safe for operating at the design pressures with the materials used.
Carrying out a separate G17 approval for the preheater itself is meaningless (design approval and appraisal covers all aspects of the site construction).
2 Stage burner head. Re-designed as a result of problems following commissioning at Little Burdon.
2 Stage burner head is split 50% - 50% of duty.
Commissioning on site time took 81 man days of Proheat staff time. (January – March 2017).
Electric preheater for Let Down Unit serving the Proheat units has caused the Proheat units to trip. To be carefully considered for future projects.
