CASE STUDY

SUEZ GULF
POWER PLANT

EGYPT

SUEZ GULF POWER PLANT

2 x 350 MW (2 Boilers x 1,065 T/hr) firing a mixture of Fuel Gas and Heavy Fuel Oil
Problem
Fouling of superheaters and economisers resulting in efficiency loss. After Therma-Chem Treatment A TÜV inspection revealed that hard scale formations on the superheater and stringer tubes were removed by FS12. This resulted in an efficiency increase of 1.1% for the limited duration of the 33-day trial and an emissions reduction of c.40 tonnes of CO2 per day. Please see the attached TÜV reports for further information on the condition of the boiler after 33 days of Therma-Chem treatment.
