The scope of work was complex elaboration of two numbers of steam boilers reconstruction with steam capacity of 496 t/ h with following scope of supplies and services:
Complete designing & engineering, manufacturing drawings, technical procedure of dismantling and assembly of burners, testing and commissioning of boilers.
Designing and engineering of boilers 3, 4 reconstruction at Thermal Power Station Mehardeh (Syria) was worked out on the basis of tender documents issued dated 24-05-2004 by the Ministry of Energy Syrian Arab Republic.
Originally both oil fired Units 3 and 4 with natural circulation were supplied by SGP company. Boilers were commercially operated (commissioned) gradually in 1988 and 1989. Subsequently both boilers were modified to gas and oil firing.
After reconstruction boilers are characterised with following designed parameters:
Boiler Capacity | % | 50 | 75 | 100 |
Boiler Thermal Capacity | MWt | 202 | 294 | 390 |
Turbine capacity (electrical) | MWe | 82,5 | 123,8 | 165 |
Boiler Steam Capacity | kg/s | 66,5 | 100 | 137,5 |
Superheated Steam Pressure | barg | 126,6 | 128 | 130,1 |
Superheated Steam Temperature | °C | 541 | 541 | 541 |
Reheated Steam Flow | kg/s | 61,1 | 92,2 | 126,4 |
Reheated Steam Pressure | barg | 15,4 | 23 | 31 |
Reheated Steam Temperature | °C | 529 | 541 | 541 |
Feed Water Temperature | °C | 200 | 221 | 238 |
In order to achieve maximum possible boiler power K3 and K4 following major modifications have been made:
