Cogen’s turnkey pre-engineering and steam blow services were key for the startup of our new coal-fired boilers.  The pre-engineering and detailed procedures submitted prior to the actual work ensured that the multi-million pound-per-hour steam blows were successfully completed in ten days instead of the months it would have taken going the conventional route.
