Risk Diagnosis Service that BHK Can Provide as a Boiler Manufacturer

As a manufacturer of utility and industrial boilers, BHK appropriately diagnoses your boilers to provide the optimized maintenance plans, contributing to the consistent long-term operation of your boilers.

Saving Maintenance Cost

This chart represents estimated financial loss during a power plant outage period. This calculation is based on electric power sold in Southeast Asia.
When a 500MW power boiler stops for 10 days due to an unanticipated accident, the financial loss is presumed to be no less than $10 million.

financial loss

Since 1996, we have applied the life assessment system to boiler plants in Japan, taking into account time-related degradation factors. The application of RBM diagnosis for boilers greatly decreases the frequency of unanticipated accidents, reduces long-term financial losses and avoids harm to the environment and staff.
