Modernization of the ignition and gas supply systems for a coal-fired power plant
A coal-fired power plant in Germany with an electrical output of 500 MW, which began operations in 1986, was upgraded to meet current technical requirements as part of a modernization project. The project focused on upgrading the ignition system and modernizing the gas supply system, including pressure regulation and safety-critical components.

Our solution
Hegwein, a DURAG GROUP company, implemented a comprehensive modernization plan for ignition and gas supply systems. This involved replacing existing components with modern systems and completely upgrading the gas supply all the way to the individual igniters. Particular attention was paid to safe pressure reduction, precise pressure regulation, and the integration of additional safety measures within the gas supply system.
Project scope
- Replacement of 20 igniters, each with a capacity of 120 kW (LPG)
- Installation of a new medium-pressure station with a design pressure of 16 barg for safe pressure reduction from 190 mbarg
- Replacement of 20 individual gas trains
- Comprehensive renewal of the gas supply piping system
- Expansion of the gas supply to include additional safety valves
Benefits for the customer
Even in existing plants, targeted modernization contributes significantly to improving efficiency and safety. The measures implemented brought the ignition systems, gas supply, and pressure regulation up to the current state of the art and sustainably increased operational safety.
This project exemplifies how even older power plants can be adapted to today’s safety and reliability requirements by modernizing key systems – thanks in part to engineering expertise, state-of-the-art systems for combustion and safety monitoring, and customized solutions from Hegwein.
