Conventional Power Plant (Coal, Oil and Gas Fired)

Plant Description

In a conventional thermal power plant, fossil fuels, either coal, gas or oil, are burned in a large water-cooled furnace. Steam generated in the furnace is delivered to heat exchangers for superheating. This superheated steam is used to drive a steam turbine generator from where the electricity produced is sent through a high voltage switchyard to the electrical grid system.

Coal-fired plants are the most common, and comprise extensive and sophisticated coal storage and handling systems.

Kentz Capabilities and Experience

Where the client has chosen to award the contract on a EPC (Engineer, Procure & Construct) basis, Kentz typically enters into consortium with an established OEM for the power plant prime equipment such as coal handling plant, boilers, steam turbines. Kentz takes responsibility for the complete Balance of Plant (BOP) for all electrical, control & instrumentation systems. Complete site installation works for electrical and instrumentation scope is performed by Kentz.

Balance of Plant scope for electrical, control and instrumentation systems typically comprises the following:

• Diesel generators
• Emergency shutdown systems
• Main plant transformers
• Low, medium and high voltage switchgear
• Station mimic panels
• Batteries and UPS systems
• Generator circuit breakers
• Small power and lighting systems
• Grounding systems
• Fire and gas detection systems
• Switchyard control and protection systems
• SCADA systems
• Distributed control systems
• CCTV and complete plant security systems

Engineering, Procurement and Construction

Kentz performs the complete Balance of Plant (Electrical) engineering and procurement functions. Engineering of the plant is carried out in close consultation with the OEM.

Procurement and expediting roles involve extensive logistical challenges due to worldwide sourcing of equipment and often challenging and remote locations of project sites. Kentz employs the services of many Third Party Inspection Companies to ensure all equipment supplied meets all applicable Regulatory Standards and Project Specification requirements.

Construction and commissioning is largely executed on a self-perform basis by Kentz. Kentz has developed many in-house construction and commissioning management and tracking systems that have been adopted by many key clients.

Construction and commissioning involves preparation of all required handover documentation presented to clients.

Following handover of the plant, Kentz provides site-based warranty engineers for the duration of the warranty period.
