Increasing trends in highly flexible power generation and the need for energy in proximity to end users is expanding the role of small scale power plants for distributed generation (DG), cogeneration and combined heat and power (CHP) technologies. The ideal fit for these fast, flexible technologies is typically in the capacity range of less than 1 kW to 100 MW. Equipment can be packaged as modular systems which require only a small footprint with minimal field erection.

Small scale combined cycle gas turbine (CCGT) technology, with or without integration of renewables, is well-suited for producing decentralized DG power. However, there are some limitations with CCGT plants for small scale power generation (<100 MW) when they incorporate traditional horizontal or vertical HRSG drum boilers. Drum boilers require periodic blowdown for removal of suspended solids and bottom sludge and this requires the use of chemicals such as hydrazine or phosphates in addition to replenishment of make-up water. Distinct economizer, evaporator and superheater zones within a HRSG drum boiler require associated piping, instruments and controls. In addition, the high-pressure drum limits temperature increases upon startup resulting in long start-up times.
John Cockerill Energy, formerly known as Cockerill Maintenance & Ingénierie (CMI), has introduced its Once Through Boiler (OTB) which eliminates several of the drawbacks associated with drum type HRSGs. Unlike the traditional HRSG boiler design where economizer, evaporator and superheater sections are interconnected with a high-pressure steam drum, in the OTB design water is heated, vaporized, and superheated in a single serpentine tube. With the OTB design, boiler efficiency is improved as there is no approach temperature associated with a high-pressure drum and flexibility increased with the inclusion of fast start and dry run capability. As delivered and installed, the OTB provides the smallest footprint and lightest weight making the OTB ideal for simple cycle conversions to combined cycle as well as floating power plants. Other key features include a simplified boiler design with maximum flexibility, controlled GT emissions in open cycle and fast steam cycle startup and shutdown capability.
During this informative webinar, Pascal Fontaine and Caleb Lawrence of John Cockerill, will discuss key features, applications, and benefits of the OTB design. Specific topics to be addressed will include:
How OTB provides for flexible operations, fast steam cycle start-up and shutdown
How OTB provides stability of operation at low gas turbine load while maintaining steam temperature
How OTB simplicity of design provides lowest life cycle cost
How OTB can control GT emissions in open cycle
In addition, case studies for existing GT projects will be discussed.
Who should attend:
Power Project Developers
Utilities, Power Plants & CHP
Gas Turbine OEMs
Flexible CCGT units
Decentralization & Renewables Integrators
Attendees can ask additional questions which will be covered during the Q&A session at the end of the webinar.
