【 Good News 】 Viti has successfully won the bid for the Huaneng Tai 'an 2× 9F-class gas-steam combined cycle cogeneration project!

Recently, Viti Fluid Control Co., Ltd. successfully won the bid for the steam trap equipment of Huaneng Tai 'an 2× 9F-class gas-steam combined cycle cogeneration Project. It will provide key steam traps and manual stop valves and other complete sets of equipment for this project. This is another significant performance breakthrough for Viti in the field of gas-steam combined cycle power generation, fully demonstrating the company's comprehensive strength and market competitiveness in the field of valves for harsh working conditions.

Project Overview: Heavy-duty Gas Turbine Demonstration Project in Shandong Province

The Huaneng Tai 'an Gas Turbine Project is located in the Dawenkou Industrial Park, Dayue District, Tai 'an City. It is planned to build two 9F-class "one-to-one" gas-steam combined cycle units, with a total installed capacity of approximately 1 million kilowatts. As a demonstration project of heavy-duty gas turbines in Shandong Province and the first heavy-duty gas turbine project in Tai 'an City, the total investment of the project amounts to 2.4 billion yuan. The net efficiency of the combined cycle can reach 62%, and the energy efficiency is 40% higher than that of traditional coal-fired units. It has the dual advantages of efficient power generation and clean heating.

After the project is put into operation, it will effectively enhance the peak shaving capacity of the regional power grid, enrich the peak shaving resources of the Shandong power grid, and at the same time reduce emissions and energy consumption from the source, injecting new impetus into the green transformation of Tai 'an's energy structure and the green, low-carbon and high-quality development of the entire province.

Strict procurement requirements

This procurement involves two sets of pneumatic steam traps and manual stop valves for the units, with extremely high technical requirements

• The main steam and hot section steam traps are made of A335P91 high-temperature alloy steel, suitable for high-temperature and high-pressure steam working conditions.

• The cold section steam trap is made of 12Cr1MoVG material.

• Suppliers must provide at least two supply records of steam traps for domestic thermal power units with a single-unit capacity of 300MW or above in the past ten years

• The purchaser, China Huaneng Group, has strict requirements for the qualifications of suppliers, product quality and technical standards

    With its outstanding product quality, complete technical qualifications and rich experience in the power industry, Viti stood out among many competitors and successfully won the bid.

The core technical advantages of Vittey steam traps

The Viti high-pressure differential steam trap is specially designed for harsh working conditions such as thermal power and gas turbine combined cycles, and has the following core advantages:

• Integral free-forged valve body: Higher strength than die forging, beautiful structure, and high reliability;

• Ultra-high hardness pressure reducing sleeve: Through three levels of pressure reduction including expansion, collision and offset, the pressure can be reduced by 70%, effectively avoiding cavitation and erosion.

• Super-thick hard alloy surfacing: Resistant to erosion and high temperatures. After the valve is fully opened, the valve core is completely protected by the pressure-reducing sleeve and is not subject to the erosion of the medium.

• Replaceable valve seat design: The valve can be replaced and maintained online without being cut off from the pipeline, significantly saving maintenance time.

• Non-rotating valve stem design: Minimizes the wear of the valve stem on the packing and extends the sealing life.

Performance as proof: Continuous service to Huaneng Group

Vita has been successfully applied in hundreds of power generation enterprises affiliated with China Huaneng Group, China Datang Group, China Huadian Group, etc. This successful bid for the Huaneng Tai 'an gas turbine project has further consolidated Viti's market position in the gas-steam combined cycle power generation field and also accumulated new achievements for the company in the clean energy power generation sector.

Viti - based on German technology and supported by global manufacturing, continuously provides reliable fluid control solutions for China's clean energy power generation industry.
