AITESA is proud to support this project with the design, manufacturing and supply of a new generation HRSG, including upgraded recirculation pumps, redesigned inlet and outlet flue gas ducts, an improved cleaning ramp system, and the reinforcement of the boiler support structure.

We thank 𝐓𝐎𝐏 𝐒𝐓𝐑𝐔𝐂𝐓𝐔𝐑𝐄𝐒 and 𝐒𝐄𝐍𝐄𝐋𝐄𝐂 for their collaboration and trust.

Day 1 included site and equipment inspection, as well as the start of dismantling works for the existing boiler.

An important first step towards a safe, reliable and efficient installation.

As pressure and temperature fall, oxygen and residual moisture can create the conditions for 𝐢𝐧𝐭𝐞𝐫𝐧𝐚𝐥 𝐜𝐨𝐫𝐫𝐨𝐬𝐢𝐨𝐧 in drums, evaporators, economizers and steam circuits.

The impact often appears later, during restart: longer preparation time, additional flushing, contamination of the water steam cycle, damage to protective magnetite layers or higher tube reliability risk.

That is why 𝐩𝐫𝐞𝐬𝐞𝐫𝐯𝐚𝐭𝐢𝐨𝐧 should be defined before the shutdown, not once the equipment has already cooled down.

For short outages, wet preservation may be enough if water chemistry is properly controlled. For medium outages, nitrogen blanketing can help reduce oxygen ingress. For extended shutdowns, dry preservation is usually the most robust option, although it requires more preparation and a clear restart plan.

The key decision is to match the preservation method to the expected outage duration and the operational requirements of the next startup.

A boiler is protected when its internal environment is controlled.

At AITESA, we work with industrial boilers, HRSGs and heat recovery equipment designed for long term operational reliability, including shutdown and preservation considerations that directly affect equipment lifetime and restart performance.

In a thermosolar plant, heat represents a significant opportunity energy recovery

This was the challenge AITESA addressed in a 50 MW thermosolar plant in China. The plant had significant thermal flows available, and the objective was to make better use of them to improve overall energy efficiency within the existing power cycle.

AITESA implemented a heat recovery boiler with an integrated heat exchange train designed to improve energy recovery across four key points of the cycle:
• 𝐄𝐜𝐨𝐧𝐨𝐦𝐢𝐳𝐞𝐫: Preheated the high pressure feed water (over 100 bar) with the remaining HTF energy before steam generation.
• 𝐒𝐭𝐞𝐚𝐦 𝐆𝐞𝐧𝐞𝐫𝐚𝐭𝐨𝐫: Converted the recovered heat into high-pressure steam for the main power cycle.
• 𝐒𝐮𝐩𝐞𝐫𝐡𝐞𝐚𝐭𝐞𝐫: Increased the steam energy level before turbine inlet.
• 𝐑𝐞𝐡𝐞𝐚𝐭𝐞𝐫: Reheated the steam after the first turbine expansion at lower pressure (over 20 bar) to support a second expansion stage.

𝐓𝐡𝐞 𝐫𝐞𝐬𝐮𝐥𝐭: an increase in overall efficiency from 35.5% to 37.5%.

For a 50 MW asset, that improvement represented 7 GWh per year of additional recovered energy that would otherwise remain unused. In thermosolar plants, this type of opportunity often starts by reviewing how the boiler and heat exchange train use the available heat across the steam cycle.

中国 50 MW 光热电站如何通过余热回收增加 7 GWh 发电量

在光热电站中，热能代表着巨大的能源回收机会。

这正是 AITESA 在中国某 50 MW 光热电站中所解决的挑战。该电站拥有大量的可用热流，其目标是更有效地利用这些热流，以提高现有动力循环的整体能源效率。

AITESA 实施了一套带有集成换热系统的余热锅炉，旨在优化循环中四个关键节点的能源回收：
• 省煤器：在产生蒸汽前，利用剩余的导热油能量预热高压给水（压力超过 100 bar）。
• 蒸汽发生器：将回收的热量转化为高压蒸汽，用于主动力循环。
• 过热器：在进入汽轮机之前提高蒸汽的能量等级。
• 再热器：对第一级汽轮机膨胀后的低压蒸汽（超过 20 bar）进行再热，以支持第二级膨胀。

结果：整体效率从 35.5% 提升至 37.5%。

对于一个 50 MW 的资产而言，这种改进意味着每年额外回收 7 GWh 原本会被浪费的能量。在光热电站中，这类优化机会通常始于重新评估锅炉和换热系统如何在蒸汽循环中利用可用热能。

Following last week’s post on how different factors can affect air cooler performance, we wanted to share three project references where those same principles become engineering decisions.

Each project was driven by different needs and technical challenges, but they all share the same focus: 𝐨𝐩𝐭𝐢𝐦𝐢𝐳𝐞𝐝 𝐬𝐢𝐳𝐢𝐧𝐠, 𝐦𝐞𝐜𝐡𝐚𝐧𝐢𝐜𝐚𝐥 𝐢𝐧𝐭𝐞𝐠𝐫𝐢𝐭𝐲, 𝐧𝐨𝐢𝐬𝐞 𝐜𝐨𝐧𝐭𝐫𝐨𝐥, 𝐚𝐜𝐜𝐞𝐬𝐬𝐢𝐛𝐢𝐥𝐢𝐭𝐲, 𝐭𝐞𝐬𝐭𝐢𝐧𝐠, 𝐚𝐧𝐝 𝐪𝐮𝐚𝐥𝐢𝐭𝐲 𝐝𝐨𝐜𝐮𝐦𝐞𝐧𝐭𝐚𝐭𝐢𝐨𝐧.

Between 2:00 PM and 5:00 PM, three factors converge at once: peak process heat load, maximum air temperature, and minimum air density. That combination alone can cut thermal capacity by up to 44%.

And that's just one piece of the puzzle. Hot air recirculation, equipment placement, fan control strategies, and the real economics of those critical hours all play a role — and most of them go undetected until the process is already constrained.

At AITESA, we've put together a full technical breakdown of how air variability affects cooler performance, and what levers actually move the needle.

𝐄𝐏𝐂 𝐏𝐫𝐨𝐣𝐞𝐜𝐭 – 𝐏𝐚𝐜𝐤𝐚𝐠𝐞𝐝 𝐁𝐨𝐢𝐥𝐞𝐫 𝐟𝐨𝐫 𝐭𝐡𝐞 𝐂𝐡𝐞𝐦𝐢𝐜𝐚𝐥 𝐒𝐞𝐜𝐭𝐨𝐫

When a plant needs to replace a steam generation unit, the biggest constraint is usually shutdown time. At AITESA, we tackle this challenge at the workshop by delivering preassembled packaged solutions that significantly reduce site work and accelerate commissioning.

We are currently manufacturing a 𝐩𝐚𝐜𝐤𝐚𝐠𝐞𝐝 𝐬𝐚𝐭𝐮𝐫𝐚𝐭𝐞𝐝 𝐬𝐭𝐞𝐚𝐦 𝐛𝐨𝐢𝐥𝐞𝐫 𝐟𝐨𝐫 𝐭𝐡𝐞 𝐜𝐡𝐞𝐦𝐢𝐜𝐚𝐥 𝐢𝐧𝐝𝐮𝐬𝐭𝐫𝐲 as part of an EPC project. The entire unit is being assembled and pre-mounted as a single module ready for shipment, helping reduce installation risks and shorten the shutdown window.

𝐃𝐞𝐬𝐢𝐠𝐧 𝐚𝐧𝐝 𝐬𝐩𝐞𝐜𝐢𝐟𝐢𝐜𝐚𝐭𝐢𝐨𝐧𝐬

The unit has been designed to operate at 256 °C and 44 kg/cm², incorporating:

• Finned tube waterwall for radiant heat absorption
• Tube screen acting as a transition between radiant and convective sections
• Upper steam drum for steam and saturated water separation
• Lower drum for saturated water circulation
• Convective tube bundles
• Supporting structure, flue gas ducting, and sealing systems
• Inspection windows and access doors for operation and maintenance
