HORA Desuperheater Delivery Record: Four Desuperheater Types Supplied to an SK Power Plant in Korea

HORA Desuperheaters Delivered to an SK Power Plant in Korea

The heart of temperature control in high temperature, high pressure steam systems, supplied by VALVEPARK

In power plants and industrial plants, steam temperature control is a critical factor that determines both stable operation and overall efficiency.

In systems that handle high temperature, high pressure superheated steam in particular,

a device that lowers the steam temperature precisely to match the operating conditions is essential.

This post introduces the HORA Desuperheaters that VALVEPARK actually delivered to an SK affiliate power plant in Korea.

※ For security reasons and at the customer request, the specific plant name and project details are not disclosed.

What Is a Desuperheater?

A Desuperheater is a device that sprays finely atomized cooling water into superheated steam

in order to bring the steam temperature down to the required level.

In simple terms, it works on the following principle.

High temperature superheated steam + spray water → fine droplets sprayed and mixed → spray water evaporates → steam temperature drops

The steam can only be cooled to the target temperature reliably when the cooling water is fully atomized and evenly mixed into the steam, so

a desuperheater should never be thought of as a simple water spray device.

In a real plant, steam temperature, pressure, flow rate, spray water conditions, available installation space and load variation all have to be considered together

when selecting and designing the right type of Desuperheater.

HORA likewise offers a broad range of Desuperheater solutions for power generation and industrial plants,

with designs that cope with steam temperatures of up to 600℃ and high pressure conditions depending on the product.

Which HORA Desuperheaters Are Available?

HORA supplies several different Desuperheater designs to match site operating conditions and required performance.

This delivery covered the following four types of HORA Desuperheater.

1. Injection Lance

The Injection Lance reaches into the steam pipe and sprays cooling water inside it.

Spray water is injected into the steam flow inside the pipe, mixes with the steam, and lowers the steam temperature as it evaporates.

An injection device that reaches inside the steam pipe and sprays cooling water

That is the simplest way to remember it.

2. Steam Assisted Atomizer

The Steam Assisted Atomizer uses auxiliary steam to atomize the spray water even more finely.

By breaking the spray water into very small droplets that mix rapidly with the hot steam, it is designed to deliver efficient cooling and accurate temperature control.

How evenly the spray water mixes with the steam and how quickly it evaporates are decisive factors in Desuperheater performance, so

this atomizing technology plays an important role as well.

3. Venturi Desuperheater

The Venturi Desuperheater uses a venturi section to make the steam flow and the spray water mix effectively.

Its defining feature is that the geometry of the steam passage itself is used to mix the spray water thoroughly into the steam.

It is one of the Desuperheater designs used where the mixing and evaporation process matters most.

4. Multiple Nozzle Desuperheater

As the name suggests, the Multiple Nozzle Desuperheater sprays cooling water through several nozzles.

Rather than concentrating the spray water in a single nozzle, the flow is distributed across multiple nozzles so that it mixes with the steam more uniformly.

This multiple nozzle approach suits plants with high steam flow rates or tight temperature control requirements.

How Do the Four Desuperheaters Differ?

Product Type	Key Characteristics
Injection Lance	Injects spray water directly inside the pipe to control steam temperature
Steam Assisted Atomizer	Uses auxiliary steam to atomize the spray water for effective mixing with the steam
Venturi Desuperheater	Uses a venturi structure to improve steam and spray water mixing and cooling efficiency
Multiple Nozzle Desuperheater	Distributes and sprays the water evenly through multiple nozzles for precise temperature control

Item	Key Specification
Function	Optimizes system performance through precise temperature control and effective cooling
Pressure Rating	Up to PN400
Temperature Range	Up to 600℃
Medium	Steam, Water
Main Applications	Power generation, pulp and paper, chemical and petrochemical, metals

HORA official product literature also lists the Desuperheater range with a pressure rating of up to PN400 and

a temperature range reaching 600℃.

Because this equipment handles such high pressures and temperatures, selecting a product takes more than checking a size:

a technical review based on the actual operating conditions is what matters.

VALVEPARK Delivers HORA Desuperheaters to a Korean Power Plant

For this project, VALVEPARK delivered HORA Desuperheater products to an SK affiliate power plant in Korea.

The specific plant name and the project details cannot be disclosed for customer and project security reasons, but

we do hold a delivery record of actually supplying HORA Desuperheaters to a power generation site in Korea.

What makes this delivery meaningful is that it was not a single identical product, but a range of HORA Desuperheaters:

Injection Lance

Steam Assisted Atomizer

Venturi Desuperheater

Multiple Nozzle Desuperheater

all supplied for the same project.

Steam systems in power plants run under demanding conditions, so it is important to check the product specifications accurately and

to select a product that matches the required conditions.

we can also handle technical questions like these.

Industrial Valves Take Engineering: VALVEPARK Is With You

As this HORA Desuperheater delivery to a Korean power plant shows, industrial valves and equipment used in plants

depend far more on accurate product selection and technical review than on the purchase itself.

As an official HORA distributor, VALVEPARK backs product supply with specialist engineer support, covering everything from product selection to

engineering, delivery and maintenance, working through the solution your site needs together with you.

If you need a HORA Desuperheater for a high temperature, high pressure steam system, or have questions about purchasing or

maintaining HORA products, please contact VALVEPARK.

We will review the product that fits your site conditions and provide the engineering support you need.
