Types of HRSG Cleaning - Alaqua Machinery

A heat recovery steam generator (HRSG) is a key component of a gas turbine combined cycle power plant with high thermal efficiency and low CO2 emissions. An HRSG is a heat exchanger that extracts a significant amount of heat from a gas turbine's exhaust gases. The heat is recovered as steam, which is used to power a steam turbine that generates electricity.

Finned tubes with outstanding heat-transfer capability are used in the HRSG's heat-transfer tubes. The equipment's footprint is decreased by using a small design. Additionally, within the HRSG, Selective Catalyst Reduction (SCR) equipment is installed, which reduces the nitrogen oxide concentration of the exhaust gases emitted into the environment.

Energy is lost in thermal oxidizers, gas turbines, and other heat generators. Heat Recovery Steam Generators (HRSG) are utilized to create steam in order to recover energy and use it for other purposes.

HRSG systems may be found in a wide range of commercial and industrial settings. HRSG systems are most typically employed in major energy projects, cycle power plants, and even institutions. Schools may use recovered energy to power their campus, heat spaces, and supply hot water to residents.

Alaqua is a processing equipment supplier for crystallizer, heat exchanger, evaporator, solvent recovery, distillation and spray dryers for various industries such as food, pharmaceutical, chemical, environmental, and power generation industries.

HRSG Cleaning Types

High-pressure water blasting, carbon dioxide (dry ice) blasting, grit blasting, and pressure wave cleaning are some of the most common forms of cleaning technologies on the market. Because each has its unique set of benefits, a plant's selection is made on an individual basis.

• Pressure Wave Cleaning
• High Pressure Water Blasting
• Grit Blasting
• Dry Ice Blasting

Pressure Wave Cleaning

A hose is fed into a heat recovery steam generator for pressure wave cleaning. The engineer uses a computer to manage the ethane-oxygen gas discharged inside the system as it moves about inside. The impurities inside the HRSG are rattled by the gas, which dislodges the debris. It sinks to the bottom of the HRSG, making cleaning easy.

High Pressure Water Blasting

High pressure water blasting (also called hydrojetting or high-pressure cleaning) removes surface debris and pollutants using high-speed, pulsing water produced by a water jet. Even the most tenacious coatings or process contaminants cannot withstand the energy generated by ultra-high pressure hydroblasting. High-pressure hydroblasting equipment is not only effective in a wide range of industries, but it is also ecologically benign, minimizing carbon emissions.

Grit Blasting

Abrasive grit blasting, often known as sandblasting, is a process that uses pressured water, steam, or compressed air to push an abrasive media (material). The blasting material can be used to smooth rough surfaces, roughen smooth surfaces, shape a surface, or eliminate impurities from the surface. 

Blasting can use a variety of media, some of which are very abrasive and others that have a mild impact. The choice of media is influenced by a variety of components. Often, sample processing is required before deciding on the final media type, size, and equipment for the grit-blasting process.

The following are examples of commonly used abrasives:

• Steel grit
• Crushed glass
• Aluminum oxide
• Plastic
• Baking soda

Dry Ice (CO₂) Blasting

Dry ice blasting is widely regarded as one of the most effective cleaning methods for HRSGs for a variety of reasons. Sandblasting and high pressure water blasting, in most situations, produce a secondary waste stream that adds to the waste stream.

Cleaning up additional garbage adds to a project's total cost and time. Dry ice blasting is an ecologically friendly and FDA-approved procedure that doesn't encourage corrosion or abrasion. There is no secondary trash created by CO23 blasting since it does not employ abrasives or excessive water. This decreases both the cost and the time it takes to complete the procedure.

Effects of Fouling on HRSG Component Performance

As a result of routine activities, trash and debris accumulate over time in day-to-day operations. Heat-rate deterioration, loss of steam generation, corrosion, and decreased heat transfer efficiency can all occur as a result of this accumulation over time. These problems result in a reduction in producing capacity and, as a result, revenue.

Maintenance is the most effective strategy to preserve your equipment's value and productivity. Cleaning services from HRSG are a long-term investment in your operating productivity and equipment longevity. To deliver ecologically safe and highly effective cleaning solutions, trained personnel employ cutting-edge technology.

Features of HRSG

Major attractive features of HRSG’s are that they:

• Have high reliability and high performance
• Are highly cost-effective

ALL ABOUT THE PROCESS OF EVAPORATOR MANUFACTURING

The first step in the whole process of evaporator manufacturing is even more important than the manufacture of evaporators itself. The step is designing the evaporators. We work very hard and closely with our team so that the evaporators we manufacture fulfill the requirements of the industry and the production process. The procedure of starting a new evaporator project starts with the meeting between the staff of the technical team and application engineers. In the meeting, the team discusses the process, discusses the product, and about the production goals for the plant. After that, the inspection of the equipment happens to gather data. For example, if we are launching a Greenfield project so our team will discuss all the critical steps carefully for developing the process.

The data gathered and the gained information in the technical team meeting is used in the pre-engineering effort so that the development of the right evaporator process can happen. Firstly we create the concept of an evaporator system that can fulfill the objectives of the business according to the uptime with regards to the efficiency, cleanability, operability, and production volumes. After that, we move forward to the specifics of the evaporators. For the complete evaporator system, the whole work of manufacturing the evaporators is processed through the engineering, mechanical engineering, and design work departments. The manufacturing of evaporators requires forming an idea of the evaporator system and according to that, we arrange the specialty materials required for the construction of evaporators.

Sometimes, the evaporators are also constructed according to the requirements of earthquake zones. The basic engineering drawings and the detailed documents about the designing of the evaporators are required for contractors to proceed with the construction of the evaporator system. Before constructing the evaporators, the technical team and contractors discuss the design and make some changes if they are required. The guesswork is not allowed in the foundations, structural support, and the requirements of the installation and launching of a new evaporation system. The whole process of manufacturing the evaporators should follow the processing line seamlessly.

After the pre-engineering the package is finalized, the process of manufacturing the evaporators is carried out. Once the equipment process is completed, our team works on the installation part. Taking care of every single detail of the evaporator equipment at the time of installation is very important. Once the manufacturing of the evaporators completes, the technical team and engineers are always available for any requirements of further assistance. Alaqua is a US corporation and we have experience of over 20 years in manufacturing evaporators, crystallizers, and distillation systems in numerous applications. If you are also thinking about getting a new evaporator for your industry then you can contact us on www.alaquainc.com our website for more information.

ALL ABOUT DISTILLATION EQUIPMENT BY ALAQUA

Distillation is the process of separating the components or substances from a mixture by using selective boiling and condensation resulting from different boiling points. Distillation may result in complete or partial separation that increases the concentration of selected components in the mixture. Examples of uses of distillation include purification of alcohol, desalination, crude oil refining, and making liquefied gases from the air.

Distillation Equipment usually forms part of a larger chemical process and is thus referred to as a unit operation. Distillation of fermented solution to produce beverages with higher alcohol content has been in use since ancient times. Distillation has several uses in various commercial forms. It is used to separate crude oil into more fractions for specific uses such as transport, power generation and heating. Water is distilled to remove impurities, such as salt from seawater. Air is distilled to separate its components –notably oxygen, nitrogen and argon for industrial use.
