USING CONDENSATE FOR AIR PREHEATER

We use flash steam and condensate of the steam air heater to pre-heat the process air and save energy.
Returning of water without any flash steam to the condensate tank

Some advantages to select Basaranlar Proses steam air heater:​

• Aerodynamically suitable tubes
• Low pressure drop, as well as minimal fouling and contamination
• Large heat-transfer coefficients, resulting in small heat-exchange surface areas
• Good corrosion protection by hot-dip galvanizing
• Compact design that enables good utilization of limited floor space
• Maximum life cycle
• On going optimization of the finned-tube system by computational fluid dynamics (CFD) simulation

SAFETY EQUIPMENTS

• Steam Trap: A steam trap’s most important job is to quickly discharge condensate that has formed in steam distribution lines, steam tracers, and in steam air heater. A steam trap must also be able to save energy by preventing steam leaks and by discharging non-condensing gases such as air.
• Vacuum Breaker: High pressure can be executed during the using of the steam air heat exchanger or steam coil equipment but when they stopped steam air heat exchanger will be cool that will cause condensation of the steam. Because of the volume decreasing which is caused by steam-water translation inner pressure will decrease and vacuum effect will execute.
• Strainers: These devices are frequently forgotten about in steam systems, often, it seems, in an effort to reduce installation costs. Pipe scale and dirt can affect control valves and steam traps, and reduce heat transfer rates. It is extremely easy and inexpensive to fit a strainer in a pipe, and the low cost of doing so will pay dividends throughout the life of the installation. Scale and dirt are arrested, and maintenance is usually reduced as a result.

STEAM AIR HEATER FOR COMBUSTION AIR

The steam air heater  or steam coil preheats the combustion air before entering the air preheater (APH) to increase the minimum metal temperature in order to raise the average cold end temperature and to prevent acid dew point corrosion.

Steam air heater or steam coil systems are widely used in industrial furnace systems, incineration systems, crude distillation plants, steam reformers and fired heaters for global oil, gas, and petrochemical industries.

​Basaranlar Proses can supply a steam air heater or steam coil system as a single unit, or more commonly in combination with an air preheater as one package. The SCAP design can be manufactured from a variety of materials, suitable for a wide range of temperature applications.

​COMBUSTION AIR PREHEATER FOR FUEL-FIRED INDUSTRIAL HEATING

For fuel-fired industrial heating, preheating the combustion air flowing to the burners is one of the most efficient and energy-conserving ways to enhance the productivity of your processes. Investing in a customized system designed by Basaranlar, recuperating the heat energy from the exhaust gas stream, not only reduces the CO2 emission and climate change, it reuses available energy in a smart way while saving you fuel consumption and costs.

We supply a wide variety of custom-made air preheaters (APH) for applications to heat the air for furnaces, industrial boilers, steam reformers, box heaters, vertical cylindrical heaters, incineration systems, ammonia and methanol plants, and fired heaters. Depending on your application, we design preheaters manufactured for various media from a range of materials suitable for low temperatures or high temperatures up to 900 – 1000 °C.

Water hammer problem in steam air heat exchanger or steam coil applications:

Water hammer can be caused in a number of ways, including:-

• Failure to remove condensate from the path of high velocity steam in the pipework.
• From an application which is temperature controlled and where condensate has to lift to a return line, or return to a pressurised system.
• The inability of condensate to properly enter or travel along an undersized return line, due to either (a) flooding, or (b) overpressurisation with the throttling effects of flash steam.

Steam locking

The possibility of steam locking can sometimes be a deciding factor in the selection of steam traps. It can occur whenever a steam trap is fitted remotely from the plant being drained. It can become acute when condensate is removed through a syphon or dip pipe.

Diffusers

With steam traps draining to atmosphere from open ended pipes, it is possible to see the discharge of hot condensate. A certain amount of flash steam will also be present relative to the condensate pressure before the trap. This can present a hazard to passers by, but the risks can be minimised by reducing the severity of the discharge. This may be achieved by fitting a simple diffuser  to the end of the pipe  which reduces the ferocity of discharge and sound. Typically, sound levels can be reduced by up to 80%.
