The inline steam heater is a hot water heater which produces heated water or liquid by blowing steam directly to water or liquid inside piping. This is a highly efficient hot water heater of such system as quite different from conventional heat exchanging system.

Design and features of inline steam heater

Water or liquid inside piping is mixed with steam injected from many tiny orifices provided aslant in the nozzle while passing through the inside of nozzle of an inline steam heater. Thus the water or liquid will get heated and hot water or liquid will get discharged from the outlet.

Applications of inline steam heater

• Instant hot water by direct steam injection: Direct injection steam heaters provide large or small volume of hot water with very accurate temperature settings. They are more energy efficient than indirect systems and heat exchangers.

They provide an unlimited supply of hot water instantly. Both manual and electronic control is possible with this device. Inline steam heater can automatically control heated liquid with the help if an automatic temperature controller.

• Inline steam heaters are used in the steam heat and gas industry heat different gases such as argon, helium, and nitrogen.
• It is also used in industrial buildings for the general heating of water.
• Inline heaters are used in construction industry as these heaters effectively heat steam and gas.
• They are very useful in food processing plants for the heating of slurries.
• Pulp and paper mills industry uses it for the heating of the paper pulp stock streams.

Advantages of inline steam heaters

Equipment space

Inline steam heaters require very less space. The heater fits easily into the existing pipeline which makes the installation easy.

Cost saving installation

The direct injection steam heaters are less costly than heat exchangers and are easier to install and operate. These heaters are offered in varying sizes for heating a percentage or the total flow of boiler make-up water.

Maintenance

Until now, heat exchangers have been sheet metal cans and copper tube, which requires periodical inspection.

However, the inline steam heater requires no periodical inspection because it is not a pressure vessel. There are no concerns of galvanic corrosion with the inline steam heater at all. Inline steam heaters are made with corrosion resistant metals.

Noise generation

Injecting steam into water resembles a silencer but there is absolutely low noise and vibration. When it is desired to operate in a quite environment, sound defending boxes can be used.

Inline water heaters are industries’ best choice when comparing with the efficiency, cost effectiveness, easy installation and easy maintenance.
