DIRECT STEAM INJECTION HEATING
Liquids can be heated by direct contact with steam either in pipelines (inline) or inside vessels (intank). Heating is extremely efficient and virtually silent. 
Applied Vacuum supplies equipment and solutions for both pipeline and tank heating of liquids by steam injection.

INLINE STEAM HEATING
Inline steam injection heating is used to heat liquids flowing in a pipe, for example the liquid at the inlet of the heater is 55C and at the outlet will be 75C, this is achieved by direct injection of steam through a carefully designed bucket diffuser where steam is injected through multiple small (2-10mm) holes. The bucket diffuser is necessary to avoid steam hammer within the pipeline. 
Applications of inline heaters include:

• White water heaters for the pulp and paper industry
• Acid stream heating in metallurgical plants
• Maize and starch cookers
• Process water heating

INTANK STEAM HEATING
Intank heaters are fitted inside vessels and steam is introduced directly into the heater. The hot discharge fluid from the heater serves to circulate and mix the contents of the tank.

We supply intank heaters for the following applications:

• Water heating
• Reactor pre-heating
• Process liquids heating

 ADVANTAGES OF VENTURI STREAM HEATERS

• Can be fabricated in any materials of construction
• Resistant to highly corrosive fluids
• No moving parts
• Available in all sizes
• Intank Venturi Heaters can utilize existing steam capacity
