How a steam generator works

Used to produce saturated steam in various industrial fields such as cleaning, food industry or chemical industry ... the professional steam generator has a similar operation to a domestic boiler.

Operation of a steam generator

Heating the water causes the creation of steam, which is then distributed through pipes. The water pipes of the steam generator generally serve the function of economizer (ECO), evaporator (EVA) or superheater (SH).

Inside the steam generator there are 3 zones:

  1. The water-steam circuit: water is pushed through the pipes to be heated and transformed into steam
  2. The fuel circuit: where the fuel, before being burned, is brought to the correct pressure and flow rate. Usually, the fuel is methane gas or biogas.
  3. The air-fumes circuit: the air needed for combustion is sent to the combustion chamber.

Types of steam generator

There are various industrial steam generators on the market that differ from each other in various construction and steam delivery characteristics.

  • Type of fuel:



Maintains a sufficient supply of LPG in the cylinders

Requires more maintenance, due to the fumes that tend to dirty the combustion chamber


  • Type of steam delivery:

Instant steam generator

Smoke tube steam generator

Produces steam continuously but of a low type

Produces dry, high-quality steam


The advantages of steam generator

  • Reduction of energy loss, due to the insulation of the body of the professional steam generator.
  • Recovery of heat from the exhaust fumes thanks to the types of advanced systems installed.
  • Low environmental impact, thanks to modern combustion systems.
  • Increased efficiency and reduced energy running costs.
  • Resistant and high performance in the long run.
  • Easy management and maintenance of the plant, not requiring the continuous supervision of experienced personnel.
