Steam generators for industrial process and energy applications

powerful, safe and efficient

Steam boiler systems and indirect steam generators have always been the central components of many industrial energy and process heating systems. They typically generate saturated steam as an energy source for heating, driving, drying or for chemical, process engineering and thermal processes. CAW develops and implements robust steam generator systems for continuous industrial operation – designed for high availability, safe operation and efficient energy conversion.

Our steam generators are individually adapted to the respective process requirements and can be flexibly integrated into existing systems or used as part of new energy and heating concepts.

How does a steam generator work?

A steam generator, essentially a fire-tube boiler with a thermal oil heating bundle installed at the bottom, produces dry saturated steam by heating and evaporating the previously treated feed water – which has been filtered and usually softened and then thermally degassed – using thermal oil as a heat source. The steam produced in this process is then available as an energy source for various industrial applications. These devices operate fully automatically in a pressure range of up to approx. 30 bar and can be operated without a traditional, permanently present boiler attendant.

Structure and process steps

Heat source: The required heat is provided by indirect heating using thermal oil.
Heating surfaces: The heat is transferred via immersion heating surfaces to the preheated feed water until the desired steam pressure and thus the required steam temperature are reached.
Steam chamber: The steam generated collects above the boiling feed water level and is discharged from the housing in a controlled manner.
Feed water system: Raw water is filtered, softened, treated using thermal trickle degassers, preheated in a storage tank and continuously fed to the steam generator by means of feed pumps.
Control and safety devices: Monitoring of pressure/temperature, water level and control/regulating valve.

Where are steam generators used?

Steam generators are used in a wide range of industrial plants where steam is required as an energy, drive or process medium. CAW implements both stand-alone steam systems and systems in combination with other heat generators.

Typical system types and operating environments

Indirectly thermally oil-fired steam generators

Generation of dry saturated and superheated steam using thermal oil.

Energy plants

Use of steam for combined heat and power or electricity generation.

Combined heating systems

Integration into combustion, thermal oil or waste heat utilisation concepts.

Use as part of complex plant concepts

In conjunction with thermal oil heaters for indirect steam generation.
As waste heat steam generators – and thus as classic steam boilers – as downstream systems in incineration plants or waste-to-energy plants.
In combination with ORC systems for increased efficiency.
As a central steam source for several production areas.

Industries in which steam generators are used

Steam generators are indispensable in many branches of industry, as steam is a virtually universal energy source. CAW systems are used across a wide range of industries.
