We Design Your Steam Boiler as Requested
Our core business are boilers with steam capacities of about 30 tons per hour. We serve industries from waste disposal to the sugar industry. In addition to our engineering services, we offer you comprehensive services, e.g. maintenance, boiler operator training and much more.
All industries have specific characteristics, e.g. regarding the particular degree of humidity of the steam, the required temperatures, typical condensate return rates and other characteristics. That is why our distinctive knowledge of the industry is of particular advantage.
Steam Boilers from Achenbach
Engineering at Achenbach

A highly specialised engineering team of technicians and engineers concentrates on steam boilers and the associated plant technology: Design, supply and installation, optimisation and maintenance from a single source! The steam boiler specialists at Achenbach know almost everything about the efficient use of steam as a heat transfer medium and about saving energy costs by means of heat recovery.
Heat Recovery Steam Boiler
Excess heat is unavoidable in thermal processes. Depending on the efficiency of the process, the loss of heat can be up to 60 percent. Unused heat generated in industrial processes has a negative impact on the environment.
By using a Waste recovery steam generator, part of the heat is returned to the system and primary energy sources are saved. This sustainable use of energy is not only attractive from an environmental point of view. The use of process and exhaust air heat or hot exhaust gases generated in industrial processes also reduces operating costs. A plant often pays off within just a few months.
Steam Boiler with Burner
The flame-tube boilers from Achenbach are fired with gas or oil if no waste heat is available.
Put simply, water vapour is produced under increased pressure in a steam boiler. This produces temperatures well above the atmospheric boiling point of 100 degrees Celsius. While a conventional pressure cooker usually has an overpressure of around 0.8 bar, which increases the boiling temperature to around 116 degrees Celsius, Achenbach's flame-tube boilers reach an overpressure of up to 30 bar with boiling temperatures of up to 235 degrees Celsius and evaporation of up to 30,000 liters per hour.
Hybrid Steam Boiler (4-Pass)
The 4-pass Hybrid Steam Boiler is the solution if waste heat from an industrial process is to be used in an energy-efficient manner, but the hot waste heat stream is not continuously available in sufficient quantity. If the waste heat fails, the fossil-fired part of the steam boiler automatically takes over the steam supply.
The four-pass hybrid boiler from Achenbach thus combines the advantages of a waste heat steam generator with those of a steam boiler fired by gas or oil. Thanks to its hybrid function, the boiler is constantly at operating temperature. If a cold start is required, the boiler is started with fuel and the exhaust gas flow is switched on at operating temperature.
