A team of highly qualified designers, technical drawers and experts for 3D visualisation design boiler systems and plants that always meet our customers’ requirements in every detail.

We ensure high efficiencies over the entire load range and guarantee a long lifetime of our boilers.

Special characteristics of our boiler plants:

• Low operating and service costs
• Optimised combustion with minimized emissions
• Gas tight welded membrane walls
• Stable natural water circulation for steam boiler plants
• Flexible operation regime

An experienced project team engineers individually optimised thermodynamic boiler designs by using own computer programs.

A team of experienced employees realise all projects according to the highest standards. The short communication paths within our company ensure a fluent production sequence.

Main products delivered by our production:

• Boiler in water tube and smoke tube design
• Pushing grate combustion systems
• Heating surfaces using blank or finned tubes
• Pressure vessels and components
• Exhaust gas ducts
• Pipe coil production
• Other welded constructions and special designs

We ensure a smooth process on the construction site and a successful installation of the whole plant. During the commissioning phase, all system components are tested and our client’s employees are made familiar with the plant.

Our service includes:

• Cold checks after finalizing the main installation works
• Function test and part commissioning
• Hot commissioning with checks on the control loops
• Verification of the engineered parameters and final adjustments
• Operation under part load conditions and with quick load changes
• Performance tests
• Training of employees on site

At the end of the project, our clients receive a detailed plant documentation including drawings and descriptions explaining the layout, components and functioning of their new Wulff & Umag boiler system. After the handover of the plant, our after-sales service team provides individual support and helps with any technical questions our clients may have.

Our team designs and manufactures:

• Single-drum water-tube boilers:

  – for high efficiencies and high steam parameters
  – up to 150 t/h, 120 bar, 550 ℃

• Two-drum water-tube boilers:

  – for medium steam parameters
  – up to 100 t/h, 50 bar, 550 ℃

• Waste-heat boilers:

  – for an efficient recovery of waste heat produced by gas turbines, motors or thermal processes
  – 1-50 MWel; 5-100 t/h; up to 120 bar

• Smoke-tube boilers:

  – for gasturbines
  – with cooled or dry combustion chambers
  – 1-15 MWel; 5-60 t/h; up to 40 bar

• Hot water boilers in water-tube design:

  – (with a forced water flow) for high efficiency, duration and flexible operation modes
  – 30-200 MW; 70-250 ℃; up to 40 bar

Our field of expertise includes:

• Direct firing with fuel gases and fuel oils
• Combustion of production residues (especially in the oil and gas industry)
• Special fuels (e.g. refinery or blast furnace gases)
• Dusts and solid fuels
• Heat recovery from gas turbines, motors and thermal processes
