Combustion systems, boilers and heat exchangers

Since 1901 we have been developing solutions for more efficient energy use – with experience, technical know-how and a clear view of the future.

01Heat exchangers

Wasted heat? We make more of it.

Why leave valuable energy unused? Our heat exchangers recover the heat that would otherwise be lost with the flue gas – and make it usable again.

What this means for you:

  • Lower energy losses
  • Higher efficiency
  • More economical plant operation

Since 1901 we have combined experience with intelligent heat engineering, developing solutions that work reliably – especially when it matters in day-to-day operation.

Your benefitUse more energy. Lose less. Work more efficiently in the long term.

02Combustion

Technology that adapts to your fuel.

No two fuels are alike. Moisture, quality and composition can change – yet your plant still has to run reliably.

That is why we develop combustion systems that match your fuel and your requirements precisely. For stable combustion, efficient operation and the lowest possible emissions.

Your benefitA combustion system that thinks ahead and fits your plant – not the other way round.

03Biomass power plants

What is left over becomes valuable energy.

What is a residue today can supply valuable energy tomorrow. We make biomass usable and develop complete plants that generate heat and electricity from regionally available fuels.

We accompany our customers from the first idea to the operating power plant.

From fuel handling through combustion and boiler to flue gas cleaning, we match every component to the others.

One contact. One overall concept. One plant that works.

Your benefitFewer interfaces, clear responsibilities and a solution from a single source.

04Steam boilers

When heat becomes performance.

A good boiler has to do more than just produce steam. It has to work reliably, use energy efficiently and fit perfectly into the plant as a whole.

That is why we do not develop our boiler solutions in isolation, but as part of an overall system.

The result is a plant that uses its energy as efficiently as possible – day after day.

Your benefitReliable performance, efficient use of energy and a system tailored to your requirements.

05Flue gas cleaning

Emission control starts at the design stage.

A modern energy plant should not only operate economically. It should also take responsibility for people and the environment.

Our flue gas cleaning solutions reduce emissions and are designed so that your plant complies with the limits that apply to it.

In doing so, we combine emission reduction with economical plant operation.

Your benefitCoordinated cleaning stages, design to the applicable limits and a plant that can be operated economically.

06Complete plant engineering

Many components. One well-thought-out solution.

An energy project consists of many individual tasks. Even so, for you it should not feel like a hundred different projects.

Kablitz combines planning, engineering, combustion, boiler, heat recovery and flue gas cleaning into one consistent overall concept.

From the first idea to the finished plant, you have an experienced partner at your side.

Your benefitFewer interfaces, clear processes and a solution in which all components work together.

07Service

So that your plant keeps running reliably.

Our work does not end with commissioning. Because we know that a plant is only successful if it still runs reliably after many years.

That is why we support our customers in the long term – with maintenance, spare parts, optimisation and personal technical advice.

When requirements change, we develop the right solution together.

We are there when it matters.

Your benefitShort distances, fast support and a partner who knows your plant in the long term.

Technologies & products

Our products in detail

Stepped grate surface of the Kablitz type 415 reciprocating grate

Air-cooled grates

Modular grate systems for the combustion of biomass and other solid fuels. Hydraulic drives and adjustable undergrate air zones allow adaptation to the fuel in question.

Questions about choosing plant technology

How is a combustion system selected?

Selection depends on the fuel and plant requirements. Kablitz offers air- and water-cooled grate systems and pulverised fuel firing. Fuel analysis and design data provide the basis for project-specific selection.

Fuels and requirements

Which stages make up a complete plant?

The process runs from fuel handling through combustion and boilers to flue gas treatment. Boiler technology is matched to the required form of energy, such as process steam, hot water or thermal oil.

Complete plant process

What does the process control system connect?

The process control system connects data acquisition, combustion control and plant visualisation. Interfaces to other plant systems, redundancy and remote maintenance are defined for each project.

PLC/SCADA and interfaces

SPS / SCADA

Bringing the technology together.

From data acquisition to the operator interface: the process control system connects combustion, boiler and the interfaces of other trades.
