BIOFUELS.

Biogenic fuels can be of plant origin or a product of fermentation or digestion of organic material. The chemical and physical properties vary considerably depending on the fuel. Some substances are solid at room temperature, others are liquid or gaseous.

Typical biofuels are:

• Rapeseed oil

• Soybean oil

• Palm oil

• Biodiesel

• Biogas

• Bio natural gas

• Sewage gas

• Gas from biomass gasification

• Wood dust

All of these fuels have a high calorific value of more than 15 MJ/kg (15 MJ/m³) and a neutral CO2 balance when burned. If sewage gas or biogas was previously released uncontrolled, thermal utilization can reduce the impact on the climate even further: these gases contain a lot of climate-damaging methane, which is converted into CO2 during combustion.

Even though the combustion of rapeseed oil, soybean oil, or biodiesel works largely in the same way as the use of light or heavy oil, each individual fuel poses a particular challenge for combustion: All substances differ in terms of calorific value, pour point, viscosity, and ignitability. Because palm oil is solid at room temperature, it must be preheated to a greater or lesser extent, depending on the burner used, in order to be able to convey and atomize it. In addition, most biogenic liquids contain a certain amount of free fatty acids, which are highly corrosive. In this case, all parts that come into contact with the fuel must be made of stainless steel.

IGNITION AND SUPPORT BURNERS.

On rust-fired waste incineration plants and biomass boilers,

as well as on active coating boilers

The SAACKE portfolio includes:

• Robust burners for light oil and natural gas in the power range

between 5 and 60 MW individual burner output for the safe start-up

of waste incineration plants and to ensure the necessary combustion

temperature in waste operation

• Associated fuel lines and control switchgear for this special area of

application

The advantages of SAACKE burners for this area of application are safe,

stable, and low-emission flame formation, homogeneous mixing of all

flue gas streams with the burner flames in all load ranges, and very low

cooling air requirements during standby operation.

WATER TUBE BOILERS.

INCREASED EFFICIENCY AND OPTIMAL EMISSION VALUES.

The SAACKE portfolio includes:

• Burners and combustion systems for standard fuels

(e.g., natural gas or light fuel oil) and special fuels

(e.g., hydrogen, biogas, lean gas, converter gas, or bio-oils,

HVO, molasses, etc.)

• Burners and combustion systems with minimal NOx emissions

• Support and ignition burners for grate-fired or fluidized bed

boilers (e.g., in waste-to-energy plants)

• Modernization of existing boiler systems through the installation

of new burners, new control systems, and/or other modernization

measures.

For water tube boilers, SAACKE supplies both individual burners

and complete fuel valve lines, burner controls, and fully integrated

combustion systems. Whether you are building a new plant or

modernizing an existing one, SAACKE has the right products and

services to make your industrial combustion system future-proof,

energy-efficient, and environmentally friendly. All system elements

used are designed to operate your plant with maximum efficiency

and minimum emissions.

The SAACKE portfolio includes:

Advantages at a glance:

Thermal exhaust air purification is the most widely used method for exhaust

air treatment – and for good reason:

• Maximum reliability in continuous operation

• Low maintenance costs thanks to robust design

• Effective destruction of pollutants through oxidation (e.g., of hydrocarbons)

• Use of the heat energy generated in the production process

• Long-term compliance with legal limits

MODERN LOW-NOX BURNERS FOR ALMOST ANY FUEL

SAACKE’s portfolio includes:

Burners and combustion systems for standard and special fuels,

such as hydrogen, biogas, lean gas, glycerine or animal fat

(e.g. the ROTONOX series)

Burners and combustion systems with minimal emission values

(e.g. TEMINOX)

Customized complete solutionsand various measures for modernizing

and increasing the efficiency of your plant

With their typically large control range and minimal excess air,

SAACKE burners are particularly efficient and highly available.

In plants that are already equipped with SAACKE burners, it is often

not necessary to replace the combustion technology in order to increase

efficiency and reduce emissions. For example, the control and regulation

of a plant can be improved with a seavis control system from SAACKE,

and retrofitting a flue gas recirculation system can optimize your plant

in terms of emissions.

SAACKE also offers measures to increase energy efficiency: Retrofitting

economizers, O2 controls, and air preheaters allows for more efficient

utilization of your plant, while a frequency converter for blowers reduces 

power consumption.

SAACKE GreenDock

ZERO EMISSION ENERGY IN PORT.

Electrify your steam supply – zero fossil fuels & zero emissions during port stays.

SAACKE GreenDock provides local emission free heat supply to your vessel as a

retrofit  solution for all kinds of heating media such as steam, thermal oil and hot

water. The technology used is compatible to boiler and heat generator systems

from all makers and can be provided by SAACKE on a turn-key basis.

ZERO EMISSIONS AT HIGH EFFICIENCY MAKING THE EXISTING FIRED

BOILERS FUEL TYPE IRRELEVANT IN PORT.

SAACKE GreenDock provides clean  energy throughout the whole port stay,

completely emission-free, while operating on shore power instead of fossil

marine fuels. Integrated into the existing system by means of a circulation pump,

the electrical economizer provides the existing auxiliary boiler with clean energy

while the burner remains switched off.

Efficiency and compliance:

Lower emissions and lower OPEX through steam generation from shore power

instead of marine fuels. Resulting  in significantly lower CO2  emission charges

and port fees.

Series design with vessels layout in mind. Low footprint vertical solution and low

height horizontal solution available.

Retrofitting existing systems

Can be retrofitted in any steam, thermal oil and hot water system regardless of

original maker. Installation envoyage or during docking.
