Rosink Apparate- und Anlagenbau GmbH
Rosink Apparate-und Anlagenbau GmbH has been developing and producing waste gas heat-exchangers for steam and hot-water boi-
lers in power plants since 1980. The company is a specialist in the manufacture of fully welded helical finned tubes, which are produced
according to the patented NOH process among other techniques. Rosink also produces heating surface cleaning systems that improve
both the efficiency and service lifetime of boilers used in power plants, industrial companies and waste incinerators. Since October 2011,
Rosink Apparate- und Anlagenbau and its approximately 160 employees have been part of the Bilfinger Berger Power Services Group.

Service, maintenance and repair
With a large team of specialists in various fields, we offer our
services to customers around the world. We will support you
in your efforts to determine optimisation potential, to develop
new concepts for modernisation projects and to repair faults.
Regular maintenance work and preventive inspections avoid
unscheduled downtime and guarantee that the facility runs
as it should. An extensive stock of replacement parts ensures
that any component that needs to be replaced can be sourced
quickly. The inspections aim to achieve the highest possible level
of technical availability.
Fabrication
Our fabrication facility is also located at the site in Nordhorn.
On a shop floor measuring over 14,000 sq. m, approximately
160 employees manufacture high-quality, multiply certified
products such as fin tubes, heat exchangers and heating surface
cleaning systems.
Research and development
We are continuously enhancing our products and services.
At present, we are developing a retractable soot blower that
increases cleaning intensity while reducing steam consumption.
For the tailored use of our technology, we are also working on
special thermal flow sensors that will in future allow us to install
our systems without bringing operation to a standstill.

Water cannons
A tried-and-tested cleaning
system for the furnace in
which water is sprayed onto
the opposing wall. Kinetic
energy and the evaporation of
water in surface pores remove
even the most stubborn dirt.
Water-spraying systems
This effi cient cleaning system
for empty passes is based on
a concept similar to the water
cannon. Cleaning intensity is
determined by the volume of
water, nozzle size and sinking
velocity. The patented pendulum
action ensures that every
nook and cranny is cleaned.
Soot blowers
The heating surfaces of horizontal
passes can be cleaned
using traditional soot blowers
or rapping systems. The
blower type used depends on
the degree of fouling.

Rapping systems
Vertical heating surfaces are
usually equipped with rapping
systems. The collectors
are hammered, and these
strikes clean the surfaces. The
system can be provided with
either pneumatic or mechanical
rapping gears.
Shot cleaning
Vertical ECO heating surfaces
can be cleaned not only with
soot blowers, but also with
shot cleaning systems. The
shots are falling through the
heating surfaces removing
the dirt. After being screened
they are led back into the
cleaning cycle.
