This was a unique project in
that the original coal boilers vented through an extremely large
chimney that caused excessive cooling and condensation with the
current natural gas configuration. CRS engineered and installed
a combination of Olympic flexible and rigid sectional stainless
steel linings to improve efficiency and reduce condensation.
PUBLIC SCHOOLS (ONGOING)
The DC Public School
System is undergoing an extensive renovation of their school boilers
and chimney stacks. In 2003 and 2004, this firm installed boiler
chimney stacks for twelve public schools with chimneys ranging from
approximately sixty to one hundred and forty feet in height. Most
required installation of one or more flues using chimney breaching
material manufactured by Selkirk-Metalbestos.In some cases, interior
firebrick was removed prior to installing the linings.
HAVEN COUNTRY CLUB
During a complete renovation
project, eight new fireplaces were constructed in various
locations throughout the building. In most instances, there was no direct access through the
structure to the roof. Each
chimney was required to terminate at pre-designed chimney
locations. CRS engineered and installed double-wall Selkirk
Metalbestos Class-A chimneys in a variety of sizes and complicated
configurations to allow termination at the designated locations
while maintaining required clearance to combustibles within the
This was a one hundred
and twenty-five foot masonry chimney with firebrick lining.
The brick had become dislodged from the outer courses of
masonry and threatened to collapse.
Boiler exhaust infiltrated behind the firebrick course causing
the exposed walls of the chimney within the building to become extremely
hot to the touch. Sixteen
thousand firebricks were removed and a new Metal-Fab brand stainless
steel pressure stack lining was installed.
GEOGRAPHIC WORLD HEADQUARTERS
was another Washington, DC project in which a one hundred and
twenty foot chimney was lined for the newly installed boilers
using Selkirk Metalbestos stainless steel stack materials.
Towers is a thirteen story residential apartment complex located
on Columbia Pike in Arlington, Virginia.
During the course of renovating the building, new boilers
were to be installed along with lining of the masonry chimneys.
The interior size of the chimney was insufficient to install
the required boiler stack.
Therefore, 24,000 interior firebricks were removed prior
to installing a Selkirk-Metalbestos #316 alloy stainless steel pressure
project similar to the one above was completed in an adjacent
building in 2004 using the same methods and type of chimney lining
project for this same owner has been contracted and is scheduled
for the summer of 2006.
An oversized hundred
and forty foot chimney and lack of access at the base prevented
installation of a standard single-wall venting system for this installation.
CRS engineered a double-wall stainless chimney system to serve two
new boilers. The bottom portion was installed adjacent the original
masonry chimney and penetrated to the interior at a point thirty
feet from the base.
WASHINGTON UNIVERSITY STUDENT APARTMENT HOUSING
The interior of the boiler stack in
this eight story apartment building was in extremely poor condition as
a result of having been used previously to vent a coal-fired
appliance. CRS renovated the interior and installed a Selkirk
stainless steel vertical stack to isolate the flue gases and prevent
further deterioration of the masonry.
