Stainless steel tube shields
and at critical gas paths in both modules |
|
| · |
Increased the steam output of a 1974
waste heat boiler from 121,000 pph to 200,000 pph to accommodate
higher gas flows. |
| · |
Increased the steam output of a 1972
industrial package boiler from 150,000 pph to 210,000 pph to accommodate
new operating requirements. |
| · |
Investigated and solved
the problem of furnace tube failures in a 1974 2-drum boiler
caused by operating conditions. |
| · |
Converted a pulverized coal fired
1977 boiler to a turbine exhaust gas heat recovery boiler. |
| · |
Converted a fresh air fired 1999
heat recover boiler to allow operation with turbine gas exhaust. |
| · |
Rebuilt and redesigned four (4) competitor's
1980 refused derived fuel (RDF) boilers by adding furnace height
and our Travagrate®
Stoker to each boiler to
meet new operating conditions. |
| · |
Designed a 1985 waste heat boiler's
superheater by upgrading the tube material and expansion system
due to higher operating conditions of a fluidized bed combustor. |
| · |
Designed steam drum purifiers to
obtain 1 ppm steam purity and installed anti-vibration flue
gas baffles on a 1970 waste heat boiler to accommodate a 50%
increase in the flue gas flow rate. |
| · |
Factory rebuilt several 1960 &
1970 industrial package boilers salvaging only the steam and mud
drums and updating design features to current standards. |
| · |
Improved boiler start-up ramp rate
of an auxiliary 1967 industrial package boiler from several hours to minutes. |
| · |
Increased a 1989 industrial package boiler's
gas side casing and design to accommodate new higher gas side
operating conditions. |
| · |
Replaced a Lunstrom air preheater
with a fintube economizer to help improve boiler efficiency
on two (2) 1968 and 1979 industrial package boilers. |
| · |
Redesigned the superheater on two
(2) - 1979 industrial package boilers by providing a steam cooled
tube support system to match new cyclic operations and accommodate
field installation. We also provided all the inner and outer
casing upgraded to current designs. |
| · |
Upgraded a 1970 industrial package boiler's
rear wall tubes for greater thermal expansion and provided a
lower drum steam heating coil to keep the boiler on hot stand-by. |
| · |
Obtained 60% NOx reduction without
FGR by changing out a dual burner installation to a single burner
application on a 1967 industrial package boilers. |
| · |
Installed FGR on two (2) existing
1972 industrial package boilers and obtained 70% NOx reduction
with our Indeck Keystone Energy burner. |
| · |
