: : I am working with a small oil refinery in the LA area that is installing a cogeneration system. The local air quality agency will not let us fire the cogen system concurrent with our backup boilers. Therefore, if the cogen system trips offline, we need to start up our Cleaver Brooks watertube backup boiler as quickly as possible to minimize problems in the refinery. Some of our people think it will take 3-4 hours to bring the backup boiler up to speed. Is this realistic? Is there any way to get us up in 15 minutes? I have heard that steam coils in the mud drum will help. Thanks for your thoughts.
:
: Is it possible to run waste heat from your cogen boiler flue gas to your backup boiler furnace? If this were feasible you would be able to keep your backup hot while maintaining the same volume of stack emmisions.
: Don't try and force your boiler on line in 15 minutes or you won't have a boiler anymore. It is also dangerous.
No we can't use the cogen flue gas- it is too far away. Thanks for the idea and your comments on the 15 minutes.
