Retrofit packages
When the vessel is sound but the burner or the controls no longer meet the requirement.
| Two common jobs | Low-NOx burner conversion, and control upgrades |
|---|---|
| Usual trigger | An air district rule tightening under sound equipment |
| Quoted against | What is actually installed, not a catalog configuration |
| Hardest constraint | Available gas pressure at the train |
| Often decisive | The outage window the facility can actually give up |
First honest question: is the vessel worth it? A retrofit near end of life is money spent twice.
5 things and we can price it
Get these in the first message and you get a price back, not a list of questions.
- 01 Boiler and burner Nameplates for both, plus photos of the front and the gas train.
- 02 The requirement District, rule, target NOx, and compliance date.
- 03 Utilities Gas pressure at the train, electrical service, and stack arrangement.
- 04 Room Clearances in front of and around the boiler.
- 05 Window Available outage dates and duration.
The short version
Two retrofits come up repeatedly in this state. The first is a low-NOx burner conversion driven by an air district rule tightening under equipment that is otherwise fine. The second is a control upgrade on a boiler whose original system is obsolete or whose owner now wants trim, sequencing, or BAS visibility.
Both are quoted against what is actually installed rather than a catalog configuration, which is why a retrofit quote asks more questions than a new-equipment quote does.
What makes it the right part
- Is the vessel worth it?
- The first honest question. A retrofit on a boiler near the end of its life is money spent twice, and we would rather say so than quote it.
- The rule that triggered it
- Which district rule applies and by what date. It sets the target and often the schedule.
- What has to stay
- Existing footprint, gas train, stack, and electrical service all constrain the answer, and available gas pressure constrains it most.
- Outage window
- What downtime the facility can actually give up frequently decides the approach more than the technical options do.
The rest of the room
- Burner & Combustion The parts that stop a burner from lighting, and the ones that stop it from staying lit.
- Trim & Safety The devices an inspector looks at first, and the ones with the least room for improvisation.
- Feedwater & Condensate Pumps, seals, and the level controls that decide whether the boiler ever sees water.
- Controls & Instruments Replacement controls and the sensors that feed them, usually on equipment nobody has the manual for.
- Gaskets & Consumables The cheap items that turn a one-day job into a three-day job when they are not on the truck.
