Bruce / Online engineering & proposals
Choose the application below. Bruce uses your operating conditions to prepare an economizer selection, predicted performance and a proposal for review.

Steam boiler feedwater, hydronic return water and large industrial boiler exhaust lead to different designs. Start with the path that matches your heat sink and boiler.
Select a conventional or two-stage economizer for a commercial or industrial steam boiler. Bruce evaluates the boiler, exhaust, feedwater and operating profile.
Evaluate an external condensing economizer for a new or existing hydronic boiler. Compare a retrofit with a specified condensing boiler, or set a direct performance target.
Begin a selection for a very large industrial boiler where exhaust flow, physical arrangement and service requirements call for an Atlas-class design.
Before you start
The forms can begin with basic boiler data. As you add measured exhaust, water and operating information, the selection better reflects the installation.
Manufacturer, type, capacity and firing conditions. The boiler make helps Bruce consider available gas-side pressure drop.
Water inlet temperature and flow, plus flue-gas temperature at the economizer inlet. Full-load gas temperature is the essential starting point.
Annual hours at each load and your fuel price provide context for expected heat recovery and estimated savings.
