Boiler Introduction | CleanBoiler.org

As the boiler is 'turned-down' to run at less than capacity, efficiency typically drops. To counter this situation, a modular boiler bank of 3 or more boilers with a programmed controller can improve operational efficiency over a single boiler operating in a turn-down mode, and provides a certain amount of redundancy for back-up.

2020-12-26 · This deposit insulates the superheater surfaces, reducing heat absorption from the flue gas, and reducing the amount of further deposition in the superheater. This insulation is seen by lower superheater steam outlet temperature. The hotter flue gas then deposits material in the next section of the boiler, which is usually the generator bank.

It can be a single bank or multiple banks or tubes either in a horizontal or vertical arrangement that is suspended in the convective or radiation zone of the boiler. The added energy raises the temperature and heat content of the steam above saturation point.

2011-11-28 · Have a look at a feature called over-run. This keeps the pump running when the heat demand is off for a few minutes, presumably to cool down the heat exchanger, and use up the remaining heat. I think the issue is how to keep the zone valves open when the pump is running, because the boiler doesn't know it's safe to run the pump otherwise.
