Measure Guideline: Condensing Boilers - Control Strategies

Condensing boilers achieve high efficiencies because they can recapture the latent energy from the moisture in the combustion gases when those gases condense. For condensing to occur, the boiler's heat exchanger surface temperature must be below the flue gas dew point. If the return water temperature is low enough, it will cool the heat

A typical natural-gas-fired boiler will operate with combustibles concentrations less than 50 parts per million (ppm), while a coal-fired boiler may operate with combustibles concentrations greater than 200 ppm. Generally, combustibles concentrations less than 100 ppm are considered negligible in terms of efficiency impact.

Understanding Steam Pressure Controls: Three Basic

As you drive you regulate the gas pedal to match a speed you desire, and a modulation control for a steam boiler does the exact same thing. The burner will modulate between low and high firing rates depending on the steam pressure inside the boiler and where the modulation control is set.

Troubleshooting a Gas-Fired Hot Water Boiler

Jan 15, 2021 · Understanding the components of a hot water boiler can help with basic troubleshooting. A boiler is a bit more complex than a forced air furnace in that it has more parts, valves, and controls. However, gas-fired boilers are fairly reliable and when problems do occur, they are usually related to the expansion tank or water circulation pump(s).
