    The recoverable heat corresponding to a stack temperature of 500°F and a natural gas-fired boiler load of 50 MMBtu/hr is read from the table (above) as 4.6 MMBtu/hr. Annual Savings = (4.6 MMBtu/hr x $8.00/MMBtu x 8,400 hr/yr)/0.80 = $386,400 Suggested Actions Determine the stack temperature after the boiler has been tunedLearn More

  • Combustion Testing - Engineering ToolBox

    excessive air leaks in boiler or furnace; wrong fuel-air ratio; Stack Temperature. The "net stack temperature" is the difference between the flue gas inside the chimney and the room temperature outside the burner. Net stack temperatures above 700 o F (370 o C) are in general to high. Typical values are between 330 - 500 o F (160 - 260 o C).Learn More

  • 15 Ways to Increase Boiler Efficiency in Your Facility

    Jul 08, 2021 · 1. Increase Boiler Efficiency: Lower the Stack Temperature. Lowering stack temperatures may be as simple as a day/night set back. This lowers the operating pressure for steam boilers and the operating temperature for hydronic boilers when idling at night or mild days. 2.Learn More

  • Flue-gas stack - Wikipedia

    A flue-gas stack, also known as a smoke stack, chimney stack or simply as a stack, is a type of chimney, a vertical pipe, channel or similar structure through which combustion product gases called flue gases are exhausted to the outside air. Flue gases are produced when coal, oil, natural gas, wood or any other fuel is combusted in an industrial furnace, a power plant's steam-generating boiler Learn More

  • Boiler Economizer: Boost Your Boiler's Performance I RasMech

    Mar 03, 2021 · Lower stack temp and higher duty are better. Keep in mind, every 40 degrees Fahrenheit (4.44 °C) you can lower the stack temperature saves approximately 1% on fuel. Economizers recover thermal energy that would normally be lost in stack exhaust. In order to utilize this wasted heat effectively in an economizer, there must be a fluid that can Learn More

  • Stack temperature question — Heating Help: The Wall

    Raising the operating pressure to 125 psig under the same conditions increases the stack temperature to approximately 453 degrees F, reflecting an efficiency of approximately 83% in the clean, well-tuned boiler. FiRinG RATe if we are looking at stack temperature as one of our primary indicators for determining boiler efficiency, it is imperative to realize the lower the firing rate in a boiler, the lower the stack temperature …Learn More

  • Boiler stack temperature sensor and thermowell, 1k Pt

    May 12, 2006 · The stack temperature is much higher now at 530 degrees. I am just curious if I am going to use more fuel now than before. Does the higher stack temp mean the water in the boiler will heat quicker and reduce burner run time? Or am I going to have increased standby heat loss which will increase fuel usage? What do you think about these numbers? old numbers o2=6.5, co2=10.7, …Learn More

  • Boiler stack temperature sensor and thermowell, 1k Pt

    The Boiler stack temperature sensor and thermowell are designed to monitor the temperature of boiler stacks, steam lines and other applications where the temperature is above the operating range of typical HVAC thermistor type sensors. Maximum operating temperature of 300 Deg C (570 DegF).Learn More

  • Tips for combustion analysis of commercial boilers | 2016

    Feb 17, 2016 · Stack temperature. This temperature is an indication of the heat transfer ability of the boiler. If the stack temperature is too high, the burner is not transferring heat into the boiler. This may be caused by a combination of dirty heating surfaces, over firing, water-side scale buildup, excessive draft or excessive velocity of the water Learn More
