  • HIGH FLUE GAS TEMPERATURE - Boiler and Pressure Vessel

    Based on the numbers posted the boiler is less efficient by 2 or 3 percent because the higher flue temperature means less heat is being transferred. The draft over the fire should be checked. Ideally it should be -.01"W.C. The O2 reading is also a little high 4-5% would be more ideal.Learn More

  • EMISSION FACTOR ESTABLISHMENT FOR PALM OIL MILL …

    The stack diameter is 2.4 m for both boilers and the average stack gas velocity is almost the same within each boiler, which are 15.97m/s and 15.94 m/s respectively. The main difference between these two boilers are in terms of average stack gas temperature which are 290 °C for boiler 1 and 224°C for boiler 2, while the average stack gasLearn More

  • Industrial boiler technology for beginners

    On the front of the boiler is an external reversing chamber, which again reverses the flue gases and leads them to the end of the boiler in the 3rd smoke tube pass. Hot water boilers are normally completely filled with water during operation. Steam boilers on the other hand are only 3/4 filled with water; the upper quarter is the steam space.Learn More

  • Boiler Efficiency and Combustion | Spirax Sarco

    The losses are attributable to the temperature of the gases leaving the furnace. Clearly, the hotter the gases in the stack, the less efficient the boiler. The gases may be too hot for one of two reasons: The burner is producing more heat than is required for a specific load on the boilerLearn More

  • How much water is in a one-ton steam boiler? - Quora

    Answer (1 of 2): Standard commercial boilers are sized by their capacity to make steam out of water and measured in the weight of the water/steam processed. The most common dimension used in the English measuring system is pounds per hour. A one ton boiler would be able to make 2,000 lbs of steLearn More

  • New boiler choices. What's the difference? — Heating Help

    Sep 08, 2021 · Getting back to the original question- I'm familiar with the older Smith 8 series boilers (current ones are rebranded Peerless). They're built like tanks. So if that were my house, the first thing I'd try is down-firing the burner slightly. As long as the stack temperature is above 350° F or so, it should run fine without condensing.Learn More
