  • Evaluating low-temperature water-heating options

    Oct 27, 2016 · By this time (the late 1940s through the early '50s), Americans decided they no longer wanted to shovel coal into a boiler or furnace; it was much easier to simply adjust a thermostat and burn oil. Many coal-fired cast iron boilers were then retrofitted with oil-fired burners to create this convenience.Learn More

    Tube temperatures should be kept below 560°C in most cases to avoid this type of corrosion. Vanadium-containing fuel oils cause great corrosion, accelerated at above 640°C owing to the fluxing action of molten vanadium complexes. As with coal, additives can be used in the fuel to form higher-melting-point compounds.Learn More

We also give advice on how to set the aquastat controls if heating with a woodstove.Learn More

  • Combustion Air Pre-Heater |

    Heating combustion air can raise boiler efficiency about 1% for every 40F in temperature increase. The most common way to preheat the air is with a heat exchanger on the flue exhaust. The heat exchanger can be either air-to-air or air-to-liquid-to-air. Combustion air pre-heater technology on large coal-fired boilers dates back to the early 1900 Learn More


    Boiler controls help produce hot water or steam in a regulated, efficient, and safe manner. Combustion and operating controls regulate the rate of fuel use to meet the demand. The main operating control monitors hot water temperature or steam pressure and sends a signal to control the firing rate, the rate at which fuel and air enters the burner.Learn More

    air temperature of 400°F. From the table, the boiler combustion efficiency is 78.2% (E1). Tuning the boiler reduces the excess air to 9.5% with a flue gas minus combustion air temperature of 300°F. The boiler combustion efficiency increases to 83.1% (E2). Assuming a fuel cost of $8.00/MMBtu, the annual savings areLearn More

  • 1.1 Bituminous And Subbituminous Coal Combustion

    The most common heat transfer method for coal-fired boilers is the watertube method in which the hot combustion gases contact the outside of the heat transfer tubes, while the boiler water and steam are contained within the tubes. Coal-fired watertube boilers include pulverized coal, cyclone, stoker, fluidized bed, and handfed units.Learn More

    Condensing boilers have a higher seasonal efficiency, typically 84% to 92%, than non-condensing boilers typically 70% to 75%. The seasonal efficiency is an overall efficiency of the boiler over the entire heating season as opposed to the combustion efficiency which is the boiler's efficiency when actively fired, which excludes standing losses.Learn More
