  • Why may boiler fuel consumption increase?

    Water in the fuel oil is wasteful because it interferes with combustion. A considerable amount of heat is required to evaporate the water, so more fuel must be burned in order to supply enough fuel for the boiler and enough to evaporate the water in the fuel. 10. Steam leakage. Steam leakage is an obvious cause of high fuel oil consumption. 11.Learn More

  • Precautions and Maintenance Of Boiler on ship - Marine Wheel

    Formation of VOCs in commercial and industrial boilers primarily result from poor or incomplete combustion due to improper burner set-up and adjustment. To control VOC emissions from commercial and industrial boilers, no auxiliary equipment is needed; properly maintaining the burner/boiler package will keep VOC emissions at a minimum.Learn More

  • [PDF] Economizer selection method with reference to its

    The economizers are used for production of steam heating on en route ships. The economizers are producing steam in a heat exchange process from the ship's main engine exhaust gas. Products of the incomplete combustion of the heavy fuel oil remaining in engines, passing the boiler, collect on the heat exchange surface of the economizer. When the incorrect assumptions are made for the boiler Learn More

  • Natural Gas Fired Boilers

    The boiler efficiency is usually reduced to 84-85%, when a coal fired boiler is converted to natural gas. The biggest change is due to the combustion of Hydrogen. This is normally a 4% heat loss while firing coal and about a 11% heat loss while firing natural gas. When firing natural gas, other losses such as dry gas loss, moisture in fuel and Learn More

    Smaller and lighter boilers must have dry chips to ensure complete combustion because it is not possible to adequately dry the chips in relatively small combustion chambers surrounded by water. The result can be incomplete combustion. se to have a smaller infrastructure at the boiler site and to use dry chips. Sometimes, larger chip boilers and less expensive, wetter fuel make better economic sense.Learn More

    cial to optimizing the combustion and boiler efficiency. Excess air will re-sult in higher O2 concentrations and means that you are using valuable energy to heat up excess air. This en-ergy is immediately lost up the stack. Excess fuel will result in too low O2 levels and incomplete combustion. Both literally and figuratively, valuableLearn More

  • What happens if soot accumulates on the economizer

    Jun 26, 2021 · What is soot fire in boiler? Soots are formed from incomplete combustion and use of low grade fuel and high carbon content fuel. At the manoeuvring time, the more incomplete combustion may occur and at that time leaving flue gas velocity is very low, thus unburnt fuel can be adhering on the economizer coils.Learn More

  • 1.1 Bituminous And Subbituminous Coal Combustion

    boilers include the ash from combustion of the fuel as well as unburned carbon resulting from incomplete combustion. In pulverized coal systems, combustion is almost complete; thus, the emitted PM is primarily composed of inorganic ash residues. Coal ash may either settle out in the boiler (bottom ash) or entrained in the flue gas (fly ash).Learn More
