  • Waste Heat Boiler - an overview | ScienceDirect Topics

    Heat absorbed by water = 0.95 Vs(t 1 − t 2)MJ s −1,. t 1 and t 2 = temperature of hot gases before and after the W.H. boiler, °C.. Total heat as steam = sensible heat in feed water + heat absorbed by water in boiler. In good practice t 2, the temperature at which the flue gases leave the boiler, may be reduced to ca.50 K above the temperature of the water in the boiler.Learn More

    utilized in waste heat boilers, contain high corrosive compounds as well that can condensate on heat exchange surface when cooled down. As for standard cases of fabricated waste heat boilers, ZVU Engineering uses carbon steels, stainless steels, and non-ferrous metals.Learn More

  • Waste heat - Energy Education

    Waste heat recovery systems are more sophisticated than the simple exhaust gas boiler or economizer and the heat can be used in variety of ways. The production of electricity from a turbine can be a means of lowering the number of auxiliary engines.Learn More

  • Chapter 14 Boilers - Pearson

    Fire-tube waste heat boilers have the advantage that they are relatively simple to construct, install and maintain. The heat energy stored in the water can be used to respond to a short-term extra demand, although if all the heat is used there is the disadvantage that it will take a long time to replenish.Learn More

  • Degree of separation of steam impurities in a steam/water

    Moreover, in many cases, a solid alkalizing agent, such as trisodium phosphate or sodium hydroxide, is added to the drum water in order to set the pH value in the boiler. However, if the waste heat boilers are provided with a simple once-through boiler, this purification mechanism is dispensed with, since such a boiler cannot be blown down.Learn More

  • Difference between Simple cycle and Combined Cycle

    Feb 23, 2013 · Sadiya, The same gas turbine can be used in either simple cycle- or combined cycle application. In fact, many applications employ something called a "bypass stack and damper" arrangement on the exhaust of the gas turbine, which can direct the gas turbine's exhaust heat into a waste heat recovery steam generator ("boiler"), or through a stack to the atmosphere.Learn More

  • Method for operating waste heat boiler in flash-smelting

    BACKGROUND OF THE INVENTION. 1. Field of the Invention . The present invention relates to a method for operating a waste heat boiler in copper flash-smelting works, and more particularly to a technique for preventing accretion build-up by reducing the quantity of dust accretion to the water tube laid within the waste heat boiler in the flash-smelting furnace.Learn More

  • How to Destroy a Boiler -- Part 1

    Boilers rely on the water to protect the steel boiler tubes from the temperatures in the furnace which greatly exceed the melting point of the tube material. A buildup of deposits inside the tubes will produce an insulating layer which inhibits the ability of the water to remove the heat from the tube.Learn More
