ME Board Problem Local coal with higher heating value of 5,500 kCal/kg is burned in a pulverized coal fired boiler with 25% excess air at the rate of 25.9 M.T. per hour when the steam generated is 220 M.T. per hour. This boiler is served by 2 forced-draft fans of equal capacityGet Price
Gordon notes that adding automatic controls to a steam generator can triple the price. However, the savings in fuel û for people who have low-cost wood or other combustible material - will pay for a SteamGen unit in five years, he says. "SteamGen generators require 100 percent supervision, but operating a boiler is not rocket science," says Get Price
Containers used with systems embodied in paragraphs (d), (e), (g), and (h) of this section, except as provided in paragraphs (e)(3)(iii) and (g)(2)(i) of this section, shall be designed, constructed, and tested in accordance with the Rules for Construction of Unfired Pressure Vessels, section VIII, Division 1, American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code Get Price
supplies inclined water-tubes. The water tubes supply steam back into the top of the drum. Furnaces are located below the tubes and drum Figure 4: Babcock & Wilcox Boiler Yarrow : this type has three drums in a delta formation connected by water tubes. The drums are linked by straight water tubes, allowing easy tube-cleaning.Get Price
The gauge measures pressure of the fluid (liquid and gas) flowing through a pipe or duct, boiler etc. irrespective of prevailing atmospheric pressure. Vacuum (Or Vacuum pressure) (Pvacc) It is the pressure of a fluid, which is always less than atmospheric pressure. Pressure (i.e. vacuum) in a steam condenser is one such example.Get Price
VI BCR* AUTOMATIC "PACKAGED" BOILER This unit is a complete steam or hot water generating system, incorporating a water- cooled vibrating grate as the firing mechanism (Figure 6). Coal is delivered from the storage bin to a hopper from which it …Get Price
24. A coal fired steam boiler uses 3000 kg of coal per hour. Air required for combustion is 15.5 kg per coal at a barometric pressure of 98.2 kPaa. The flue gas has a temperature of 285 °C and an average molecular weight of 30. Assuming an ash loss of 11% and an allowable gas velocity of 7.5 m/s, find the diameter of the chimney.Get Price
A packaged tubular steam boiler often has a steel sheathing in front of the waterwall tubes due to: An internally fired boiler: is less efficient than an externally fired unit A major force that holds the manway doors of boiler drums in place during operation is: boiler pressure.Get Price
- Direct steam-type humidifiers inject boiler-generated steam directly into the air stream. These systems normally operate above 70 degrees C (158 degrees F), and Legionella cannot survive at that temperature. - Atomizing humidifiers use mechanical devices or pneumatic air to create a water mist that evaporates into the air stream.Get Price
A high pressure watertube boiler (also spelled water-tube and water tube) is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which boils water in the steam-generating tubes.In smaller boilers, additional generating tubes are separate in the furnace, while larger utility boilers rely on the water-filled …Get Price

Steam drum internals, a series of screen, scrubber & cans (cyclone separators). Low-water cutoff: It is a mechanical means (usually a float switch) or an electrode with a safety switch that is used to turn off the burner or shut off fuel to the boiler to prevent it from running once the water goes below a certain point.Get Price
Biomass Boiler or Hogged Fuel Boiler Biomass boilers burn bark, saw mill dust, primary clarifier sediment and other solid waste, and other wood-related scrap not usable in product production. Also called "hogged fuel" boilers, biomass boilers make steam and heat for mill use. Bio-sludgeGet Price
The off-gas at a rate of 66,000 Nm3/h leaves the afterburner chamber at a temperature of 1000°C. Heat is recovered in a steam boiler. The gases leave the boiler at 270°C. Steam is generated at 25 atm and superheated to 250°C at a rate of 34 t/h. A steam turbine generates electric power at the rate of 1320 kw/h consuming 22 t/h steam.Get Price
