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.File Size: 281KB

We also present recommendations for reliable burning of various sub-bituminous coals and their blends in a 575 MW tangentially-fired boiler. For example, we found that firing Indonesian sub-bituminous coals (Adaro and Melawan) considerably reduced NO x (30% reduction) and SO x (reduced to 200 mg/dNm 3 @6%O 2) emissions without post combustion
Oct 23, 2007 · If the Firebox is designed to burn high volitile bituminous coal it will have a provision for pre-heated air entering over the top of the fire to add extra oxygen to the smoke, which burns off a lot of it. But the provision of over the fire pre-heated air is not a common feature in stoves claiming to burn Bituminous coal. It actually is quite rare.

THE ROLE OF COAL CHARACTERISTICS IN BOILER OPERATION by R. R. Leonard, Manager Proposal Engineering Department RILEY STOKER CORPORATION WORCESTER, MASSACHUSETTS Steam generating units for coal firing, and I am thinking both of pulverized coal units and stoker fired units, are designed to accept some range of fuel characteristics.

This unit was originally designed to generate 4,550,000 pounds per hour of main steam flow at 2,650 psig and 10050 F and 4,281,000 pounds per hour reheat steam flow at 602 psig and 10050 F. The original boiler design used eight B&W MPS 89 mills to supply pulverized coal to 56 burners.
bituminous coal after it is fired as follows: “The first thing that the fine fresh coal does is to choke the air spaces existing through the bed of coke, thus shutting off the air supply which is needed to burn the gases produced from the fresh coal. The next thing is a very rapid
Bituminous coals are used routinely by electric utilities and in some industrial applications to fire steam-generating boilers even though their sulfur content can be relatively high. Compared to lignitic and subbituminous coals, the heating value of bituminous coals range between 10,500 and 14,000 Btu/lb.
The boiler efficiency of modern pulverized fuel, hard coal-fired units is 94%–95% (LHV basis), reducing slightly to 90%–91% for lignite-fired units due to the higher moisture content. When combined with the other elements of the Rankine cycle, the overall efficiency currently achievable in conventional plants is in the 40%–45% range.
Bituminous coal fired units show a slight decrease in explosion frequency with increasing number of pulverizers per unit. However, subbituminous fired units show a sharp increase in explosion frequency with increasing number of pulverizers per unit. Pulverizer Age: Without the coal type distinction explosion frequency appears to be independent of
