Tha design pressure Is 1400 psL Having pioneered Cyclone Furnace firing for industrial steam plants, a large chemical manufacturer has recently placed its fourth and fifth Cyclone-fired boilers into opet-. ation. The Am pressurised Cyclone-fired boiler ever built has been in successful continuous operation at one of dtk company's plants since February 1949. ELIMINATION OF FLY ASH PROBLEM Low fly-ash dischatge to the stack, without the use of p ripitacors, was a prime consideration in the original srito tion of- Cyclone Furnaces for the first three units back to 1946. Most of the coal-ash is converted to liquid slag wjj is removed through the slag tank, ond con be disposed * readily. Thus, some of the most difficult problems in po*m plant operation -- preventing heavy stack discharge M", eliminating the handling of large amounts of useless ty ash--are overcome. But, in addition to solving these lems, a whole host of other benefits have also been tw1 k^Sfld Cyclone Furnaces were thus the logical choice ktbe firm's two-new units. BONIFICATION OF COAL BURNING EQUIPMENT nplifiation of the entire process of supplying and burncoal is an importont asset of Cyclone Furnace firing. Induces maintenance costs, makes operation easier, and availability. This is because pulverizers, with fcbdrives, fans, ducts, and burners are oot needed, since ktydooe Furnace uses coal which is merely crushed, in- of.pulverized. This olio increases safety and lends lf ftadily to "push-button" operation. OKEATER FUEL EFFICIENCY -- WIDE COAL RANGE firing efficiency results from the great turbulence Tttyb temperatures in the Cyclone Furnace. Carbon loss practically eliminated. In addition, excess combustion . ? reduced, bringing o corresponding reduction in heat the stack. A wide range of coals is burned* in the Cyclones. Piney Fork coal is the designed fuel for this plant, but'coals of. many different varieties have been burned successfully. PRESSURE-FIRING -- NO INDUCED DRAFT PAN Pressure-firing without induced draft fans is another pioneering achievement of this chemical company in its five Cyclone-fired units. Since the first boiler was placed on the line nearly five years ago, pressure-firing has contributed to smoother operation with reduction in fuel consumption. Having only forced draft fans on the unit eases the oper ator's tasks, simplifies controls, and saves considerable auxiliary power. * B&W's experience with Cyclone Furnaces, Pressure Firing, and so many other cost-saving engineering advances, is at your disposal when your oext plant is being designed.
