May 01, 2011· They were the first to patent their boiler design, which used tubes inside a firebrick-walled structure to generate steam, in 1867, and they formed Babcock & Wilcox Company in New York City in 1891. Their first boilers were quite small, used lump coal, fired by hand, and operated at a very low rate of heat input.
In the counter-rotation unit, the drum rotates against the inward flow of dilute medium. As the medium passes through a slot having a preset depth, magnetite is attracted to the drum. The drum can be adjusted to obtain different medium depths. Losses are typically no more than 0.25 grams/liter of non-magnetic product.

This regulation, by sweeping pulverized fuel from the mill, is very fast; comparable with oil firing response, but needs the coal level to be maintained in the mill. A control circuit monitors the coal level in the mill, and controls the speed of the raw coal feeder to maintain it.
First the coal from the stock yard is sent to mill to pulverize into powder. The pulverized coal is carried into boiler through the pulverized coal pipe by the primary air and a blower is used to blow the heated air. The combustion takes place and a fireball forms due to the tangential firing of coal and fuel oil at four different corners.

Drum level trips are common in the sugar industry. The causes are typically poor operation, poorly configured drum level controls, poorly balanced steam lines or a combination of these and other factors. The JTB philosophy regarding drum level controls on watertube boilers in the sugar industry has changed slightly over the years (Figure 3).
