In the case of industrial process contamination, it is possible for organic contaminants to decompose under boiler temperature and pressure to form organic acids. Sugar is an excellent example of an organic which, when returned in a large quantity, can cause rapid loss of boiler water alkalinity and reduce pH of the boiler water to 4.3 and lower.Get Price
Through this, we can know about the level of water in the boiler. A ball type of safety device is used. Under normal operating conditions, the balls keep the ends open, therefore water or steam can reach the glass tube. If the glass tube is broken, the ball uses the pressure to close the ends. In this way, no water and steam can exit the boiler.Get Price

May 19, 2020 · Steam generators compared to steam boilers, contain less steel in their design and they use a single tube coil instead of boiler tubes and a feedwater pump continuously pumps feedwater through the coil. Steam generators convert water into steam but in a single pass through the water coil transferring the hot gas into the desired output.Get Price
Mar 12, 2013 · The steam generation through these boilers is used to turn the steam turbine and the steam turbine in turn produces the electricity. 6) Heat source – solid / liquid / gas / nuclear / waste gas- If we talk about marine boiler heat source that is being used on ships, then liquid and waste gas come in to the use.
