The water tube boiler diagram is shown below, and these two drums are associated via two tubes such as downcomer and riser. At first, the water is supplied into the steam type drum with the help of a water pump. Whenever the fuel is burned, then hot gases will be generated that are permitted to supply in the shell part of the boiler.Get Price
That is right on the edge of using a 1.5" or a 2" pipe. Being conservative, I would go with the 2" exiting the boiler and save a bushing. Then I would reduce to 1.5" or 1.25" just before your air separator, depending on the type and size you are using. The difference in cost between a 2" and 1.5" or 1.25" air separator can be large.Get Price
Water-Tube Boiler (1867) A water-tube boiler is one in which the products of combustion pass around the outside and heat tubes containing the water.

Sep 22, 2021 · Before 2005, older, non-condensing boilers wasted between 30-50% of heat due to combustion gases escaping via the flue. A condensing boiler, in comparison, can be up to 92% efficient. This is because in a condensing boiler, the latent heat flue gases can be repurposed and reused to preheat the cold water coming into the boiler.Get Price

The other type is a water tube steam boiler. It is just the opposite of the fire tube steam boiler; the water is in the inside of the tubes and the hot gases are on the outside of the tubes. In the fire tube boiler, we have a limitation on the combustion chamber diameter and length, and it cannot exceed a certain value. So for large-scale Get Price
Water-tube boilers differ from shell type boilers in that the water is circulated inside the tubes, with the heat source surrounding them. Referring back to the equation for hoop stress (Equation 3.2.1), it is easy to see that because the tube diameter is significantly smaller, much higher pressures can be tolerated for the same stress.Get Price
