Specifications: Are available in sizes far greater than a fire- tube design , up to several million pounds- per-hour
Hand Boiler. As a result it shoots up the glass tube and settles in the top bulb, since it cannot go any further. Next, the vapor bubbles (created by the evaporation process) travel up through the glass tube from the bottom bulb and into the liquid in the top bulb. These vapor bubbles force themselves through the liquid and cause it to bubble,
D type water tube boiler. In the water tube boiler, the water and steam flow inside the tubes and the hot gases flow over the outside surfaces. Where as in fire tube boilers hot gases from combustion travels through the tubes. flue gases produced from furnace where fuel is burnt. Water tube boiler design and working.
