Boiler Tubes are metal tubes located inside of boilers that heat water in order to produce steam. There are two major types of tube boilers: water-tube boilers and fire-tube boilers. In water-tube boilers, water circulates inside the tubes and is heated externally by hot gases generated by the furnace.
U-tube may be attempted, a brief survey is required to obtain a correct understanding of the mechanism of boiling of water in a tube. The change from water to steam is not a simple one. A certain amount of research SINGLE WATER AND Fig. 1. Standard U-tube Boiler has been undertaken in recent years on this problem,
Advantages of Water Tube Boilers: Steam production from 4.5 to 80 t/h. Saturated steam and superheated steam up to 550 C. 95+% efficiency, without additional heat recovery system. 10 – 90 barg typical service pressure. Suitable for indoor or outdoor use.
The aim of this paper is to design and a horizontal fire tube two pass boiler for the commercial cooking of Indian food. The steam generation of this boiler is 300kg per hour. The boiler tank is made of pure mild steel. Mild steel is used to fabricate the fire tubes and other parts such as the furnace, return chamber that make up the boiler.
There are a number of considerations to factor when determining the best boiler for your steam generation needs like operating pressure, steam pounds/hour output, demand fluctuation, general application requirments and total cost of ownership, etc. Two primary boiler types, the firetube boiler and the watertube boiler, are essentially opposite in design.
