Aug 01, 2012 · Boiler Types: Packaged fire tube units up thru 6900 kW (700 boiler horsepower) are acceptable. Packaged water tube units are acceptable for any capacity requirement. The choice between water tube and fire tube units must be based on life cycle costs, and available space in the boiler room.Learn More
capacity, arrangement, and standby capability of the boilers and auxiliary equipment used to generate heating hot water for heating and environments control. It applies to the design of new hot water boiler (boiler), hot water boiler replacement, and modification of existing hot water boiler(s), in all climates.Learn More
Mar 10, 2021 · This has driven the market standard to pumps with variable speed drives and high efficiency condensing boilers. These condensing boilers can be divided into two subcategories based on the volume of water they can hold and leads installers to consider choosing high mass fire-tube boilers versus low mass water-tube boilers.Learn More
Try cocks are used to determine the boiler water level if the gauge glass is not functional. 2-All steam boilers must have two methods of determining the water level in the boiler. The gauge glass is the first and easiest method for determining boiler water level. A second method for determining boiler water level is try cocks. Try cocksLearn More
1. Water tube high pressure steam boilers capacity upto 130 tph for process industry and also for power co-generation pressure up to 105 kg/cm2 and superheater temperature upto 540°C based on multi fuel bagasse, husk, agrowaste, palm seeds, coal on furnace grates like chain grate stocker, dumping/pulsating grate, FBC/AFBC etc.Learn More
capacity. c. Use tubes that have extended surface on the flue gas side. Heat transfer from the tube to water is easy, but hard for flue gas to the tube. For a Firetube boiler, this means notches in the inside of the tube. In a Watertube, this could mean adding fins to the outside of tubes.Learn More
Can you plz elaborate the question. You just want to either see the Water tube boiler image or it's working. There are basic two types of Boiler 1. Fire tube Boiler 2. Water tube Boiler Fire tube boiler- In this Boiler Flue gases flow inside the TLearn More
These design changes have resulted in a marked improvement in heat transfer efficiency of the fire-tube boilers. Another outcome from this is that the overall footprint (boiler size) of the fire-tube boilers will be smaller in comparison to the water-tube boilers only in the lower capacities up to about 4,000,000 BTU/hr.Learn More

Since the amount of steam delivered varies with temperature and pressure, a common expression of the boiler capacity is the heat transferred over time expressed as British Thermal Units per hour. A boilers capacity is usually expressed as kBtu/hour (1000 Btu/hour) and can be calculated as. W = (hg - hf) m (1) where. W = boiler capacity (Btu/h, kW)Learn More
S = 105 – 80. P2. Cut-in Pressure Delta. S = 25. Factor of Evaporation. Water enters the boiler at 225°F. The boiler pressure is 100 psi and the boiler water temperature is 338°F. The latent heat is 881 Btu.Learn More
Feb 24, 2012 · A water tube boiler is such kind of boiler where the water is heated inside tubes and the hot gasses surround them. This is the basic definition of water tube boiler. Actually this boiler is just opposite of fire tube boiler where hot gasses are passed through tubes which are surrounded by water.. Advantages of Water Tube Boiler. There are many advantages of water tube boiler due to which Learn More

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 …Learn More
A boilers capacity is usually expressed as kBtu/hour (1000 Btu/hour) and can be calculated as. W = (h g - h f) m (1) where . W = boiler capacity (Btu/h, kW) h g = enthalpy steam (Btu/lb, kJ/kg) h f = enthalpy condensate (Btu/lb, kJ/kg) m = steam evaporated (lb/h, kg/s) Boiler Horsepower - BHP.
