A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam generator.. A boiler or steam generator is used wherever a …

Price : Get Quote Capacity : 22.5 Kg per coil A coil type boiler is water tube design, the water travels through the coil and is surrounded with flue gases. The steam generated is directly fed to the process.

The steam generating boiler has to produce steam at the high purity, pressure and temperature required for the steam turbine that drives the electrical generator. Geothermal plants do not need boilers because they use naturally occurring steam sources. Heat exchangers may be used where the geothermal steam is very corrosive or contains excessive suspended solids. A fossil fuel steam …

· PDF fileBoiler is a steam producing equipment, which produce steam with burning of fuel. Mostly coal is used as fuel in boiler. Efficiency of the boiler should be determined by two method, direct method and indirect method. It required miscellaneous parameters for determining the efficiency. These specification are chemical analysis result of coal, feed waters analysis, coal feeding rate, steam pressure, steam …
