Industrial chemistry/ IC (Vocational) USO4CICV01/US04CICH02: Chemical Plant Utilities UNIT 6 Introduction A steam generator or a boiler is defined as a closed vessel in which water is converted into steam by burning of fuel in presence of air at desired temperature, pressure and at desired mass flow rate.
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. The Boiler Horsepower (BHP) is. the amount of energy required to produce 34.5 pounds of steam per hour at a pressure and temperature of 0 Psig and 212 o F, with feedwater at 0

Often it is necessary to convert a measure of capacity from one term to another. The conversion table will allow you to quickly convert various measures of capacity. The table and formulas can help you size and pick out components such as condensate pumps and boiler feed pumps. Some additional conversion factors that may prove helpful are shown below.
The gas flow rate is 5 kg/s. Calculate the temperature after compression and the power input. For a steam circuit as shown previously, th e boiler produces superheated steam at 50 bar and 400oC. This is expanded to 3 bar with an isentropic efficiency of 0.9. Total power input = 49.375 + 399.5 = 448.9 kW
TOTAL LOAD = 1,930,090Btu/hr When the light heating load only is imposed, the demand on the boiler is only 14% of its rated capacity. A third, smaller unit should be considered for light load conditions, unless the boiler has a burner with a 10:1 turndown ratio. When multiple boilers are used, care must be taken to assure proper

Designed for pulverized coal, B&W's advanced once-through ultra-supercritical boilers are usually applied to systems with a capacity of 400 MW or more. These clean and efficient boilers usually operate at throttle pressures of 3500 psi (24.1 MPa) or more and steam temperatures in the 1100F (595C) range.

Supposing it is cooled to around 150 °F (and condensed to water), my steam table says about 1100 BTU/lb or 2.5 MJ/kg. 1 kWh = 3.6 MJ, so around 1.5 kg/h of 100 psi steam. The mass requirement would increase considerably if the return line temperature and pressure is closer to the inlet values.
F & A Rating Of Boiler - posted in Student: we need to calculate the boiler capacity based on F&A rating.Our consumption is 2500 kg/hr steam at 17kg/cm2(g)We provide feed water at 100degC to the boiler drum.please suggest, how to arrive at F&A rating.Thanks in Advance.Regards,raghav.
How to Calculate Boiler Heat Input Rate. Depending on its energy source, a boiler may get its heat from the flow of electric current or from burning fuel. Each of these sources offer its own method for calculating the boiler's heat input rate. A separate method, however, works for all boilers. The boiler's
What is a Boiler? Vessel that heats Balancing total energy entering a boiler against the energy that leaves the boiler in different forms -Quantity of steam generated per hour (Q) in kg/hr -Quantity of fuel used per hour (q) in kg/hr -The working pressure (in kg/cm2(g)) and superheat
