Sizing calculations of Boiler Pumps and ID /FD Fans : Sample sizing calculations for BFW pumps and Fans for a typical Coal fired Boiler generating steam of 50,000 Kg/hr at 67 kg/cm2 and 485 degC. (110,000 lb/hr at 950 PSI & 905 F). Feed Water inlet at 105 C and Exhaust gas temp at 150 [...]
Sample Combustion Calculations by weight method Combustion calculations are starting point for Boiler or any Thermal equipment design. Here is a sample calculation done for Coal with calorific value of approximately 7200 Kcal/kg (12960 BTU/Lb). Coal composition in % is as follows:
Boiler Efficiency calculations Efficiency is a very important criterion in Boiler selection and Design. Efficiency figure depends upon the type of boiler as well as on the type of fuel and it's constituents. For example, efficiency of a Bagasse fired boiler is about 70% where as that of oil fired boilers is about 85 %. [...]
Boiler Heat Duty Calculations: Convert actual steam rating into From and At 100 C Steam capacity from and at 100 C (212 F) is equivalent steam capacity if operating conditions are reduced to atmospheric pressure
