Steam Calculators: Boiler Calculator
Steam, Boiler, and Blowdown Pressure are the same. Combustion Efficiency is the % of fuel energy that is directly added to the feedwater and not otherwise lost or used. Blowdown Rate is the % of incoming feedwater mass flow rate that leaves the boiler as a saturated liquid at boiler pressure.

heat to the water in the boiler. A 4-pass design provides four opportunities for heat transfer. The stack temperature of a 4-pass boiler will be lower than the stack temperature of a 2 or 3-pass boiler, of the same basic design, operating under similar conditions. Because of this fact, the 4-pass will have higher efficiency and lower fuel cost.

Vacuum steam is the general term used for saturated steam at temperatures below 100°C. Example - Boiling Water at 100 o C, 0 bar Atmospheric Pressure. At atmospheric pressure (0 bar g, absolute 1 bar ) water boils at 100 o C and 417.51 kJ of energy is required to heat 1 kg of water from 0 o C to evaporating temperature 100 o C.

The primary purpose of the boiler is to supply energy to the facility's operations – for comfort heating, manufacturing process, laundry, kitchen, etc. The nature of the facility's operation will dictate whether a steam or hot water boiler should be used. Hot water is commonly used in heating applications, with the boiler supplying water to the system at 120°F to 220°F.

Steam Superheaters in Industrial Boilers. The Steam Superheater is a coil type heat exchanger which is used to produce superheated steam or to convert the wet steam to dry steam, generated by a boiler.. It is different from a boiler in a way that, boiler utilizes both sensible heat as well as latent heat to convert water into steam while superheater utilizes only sensible heat to superheat the

Nov 21, 2016 · With thermal fluid heaters, the efficiency is known to be higher than with conventional steam systems.Flash losses in a typical steam system can be 6% to 14%. Add to that blowdown losses up to 3% and de-aerator losses of 2%. Clearly, the difference in the efficiency of the two systems is pronounced as thermal fluid systems do not suffer any of these losses and can operate up to 30% …
