Water Tube Boiler Efficiency Calculation

Water Tube Boiler Efficiency Calculation Related Information

1. ENERGY PERFORMANCE ASSESSMENT OF BOILERS

It is calculated by dividing the boiler output (in BTUs) by the boiler input (in BTUs) and multiplying by 100. The actual input and output of the boiler are determined though instrumentation and the data is used in calculations that result in the fuel-to-steam efficiency. Heat Loss Method.

efficiency of boiler – Water Tube Boiler

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 …

Water boils under constant temperature and pressure, so a horizontal line inside the enclosed region represents a vaporization process in the T-s diagram. The steam/water heating process in the boiler represented by the diagram in figure 2 can also be drawn in a T-s diagram (figure 4), if the boiler pressure is assumed to be e.g. 10 MPa.
