Boiler Calculations - energy.kth.se

2003-10-30 · Specific enthalpy of saturated water and steam (in the steam drum) can be read from an h-s diagram or steam tables, as the pressure in the steam drum is known. In once-through boilers the determination of specific enthalpy after the evaporator is based on the temperature. The reason for this is the unclear state of supercritical steam after the

The Role of Coal Characteristics in Boiler Operation

2018-2-1 · that output of the steam generator may be reduced. In short, lower Btu coal will increase the pounds of coal to be handled and when the variations are large enough we can expect a reduction in boiler capacity. Higher Btu coal seldom gives any pro- blems in boiler operation or performance. See Figure 1 for typical heating values of various coals

Boiler (power generation) - Wikipedia

2019-7-20 · The source of heat for a boiler is combustion of any of several fuels, such as wood, coal, oil, or natural gas. Nuclear fission is also used as a heat source for generating steam. Heat recovery steam generators (HRSGs) use the heat rejected from other processes such as gas turbines.. Solid fuel firing. In order to create optimum burning characteristics of the fire, air needs to be supplied

Heating Efficiency EGEE 102: Energy Conservation …

2019-8-9 · Not all the energy from the fuel is released, and not all the heat is available to heat the place. For example, if a furnace's efficiency is, say, 50 percent, then twice as much fuel would be needed to heat a home. Looking again at the table on the previous screen, we saw that the heating value of fuel oil is given as 140,000 BTUs.
