What You Need to Know About Residential Steam Boilers

Steam boilers operate like a tea kettle. As water heats to a boil it builds pressure as it reaches the state of steam. Unlike hot water boilers which rely upon a pump to circulate the hot water, steam boilers use this pressure to move the steam through the piping system. The piping system of a steam boiler is usually a one-pipe or two-pipe system.

Solved: A Steam Power Plant Operates On An Ideal Rankine C

A steam power plant operates on an ideal Rankine cycle. The condenser pressure is 20 kPa and the water exits and enters the pump as a saturated liquid. The boiler pressure is 8 MPa and the steam exits and enters the turbine at 700 C.

Answer: Answer: There are different types of composite boilers. Normally one part of the boiler is heated by means of a fuel oil burner and the other part is heated by the exhaust gases from a diesel engine. Heating of one part of a boiler at the time often causes thermal stress that may lead to leakage.
