Why steam boilers short-cycle - Heating He

Every steam system is wide open to the atmosphere. Before each cycle, all the pipes and radiators are completely filled with air because the air vents are wide open. Those vents work in both directions – out and in. The boiler fires and steam forms. It races out of the boiler, shoving the air ahead of itself and toward those air vents.

The boiler is oversized. You're supposed to size the boiler and fire the burner to the connected piping-and-radiation load. In the boiler manufacturer's literature, they call this load the D.O.E. Heating Capacity. If your boiler is too big, its ability to produce steam will exceed the system's ability to condense steam. The burner will short-cycle.

The boilers used on the Minnesota State University, Mankato, campus are stack drum boilers, in which the drums are stacked one above the other. Also called D type water tube boilers, they are the most common type of small- to medium-sized boilers. The upper drum, called a steam drum, is where saturated steam leaves the boiler.

2.3 Boiler and steam cycle model. In the steam cycle shown in Figure 1, the pressure of the feed water increases to 2 atm by Pump 1. The feed water entering the deaerator is further preheated to 127 °C by the steam at 159 °C and 6 atm coming from the turbine extraction valve. The pressure of the preheated feed water rises to 67 atm by Pump 2.

Rankine cycle - Wikiped

The Rankine cycle is a model used to predict the performance of steam turbine systems. It was also used to study the performance of reciprocating steam engines. The Rankine cycle is an idealized thermodynamic cycle of a heat engine that converts heat into mechanical work while undergoing phase change. It is an idealized cycle in which friction losses in each of the four components are neglected.

Steam is the working substance used for the propulsion of many surface ships, including nuclear and conventionally powered steam ships. Central to understanding the operation of steam propulsion is the basic steam cycle, a process in which we generate steam in a boiler, expand the steam through a turbine to extract work, condense the steam into water, and finally feed the water back to the boiler.
