Optimal set-point scheduling in a boiler-turbine

The model has 7 states in the process and 25 in the control system. The optimization strategy uses control vector parameterization in which the boiler controller set-point function generators are modified to produce suboptimum signals. The performance index consists of the total energy input to the system from the fuel and boiler feedpump.

Steam Boiler Types, Construction and Working

Basic Function of a Boiler. As the name states the function of a steam boiler is very simple i.e. generating, storing and distributing the steam. The fluid is contained in the boiler drum called shell and the thermal energy released during combustion of fuel is transferred to water and this converts water into steam at the desired temperature and pressure.

2017-9-22·Steam turbines differ from reciprocating engines, internal combustion engines, and gas turbines in that the fuel is burned in a piece of equipment, the boiler, which is separate from the power generation equipment. The energy is transferred from the boiler to the steam turbine generator by an intermediate medium, typically steam under pressure.

Understanding Steam & Boiler Heating Systems |

2016-1-13·Boiler Systems Operation. In steam heating systems, a boiler furnace heats water by means of a gas or oil-fired burner and turns it into steam. The steam travels through pipes to radiators or convectors, which give off heat and warm the room. As the steam cools, it condenses back into water, and returns to the boiler to be heated again.
