Saturated steam is generated in a boiler by converting a saturated liquid to a saturated vapor at 200 psia. This is done by transferring heat from the combustion gases, which are at 500°F, to the water in the boiler tubes. Calculate the wasted work potential associated with this heat transfer process.

Heat Recovery Steam Generated (HRSG) technology is a recycling steam generator which uses the heat of exhaust from a gas turbine to generate steam for a steam turbine generating electricity. The simplest scheme of a Combined Cycle Gas Turbine (CCGT) is presented in Figure 1. Figure 1: The simplest scheme of CCGT.

The superheated water is returned to the steam drum which contains dry pipe, baffles, and lance assemblies, where it flashes into 99% dry stream as its exits out to the system. As the water is generated into steam and exits the boiler, the modulating boiler feedwater system controls continuous feedwater flow for constant drum water level control.

A boiler incorporates a firebox or furnace in order to burn the fuel and generate heat. The generated heat is transferred to water to make steam, the process of boiling. This produces saturated steam at a rate which can vary according to the pressure above the boiling water.

The primary purpose of a steam-generating boiler is to make steam to generate electricity. Super-heated steam comes from a boiler to a turbine and turns the turbine blades to create electricity. How water enters and leaves a boiler is called the boiler and steam circulatory system. The pipes and tubes that make up

Generally, a steam boiler is a type of closed container, designed with steel for heating the water to generate steam by some energy source like burning of fuel with eventually. The vapor generated may be delivered at low-pressure for the industrial progression work in sugar industries, cotton mills, and for generating steaming water that can be utilized for heat up fixing at much low-force.

Steam generation in a pulverized coal-fired boiler is accomplished in a configuration of thermal-steam/water sections, which preheat and evaporate water, and superheat and reheat steam. An example of a coal-fired utility boiler is shown in Fig. 4.4 (the fundamentals of steam production and energy flow were discussed in Chapter 4).The major components in the steam generating and heat recovery

Figure 3.22.11 shows all the steam generated by the boiler plant passing through the steam accumulator. This is the more modern generally preferred arrangement. The arrangement shown in Figure 3.22.12 was more commonly used in the past and is still useful when the steam accumulator must be sited some distance from the steam main.
