Steam Power Cycle and Basics of Boiler 1. THERMAL POWER PLANT by: Mulugeta T. 1 2. CHAPTER-2: 2. Analysis of Steam Cycles 2.1 Introduction • A steam power plant continuously converts the energy stored fossil fuels (coal, petroleum, and natural gas ) or fissile fuels (uranium, thorium) OR other energy resources in to shaft work and ultimately into electricity.
The boiler puts 25 kW of heat into the cycle and produces wet steam at 300oC. The condenser produces wet steam at 50oC. Calculate the following. i. The efficiency of the plant. (43.6%) ii. The net power output. (10.9 kW) iii. The heat removed by the condenser. (14 kW) 2. A steam power plant is based on the Carnot cycle. The boiler is supplied with
Superheated steam at 40 bar absolute and 500°C flows at a rate of 250 kg/mm to an adiabatic turbine, where it expands to 5bar. The turbine develops 1500kW. From the turbine the steam flows to a heater, where it is reheated isobarically to its initial temperature. Neglect kinetic energy changes.
Power Systems for the 21st Century - "H" Gas Turbine Combined-Cycles ceed to a downstream boiler or heat recovery steam generator (HRSG). The resulting steam is passed through a steam turbine and the steam turbine output then augments that from the gas turbine. The output and efficiency of the steam "H" Gas Turbine Combined-Cycles
with a steam turbine and generator and the process steam is obtained in two ways as follows. • By exhausting the steam at the required pressure (typically 2 bar) to the process instead of to the condenser. A turbine designed to do this is called a BACK-PRESSURE TURBINE. • By bleeding steam from an intermediate stage in the expansion process.
A combined system containing solid oxide fuel cell-gas turbine power plant, Rankine steam cycle and ammonia-water absorption refrigeration system is introduced and analyzed. In this process, power, heat and cooling are produced. Energy and exergy analyses along with the economic factors are used to distinguish optimum operating point of the system.

Steam, Boiler, and Blowdown Pressure are the same. Combustion Efficiency is the % of fuel energy that is directly added to the feedwater and not otherwise lost or used. Blowdown Rate is the % of incoming feedwater mass flow rate that leaves the boiler as a saturated liquid at boiler pressure.
The steam boiler/turbine CHP approach on the left has been the most widely used CHP system to date. In this approach, a boiler makes high-pressure steam that is fed to a turbine to produce electricity. However, the turbine is designed so that there is low-pressure steam left over to feed an industrial process.
The boiler 18 is preferably operated at near stable stoichmetric conditions with about ten percent excess air. The heat of combustion of the boiler 18 is to a large degree transferred to the steam turbine while the boiler combustion products are combined with fresh air (from the compressor 60) and fuel in the combustor 44 where all remaining fuel is burned.
The feedwater heater uses steam extracted from the steam turbine to heat the boiler's incoming water. The net effect of this process is improved boiler efficiency and a lower plant heat rate.

Steam (or heat equivalent) assumed at 150 psig (10.3 barg), saturated conditions. However, the gas turbine based CHP can easily generate higher or lower pressure steam with or without superheat, hot water, drying, and/or cooling. Actual plant savings can vary dramatically based on location and application factors.

Superheated steam has its applications in, for example, turbines where the steam is directed by nozzles onto a rotor. This causes the rotor to turn. The energy to make this happen can only have come from the steam, so logically the steam has less energy after it has gone through the turbine rotor.

separation of the wet steam on saturated water and steam does not require complicated technical devices. 1. Introduction. Steam, gas and combined cycle turbine power plants are generating major part of the energy used by humanity. Thus increase of their efficiency is important. Steam turbine plants are characterized by
water, steam, or combustion exhaust. Absorption chillers are often exhaust fired using thermal energy recovered from combined heat and power (CHP) prime movers (e.g., recip-rocating engines, microturbines, and combustion turbines). Table 1. provides an overview of absorption chiller use in CHP applications. Applications. Absorption chillers use
Steam is generated in the boiler, expanded through a steam turbine, and recirculated through a condenser system cooled by a wet cooling tower. Engineering studies for an International Energy Agency project for the design and construction of a 500 kW solar thermal electric power generation system of the distributed collector system (DCS) type
When steam comes out of the exhaust vent of a turbine, it goes into a condenser where it is sufficiently cooled to condense back into water (see Figure 1). This creates a negative pressure on the back side of the turbine as well as a larger pressure differential from the inlet, which helps prepare the water to be sent back to the boiler and
