1 25 mpa steam coal boiler

Thermo problem set no. 2 - SlideShare

Dec 17, 2017 · A BP2-94. A back pressure steam turbine of 100 MW capacity serves as a prime mover in a cogeneration system. The boiler admits the return water at a temperature of 66oC and produces the steam at 6.5 MPa and 455oC. Steam then enters a back pressure turbine and expands to the pressure of the process, which is 0.52 MPa.

Boiler Efficiency - an overview | ScienceDirect Topics

P. GoldsWorthy, E. On, in The Coal Handbook: Towards Cleaner Production: Coal Utilisation, 2013. Boiler efficiency and carbon burnout. Boiler efficiency is a measure of how effectively chemical energy in fuel is converted into heat energy in steam going to the turbines. The largest boiler efficiency loss is sensible heat lost as hot flue gases (and ash) exit the boiler.

Cogeneration - Wikipedia

A combined cycle (in which several thermodynamic cycles produce electricity), may also be used to extract heat using a heating system as condenser of the power plant's bottoming cycle.For example, the RU-25 MHD generator in Moscow heated a boiler for a conventional steam powerplant, whose condensate was then used for space heat. A more modern system might use a gas turbine powered by …

The boiler pressure was also increased to 200 psi (1.38 MPa). They shared with the Gresley K3 class the record for the largest diameter boiler in Britain, at 6 ft (1.83 m ). Also, because of the great length of their parallel boilers, the locomotives earned the nickname 'Skittle-alleys'.

Open Cycle Gas Turbine - an overview | ScienceDirect Topics

Radiation and oil-cooler losses only amount to 1–2%. The waste gas is clean – nearly all air at over 500°C on full load. If the waste gases were passed through a waste-heat boiler to generate steam, the 1.25 MW set could generate some 4500 kg/h at 1.75 MPa gauge, raising the combined electrical and steam-generation efficiency to around 50%.
