EXAMPLE 114 BOILER/TURBO-GENERATOR SYSTEM OPTIMIZATION Linear programming is often used in the design and operation of steam systems in the chemical industry. Figure El1.4 shows a steam and power system for a small power house fired by wood pulp. To produce electric power, this system contains two turbo- generators whose characteristics areGet price
Trevithick was the first to successfully use high-pressure steam (then known as "strong" steam). Until ca. 1800, the weakness of existing boilers coupled with the influence of James Watt had generally restricted steam boilers to very low pressures or "weak" steam.Get price
Water Tube Boilers Used for high pressure high capacity steam boiler Available in sizes that are far greater than the fire tube design. Up to several million pounds per hour of steam. Able to handle higher pressures up to 5,000psig Recover faster than their firetubeGet price
Cost-Effective Power Generation In a backpressure steam turbine, energy from high-pressure inlet steam is efficiently converted into electricity, and low-pressure exhaust steam is provided to a plant process. The turbine exhaust steam has a lower temperatureGet price
2015/3/17 · 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.Get price
"Steam produced from a boiler drives a steam turbine, which in turn drives the electric generator. The low- pressure exhaust steam from the turbine is supplying the required heat to the process. The condensed steam from the process is then returned to the d.Get price
Condensate leaves the condenser at 4.5 kPa, 25 o C and is pumped to 18.5 MPa before entering the steam generator. The pump efficiency is 77%. Determine (a) the net work per unit mass of steam flow, (b) the heat transfer per unit mass of steam passing through the boiler, (c) the thermal efficiency and (d) the heat transfer per unit mass of steam passing through the …Get price
