2015-8-13 · A high pressure steam from the boiler, known as a primary fluid, expands In a steam jet refrigeration cycle as shown in Fig. 2, an ejector the boiler and at the evaporator respectively, using attached sight glasses during the certain time interval in steady operation.
2019-11-30 · Boiler and Condenser Pressures. The thermal efficiency of steam turbine tends to increase as the average steam pressure increases and/or the condenser pressure decreases. An increase in the boiler pressure is in the result limited by material of the reactor pressure vessel. Rankine cycle with superheat of the high-pressure stage. This
2019-11-27 · The thermodynamic cycle of the basic combined cycle consists of two power plant cycles. One is the Joule or Brayton cycle which is a gas turbine cycle and the other is Rankine cycle which is a steam turbine cycle. The cycle 1-2-3-4-1 which is the gas turbine power plant cycle is the topping cycle. It depicts the heat and work transfer process taking place in high temperature region.
Below 0 °C. The compressor is switched off to prevent evaporator icing. • Between 0 °C and 16 °C. From experience this is known to be the ambient temperature range where there is the highest misting risk, therefore the evaporator is run at its minimum temperature (3 °C) for maximum dehumidification, with subsequent air reheating by the PTC.

2019-11-11 · MVR Evaporator Working principle: MVR is called Mechanical Vapor Recompression. It use the centrifugal compressor to re-compress the secondary vapor(low temperature and low pressure) which is evaporated from the liquid material to rise its temperature and pressure, so as to reuse it as heating source to evaporate the liquid material again.
2019-7-5 · to a condenser or to a process. The initial turbine is designated as the high-pressure (HP) turbine and the second turbine the low-pressure (LP) turbine. For a single reheat cycle, the steam from the boiler flows to the HP turbine where it expands and is exhausted back to the boiler for reheating. The reheat steam coming from the boiler flows
2019-11-16 · A heat recovery steam generator (HRSG) is an energy recovery heat exchanger that recovers heat from a hot gas stream, such as a combustion turbine or other waste gas stream. It produces steam that can be used in a process (cogeneration) or used to drive a steam turbine (combined cycle).
'Boiler feed water pump' pumps the water at high pressure into the boiler from the 'feed water tank'. The pump is akin to the heart in the human body. Pre-Heating 'Feed water heaters', using extracted steam from the turbine, adds a part of the sensible heat even before the water enters the boiler. Economiser.
2008-1-4 · evaporator, this design has dominated the Industry for decades and remains a common sight in older Kraft mill operations. The heating element is a shell and tube heat exchanger using 2" OD tubes, typically 24ft. to 30 ft. long. Liquor is fed into the bottom liquor chamber and then into the tubes. It is heated with condensing steam on the outside
2017-8-10 · Evaporator and Recovery Boiler Energy Efficiency This is possible as the pressure on the liquor side and the boiling point go down in each successive effect, to end up with the last effect before the surface condenser mill and the efficiency of the boiler producing the steam. Using a value of $6/GJ and 2.2 GJ/t of steam,
