The remaining steam continues to expand to 6 kPa. Steam is then condensed at constant pressure and pumped to the boiler pressure of 8 MPa. Steam leaves the process heater as a saturated liquid at 500 kPa. The mass flow rate of steam through the boiler is 20 kg/s.Determine (a) the rate of process heat supply and (b) the net power developed.Get Price
Steam is a compressible gas where pipe line mass flow capacity depends on steam pressure. Sizing Steam Pipes . Steam is a compressible gas where the capacity of a pipe line depends on the size of the pipe and the steam pressure. Soft or Hard Water . Carbonates dissolved in water.

The boiler system relies on a burner to initiate the combustion process, and then heat in the form of steam or hot water moves through the system using pumps, radiators, and heat exchangers. Boiler manufacturers are making use of rapidly improving technology to build equipment that is cost-efficient, environmentally friendly, and powerful.Get Price
The steam dryness fraction is used to quantify the amount of water within steam. Dry steam - all water molecules are in the gaseous state; Wet steam - a portion of the water molecules have lost their energy - latent heat - and condensed to tiny water droplets; To produce dry steam in an boiler and keep the steam dry throughout the piping system is in general not possible.Get Price
amount of steam generated by the boiler may exceed the amount consumed by the processes. In such cases, the surplus steam is released into the atmosphere.

Fire-tube boiler Here, water partially fills a boiler barrel with a small volume left above to accommodate the steam (steam space).This is the type of boiler used in nearly all steam locomotives.The heat source is inside a furnace or firebox that has to be kept permanently surrounded by the water in order to maintain the temperature of the heating surface below the …Get Price
Steam turbine power plants operate on "Rankine cycle" for the production of electric power. If the steam from the waste heat boiler is used for process or space heating, the term "cogeneration" is the more correct terminology (simultaneous production of electric and heat energy).Get Price
Increasing the Boiler Pressure (Increase TH) Increasing the operating pressure of the boiler leads to an increase in the temperature at which heat is transferred to the steam and thus raises the efficiency of the cycle.

The boiler undergoes thermal shock when cold water is introduced to the hot surfaces of the boiler wall and its tubes. Hotter feedwater means a lower temperature difference and less risk of thermal shock. To maintain the designed output. The lower the boiler feedwater temperature, the more heat is required in the boiler to produce steam.Get Price
This heat is supplied to the boiler from the solar concentrator. There is no pressure change in the boiler, only heat transfer to the fluid; therefore, no mechanical work is done here. The next process 3-4 is expansion of the steam in the turbine. The work done through that process is the useful work, which is the main purpose of the cycleGet Price
Process 2–3: The high-pressure liquid enters a boiler, where it is heated at constant pressure by an external heat source to become a dry saturated vapour. The input energy required can be easily calculated graphically, using an enthalpy–entropy chart ( h–s chart, or Mollier diagram ), or numerically, using steam tables or software.Get Price
Tips. Having said this, it is necessary to be mindful of the following when heating with saturated steam: Heating efficiency may be diminished if steam other than dry steam is used for process heating. Contrary to common perception, virtually all of the steam generated from a boiler is not dry saturated steam, but wet steam, which contains some non-vaporized water molecules.Get Price
Then the saturated water is pumped to the boiler pressure by a second pump (state 4). The water is heated to a higher temperature in the boiler (state 5) and the cycle repeats again. The T-s diagram of this cycle is shown on the left. Note that the mass flow rate at …Get Price

Fig. 3.11 shows a simple boiler process. Fuel and the required amount of combustion air are fed into the boiler. The fuel reacts with the oxygen in the boiler and flue gas is drawn out. Released heat is captured by the water pumped into the boiler, transforming it into the steam that flows from the boiler.Get Price
