The pump head refers to the capability of the pump to move the water through the loop and all the resistance in the loop or friction of the loop. Another method for determining pump head is to measure the longest pipe run in the loop and then adding the friction loss for each valve, elbow,


The flow of steam of a higher toward a lower pressure increases as the difference in pressure increases to a point where the external pressure becomes 58 per cent of the absolute initial pressure. Below this point the flow is neither increased nor decreased by a reduction of the external pressure, even to the extent of a perfect vacuum.

How Do Steam Boilers Work? | Hunker

Mar 28, 2019 · The way that a steam boiler works is a straightforward process that aligns with the natural heating, cooling and condensation process.

Flow-Through Boiler | Article about Flow-Through Boiler by

Flow-Through Boiler. In a flow-through boiler a circulation pump feeds water to an economizer. The water then passes to the coils or rising pipes, which constitute the evaporative surface and are located in a combustion chamber. In the output part of the coils any remaining moisture is evaporated, and the superheating of the steam begins.


These boilers, in contrast to recirculation or natural circulation units, are characterized by continuous flow paths from the evaporator inlet to the superheater outlet without a separation drum in the circuit.

flow through sream boilers

The flow of steam to the plant. When steam condenses, its volume is dramatically reduced, which results in a localised reduction in pressure. This pressure drop through the system creates the flow of steam through the pipes. The steam generated in the boiler must be conveyed through the pipework to the point where its heat energy is required.

Boiler (power generation) - Wikipedia

The steam piping (with steam flowing through it) is directed through the flue gas path in the boiler furnace. This area typically is between 1,300–1,600 °C (2,372–2,912 °F ). Some superheaters are radiant type (absorb heat by thermal radiation ), others are convection type (absorb heat via a fluid i.e. gas) and some are a combination of the two.

Steam Heating Process - Load Calculating

In flow type applications the product or fluid is heated when it constantly flows over a heat transfer surface. Non-flow or Batch Heating. In non-flow type applications the process fluid is kept as a single batch within a tank or vessel. A steam coil or a steam jacket heats the fluid from a low to a high temperature.

Mar 19, 2018 · This water is then fed to the boiler through economiser. In the boiler, the water is converted into steam. This steam then goes to the super-heater, where the steam is heated up to the superheating temperature. The superheated steam then goes to the turbine through a series of nozzles. At the outlet of these nozzles, the high pressure and high-temperature steam suddenly expands and hence gets kinetic energy.
