Electric steam boilers are more efficient than fire-heated boilers because they require less energy to be put into them for operation at capacity. This is because there is little energy lost when the transfer of heat from the heating element to the water occurs, unlike traditional fire heated boilers, where there is a substantial amount of ...
A boiler or steam generator is a device used to create steam by applying heat energy to water. Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a ...
In a fossil fuel power plant using a steam cycle for power generation, the primary heat source will be combustion of coal, oil, or natural gas.In some cases byproduct fuel such as the carbon monoxide rich offgasses of a coke battery can be burned to heat a boiler; biofuels such as bagasse, where economically available, can also be used.
While the traction engine was usually built using its locomotive boiler as its frame, other types of steam road vehicles such as lorries and cars have used a wide range of different boiler types. Road transport pioneers Goldsworthy Gurney and Walter Hancock both used water-tube boilers in their steam carriages around 1830.
A steam generator is a form of low water-content boiler, similar to a flash steam boiler. The usual construction is as a spiral coil of water-tube , arranged as a single, or monotube , coil. Circulation is once-through and pumped under pressure, as a forced-circulation boiler . [ 1 ]
Electrode boilers can work on both single-phase and three-phase supplies. If DC voltage is used, electrolysis of water occurs, decomposing water into its elements H 2 at the cathode (negative electrode) and O 2 at the anode (positive electrode). The electrode boiler is 99.9% efficient with almost all the energy consumed producing steam. [1]
