A sectional diagram of a typical steam boiler feed injector, simplified to show the major parts common to such injectors, showing typical proportions, and using colour and shading to hint at temperature, pressure, and velocity variations in the fluid flows. The SVG was hand coded using a text editor.
A piping and instrumentation diagram (P&ID) is defined as follows: A diagram which shows the interconnection of process equipment and the instrumentation used to control the process. In the process industry, a standard set of symbols is used to prepare drawings of processes.
High pressure steam enters, red, and exhausts, yellow. The uniflow type of steam engine uses steam that flows in one direction only in each half of the cylinder. Thermal efficiency is increased by having a temperature gradient along the cylinder. Steam always enters at the hot ends of the cylinder and exhausts through ports at the cooler centre.
Sections of a steam locomotive showing the many fire-tubes which carry the hot gases of the fire through the boiler to heat the water and so create steam. Boiler design is the process of designing boilers used for various purposes. The main function of a boiler is to heat water to generate steam.
A recuperator is a special purpose counter-flow energy recovery heat exchanger positioned within the supply and exhaust air streams of an air handling system, or in the exhaust gases of an industrial process, in order to recover the waste heat. Generally, they are used to extract heat from the exhaust and use it to preheat air entering the ...
The internally rifled (also known as ribbed) tubes are used in boilers and heat exchangers to improve the efficiency of heat transfer. The rifling imparts a centrifugal force to the flowing fluid (commonly a mixture of steam and water). This separates water from the mixture, forces the water towards the wall, and prevents formation of a steam ...
The compressor increases the flow of hot air which increases the rate of heat transfer to the water in the boiler tubes causing more steam to generate. The steam is used to turn a steam turbine which is coupled to an electrical generator. [3] The combustion chamber of the Velox could produce flue gasses by burning fuel gasses or heavy fuel oil.
Both effects will reduce the pipe's overall thermal efficiency when used as a heat exchanger. Boiler feedwater is the water which is supplied to a boiler. The feed water is put into the steam drum from a feed pump. In the steam drum the feed water is then turned into steam from the heat. After the steam is used, it is then dumped to the main ...
