The invention of the recovery boiler by G.H. Tomlinson in the early 1930s was a milestone in the advancement of the kraft process. [1] Recovery boilers are also used in the (less common) sulfite process of wood pulping; this article deals only with recovery boiler use in the kraft process.
It is recommended to name the SVG file “Bedforms under various flow regimes.svg”—then the template Vector version available (or Vva) does not need the new image name parameter. Summary Description Bedforms under various flow regimes.pdf
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. Steam produced in a boiler can be used for a variety of purposes including space heating, sterilisation, drying, humidification and power generation. The temperature or condition of steam required for ...
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 ...
A schematic process flow diagram of a basic 2+1-reactor (converter) SuperClaus unit is shown below: Schematic flow diagram of a straight-through, 3 reactor (converter), Claus sulfur recovery unit. The Claus technology can be divided into two process steps, thermal and catalytic.
English: HMS Belfast, diagram of the boiler. The water comes (8), and goes into pipes (9). The water comes (8), and goes into pipes (9). Warmed by the combustion of the fuel (came in 3), steam bubbles forming in these pipes, and arrives in the drum (7).
Description: 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 percentage of the total cycle steam mass flow used for the feedwater heater is termed the extraction fraction [4] and must be carefully optimized for maximum power plant thermal efficiency since increasing this fraction causes a decrease in turbine power output. Feedwater heaters can also be "open" or "closed" heat exchangers. An open heat ...
