Pulverised Coal - an overview | ScienceDirect Topics

Biomass and other materials, like waste, can also be added to the mixture. Coal contains mineral matter that is converted to ash during combustion. The ash is removed as bottom ash and fly ash. The bottom ash is removed at the furnace bottom. This type of boiler dominates the electric power industry, providing steam to drive large turbines.

Superheaters - an overview | ScienceDirect Topics

Esa Kari Vakkilainen, in Steam Generation from Biomass, 2017. 7.2.1 Radiative Superheater. Radiative superheaters are used as the first heat transfer surfaces after the furnace. Often a platen arrangement is preferred to create a fouling-resistant construction. Spacing in the first superheaters can be from 150 to 1000 mm. Superheaters are the hottest heat transfer surfaces in the boiler, so

How do you calculate the Power generation in steam Turbines??

We have excess air EA = O2 X 100 / (21-O2) EA = 4.7 X 100 / (20-4.7) EA = 30.71% 2-Calculate the Oxygen level (O2) in flue gas, if excess air is 25% We have Excess air EA = O2 X 100 / (21-O2) 25 = O2 X 100 / (21-O2) O2 = 4.2% 3-A Boilers combustion system requires 5.5 kg of air for burning 1 kg of fuel, then calculate the total air required

Sep 18, 2020 · The cast iron material is more corrosion-resistant than the steel used in water-tube and fire-tube boilers. A boiler can be moved into place one section at a time through a buildings doors or windows. Due to the modular nature, the capacity of a boiler can be adjusted by changing the number of cast iron sections used. Boiler controls

Anaerobic digestion - Wikipedia

Anaerobic digestion is a sequence of processes by which microorganisms break down biodegradable material in the absence of oxygen. The process is used for industrial or domestic purposes to manage waste or to produce fuels. Much of the fermentation used industrially to produce food and drink products, as well as home fermentation, uses anaerobic digestion.
