The boiler adopts an environmentally friendly combustion method - full premixed combustion, and the gas and air are precisely adjusted and premixed in advance to ensure more complete combustion.
The boiler adopts a double-drum longitudinal "D" type arrangement structure; water, steam or steam-water mixture flows in the pipe; flame burns and flue gas flows outside the pipe, forming extremely fast steam-water.
Vacuum pumps are used to improve the efficiency of steam heating systems in many ways The most important consideration is Air actually acts as an insulation It inhibits the flow of steam and reduces its heat transfer capabilities
· Boiler mountings are a set of safety device installed for the safe operation of a boiler There are seven main mountings on a shell; steam stop valve vent valve pressure gauge water level indicator feed check valve and fusible plug These equipment save the boiler from damage due to extreme pressure steam back flow shell collapse due to unregulated steam
The of the being maintained in the steam condenser: 1 By maintaining a in the steam condenser the efficiency of the steam-power plant can be increased as greater the in the system greater will be the enthalpy drop of steam Therefore more work will be available per kg of steam condensing 2
A vacuum pump or steam ejector is used to These types of systems are common on very large boilers that operate at high pressures for steam turbine power generation
Vacuum principle Here an ejector pump is used to create a vacuum in the tank This causes the to because of which This principle is normally used for steam turbine applications Economizer Historically economizers have only been used in large-scale power plants
to pull rather than push condensate Also having hot condensate returned not only saves energy but also reduces the steam load on the which can be extremely in plants where the steam demand is already near the capacity of the system Still there are plants that do not recover all of their condensate
Steam sparging in the condenser hotwell complements the use of auxiliary boiler and condenser vacuum pumps to degasify condensate in hotwells during short-term shutdown and to more rapidly degasify during ramp-up ramp-down and part-load operation
A vacuum on a boiler can Preventive Measures In conclusion some common practices that should be followed in order to
The most common source of corrosion systems is dissolved gas: oxygen carbon dioxide and ammonia Of these oxygen is the most aggressive The of eliminating oxygen as a source of pitting and iron deposition cannot be over-emphasized Even small concentrations of this gas can cause serious corrosion problems
