Steam Accumulators

Steam Accumulators
Like any other machine, boiler manufacturing has also undergone a sea-change in the last century. Today’s boilers are much more efficient than the boiler so past as there has been constant pressure on designers to make these more and more energy efficient. 

The ever increasing competition has forced the boiler users to turn to non-conventional fuels, which in turn has resulted in compact boilers to suit the demands.Today the boilers have been reduced in size as higher efficiency and quick response is the demand of the day. Compact designs are preferred so as to have lesser footprint and initial costs have also reduced as the buyers need cheaper options. However, to meet these demands, one important aspect of boiler design has been compromised i.e. water & steam holding space.

The actual energy gets stored in a boiler in form of water it holds as saturation temperature. Greater the amount of water holding volume in a boiler, greater is the energy stored which is required to answer surge demands or high instantaneous steam loads.A typical comparison between modern day packaged boiler and old model Lancashire boiler of similar capacities is mentioned below:
Boiler Type
Steaming capacity
 Volumetric capacity
Lancashire boiler  
2000 Kg/hr                    
27000 litters
Packaged boiler
2000 Kg/hr
5000 litters
The modern packaged boiler contains only 20% of the water held in a similar capacity Lancashire boiler, which means that the energy stored in this is only 1/5th of the energy stored in the Lancashire boiler. Hence a modern packaged boiler would not be able to meet the sudden surge in steam demands from the process as an old boiler could.
The Steam demands on any process industry is never steady, it keeps on fluctuating during the day. Usually industries which work in batch processes are the ones where there are crests and troughs in steam demands like Laminates, dandified plywood, Metal Forging, Thermocole etc.
Due to this peak demand, the pressure inside the boiler falls immediately, thereby causing loss of production due to increase in process time. Other negative results are low boiler efficiency and reduced boiler life. To counter this sudden demand, the process industry managers use staggering technique wherein they stagger the production processes to keep steam demands under control. But this results in lower production, which is detrimental to the overall health of the process industry.

4 MAJOR ADVANTAGES OF AIR PREHEATER IN BOILER

4 MAJOR ADVANTAGES OF AIR PREHEATER IN BOILER:
1.Increased thermal efficiency
2. Short payback period & increased combustion rate
3. In the case of combustion of pulverized coal hot air can be used for drying the coal as well as for burning the coal efficiently
4. All standard fuels and even lower grades of coals can be burnt efficiently with hot air

Thermodyne Boilers is a successful manufacturing the Boiler accessories like Air Preheaters, Economizers, Superheaters etc.

What is Wet Scrubber?

Wet Scrubbers are the pollution control equipment that helps in controlling the pollution by reducing the concentration of pollutants such as Sulfur dioxide (SO2) and ash content in exhaust flue gases.
As the pollution norms are getting stringent and the government is making sure that pollution laws are being implemented, many industries are coming up with various solutions and strategies for reducing the pollution and its management. One such solution is using pollution control equipment such as Wet Scrubbers.

Industries or power plants generally have boilers or furnaces installed in their processes where combustion of fuel is taking place. Combustion of fuel generates flue gases that contain a large amount of heat which is transferred to water to convert into steam. These fuels generally contain carbon, sulfur, hydrogen, oxygen and on combustion with air, they form flue gases containing Sulfur dioxide (SO2), Carbon dioxide (CO2), Ash, Water vapor (H2O). Out of these SO2 and Ash …

Why Do We Need A Fusible Plug?

Fusible Plug is a fitting used in Steam Boilers to enhance the safety during operation. It’s working depends upon the water level in the Boiler shell. A fusible Plug is a threaded metallic cylindrical object, with a tapered hole in it which goes through its entire length. It is usually of brass, bronze or even gunmetal. In a smoke tube steam boiler, it is fitted on the front tube sheet, just above the tubes (used for flue gas flow) arrangement but below the perforated feed line inside the shell.


But the question is how exactly this little thing helps in preventing a huge disaster. It’s working is dependent only on the temperatures not on pressures. What happens is that during steam boiler operation, the feed pumps to supply water for steam conversion in the Boiler shell on the basis of the signal sent to it by the electrical panel. And electrical panel receives this signal from the mobrey (automatic water level controller) based on the fluctuating water levels due to conti…
