Steam Boilers

Definition of Boiler
        Steam boiler or simply a boiler is essentially a closed vessel into that water is heated till the water is regenerate into steam at needed pressure. this can be most elementary definition of boiler.
Working Principle of Boiler
        The basic rule of boiler terribly, is extremely very easy and simple to grasp. The boiler is actually a closed vessel inside that water is keep. Fuel (generally coal) is bunt in a furnace and hot gasses are created. These hot gasses are available in contact with water vessel where the heat of those hot gases transfer to the water and consequently steam is created in the boiler. Then this steam is piped to the rotary engine of thermal powerhouse. There are many various varieties of boiler used for various functions like running a production unit, sanitizing some space, sterilizing instrumentation, to heat up the environment etc.
Steam Boiler efficiency
       The % of total heat exported by outlet steam in the heat content provided by the fuel (coal, oil, gas etc.) is named steam boiler efficiency.

It includes with thermal efficiency, combustion potency & fuel to steam efficiency. boiler potency depends upon the scale of boiler used. A typical potency of boiler is 80th%  to 88th% really there are some losses occur like incomplete combustion, diverging loss occurs from boiler encompassing wall, defective combustion gas etc. Hence, potency of boiler provides this result.
Types of Boiler
    There are in the main 2 types of boiler – water tube boiler and fire tube boiler.
Fire Tube Boiler: there are the numbers of tubes through that hot gases are passed and water surrounds these tubes.

Water tube boiler is reverse of the fire tube boiler. In the water tube boiler, the water is heated within tubes and hot gasses surround these tubes.

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…
