A chimney may be a structure that provides ventilation for decent flue gases or smoke from a boiler, stove, chamber or hearth to the surface atmosphere. Chimneys are generally vertical, or as close to as attainable to vertical, to make sure that the gases flow swimmingly drawing air into the combustion in what is called the stack, or chimney, effect. The area within a chimney is named a flue. Chimneys are also found in buildings, steam locomotives and ships. in the USA, the term stack (colloquially, stack) is additionally used once concerning locomotive chimneys or ship chimneys, and therefore the term funnel may be used. Self-supported type chimneys may be provided suiting the boiler size. These can be designed and manufactured as per IS-6533 standard to ensure compliance.
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.
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
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
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…
