Fire Tube Boilers

Fired Tube Boilers
Dual Furnace Fired-Tube Boiler

The fire-tube boiler developed because the third of the four major historical types of boilers: low-pressure tank or "haystack" boiler, flue boilers with one or 2 massive flues, fire-tube boilers with several little tubes, and high-pressure water-tube boilers.
The advantage of boiler over fluid boilers with a single massive flue is that the various little tubes provide way larger heating surface area for an equivalent overall boiler volume. the final construction is as a tank of water penetrated by tubes that carry the hot flue gases from the heart. The tank is typically cylindrical for the foremost part—being the strongest sensible form for a pressurised container—and this cylindrical tank is also either horizontal or vertical.
This type of boiler was used on nearly all steam locomotives within the horizontal "locomotive" kind. This encompasses a cylindrical barrel containing the fireplace tubes, however also has an extension at one finish to deal with the "firebox". This furnace has associate degree open base to produce an oversized grate space and infrequently extends on the far side the cylindrical barrel to create a rectangular / tapering enclosure. The horizontal fire-tube boilers are also typical of marine applications, using to the Scotch Boilers. Vertical boilers have also been designed to the multiple fire-tube kinds, though these are relatively rare; most vertical boilers were either fluid or to cross water-tubes.

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 Combi Boiler?

combi boiler or combination boiler is the most commonly used boiler in India. Combi Boiler is a unique membrane design water wall type boiler which combines the advantages of both water tube & smoke tube steam boilers. A combination type of steam boiler is the one which has the operational characteristics of both smoke tube and water tube steam boiler respectively. Unlike the packaged type Boilers, here the furnace is external to the boiler shell. During its operation, the combustion takes place in the water wall so the flue gases from here travel through this membrane (as in a Water Tube Boiler) and enter the Boiler shell. Now the flue gases travel in the smoke tubes (as in a Smoke Tube Boiler)
During its course of motion, it transfers heat to the – Water present in the tubes in the Water Wall MembraneWater present in the Boiler shell through tubesThis type of steam boiler offers the high degree of reliability and trouble-free operation. They effectively operate at moderately hig…
