Smoke Tube Boiler ( Internal Furnace Smoke Tube Boiler) internal design, most of the radiative combustion heat is transferred to the surrounding water and only small amount of heat is lost to the environment which can also be taken care using various techniques.Our Internal Furnace Smoke Tube Boilers - Intech Model
Air Preheater tubes are essentially a type of Heat exchanger tubes use for the purpose of heating air which is further used in other applications like Boilers, Dryers etc.An air preheater (APH) is a general term used to describe any device designed to heat air before another process (for example, combustion in a boiler ) with the primary objective of increasing the thermal efficiency of the
High pressure boilers for process steam - once-through feed - are indirectly heated to save cost on water treatment. e.g: Plywood industries using steam for drying, peeling/treating, plying etc. Incidentally, the condition of steam can be closely
Boiler Tube Leakage is major cause of outage of units and generation loss in thermal power plant. Detection of boiler tube leakage is very important factor for power plant functioning. Power plant engineers must remain vigilant about boiler tube leaks so that secondary damage to pressure parts such as water wall, super heater tubes and furnace refractory may be avoided due to impact of leaking
Stay tubes are the ones in a boiler which give support to the end plates. The wall thickness of stay tubes higher than the normal tubes. I hope is answer to your question. If I am not mistaken, you are a marine engineer and this information is par
2019-9-18 · A high pressure watertube boiler is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which heats water in the steam-generating tubes. In smaller boilers, additional generating tubes are separate in the furnace, while larger utility boilers rely on the water-filled tubes that make up the walls of the furnace
