INTERNAL FURNACE PACKAGED TYPE TOP FEED BOILER


v THERMODYNE ď ˝

Internal Furnace Top Feed Husk Fired Boiler is said so because of their unique automatic fuel feeding from the top of the Internal Furnace boiler. Until now automatic feeding was only possible in case of an external furnace where the furnace is not a part of the boiler.

INTERNAL FURNACE BOILER

The combustion of fuel takes place in furnace provided inside the boiler shell. Hence due to radiation, the heat transfer to the water side is most efficient & complete.

Since the rate of heat transfer at higher temperature difference is more, the internal furnace which is completely immersed in water, offers the best possible and most efficient heat transfer design possible

AUTOMATIC FEEDING IN BOILER Rice Husk is fed into a hopper placed above the ducting, connecting the boiler at one end and the Forced Draft Fan at the other. Fuel feeding is regulated according to the steam capacity requirement and the fuel is regulated by the air flow through a forced draft fan.

FULLY WET-BACK / SEMI- WET BACK DESIGN The boiler can be offered to you is a 3-pass Semi-Wet back design boiler in which the reversal chamber for flue gases between 1st & 2nd pass is provided inside the boiler shell. Hence the radiation losses due to refractory lined reversal chamber in the back end smoke box are eliminated as the complete heat of the furnace is transferred to the water inside the shell. This increases the efficiency and reduces maintenance & break-down costs.

 

LARGE GRATE AREA Inadequate grate area causes high percentage of combustibles in ash as the air and fuel mixing is not proper. This results in higher fuel consumption and thus a drop in efficiency of the boiler. Large grate area ensures that the required amount of fuel is able to burn in the most efficient manner inside the furnace of the boiler thereby reducing your fuel bills. This whole area is easily reachable and thus whole of the grate is utilized for effective combustion.


v THERMODYNE

LARGE HEATING SURFACE AREA Large Heating Surface Area ensures that you get guaranteed output and as the evaporation per unit area is optimum, the thermal stresses on the boiler are minimum. This ensures longer life and trouble-free operation of the equipment

IN-BUILT AIR PRE-HEATER WITH FD FAN A unique design feature - In-built Air Preheater assembly can be provided, which provides pre-heated combustion air for fuel combustion. The air being fed to the furnace for combustion of fuel is pre-heated utilizing the waste heat of flue gases going to the chimney, there-by recovering useful heat from the gases and reducing stack loss. This results in higher efficiency and lower fuel consumption.

IN-BUILT WATER PRE-HEATER Another unique feature of our boilers is the Water Preheater assembly provided on the back side smoke chamber. The feed water gets preheated before going into the boiler and hence increases the efficiency of the Boiler System. Another advantage is that the maintenance requirement for refractory at the back end smoke box is eliminated there-by reducing the break-down time and maintenance cost. The radiation losses due to refractory lining are also reduced, which increases the overall efficiency of the boiler.

ASH DISCHARGE PORTS Ash doors are provided after each flue gas pass to facilitate easy removal of ash in the flue gases without having to open the smoke doors of the boiler. An ash door is provided in the furnace bottom for removal of ash before it enters the fire tubes. This ensures trouble free operation and lesser deposition in the tubes thus reducing downtime and maintenance cost.
