Contact SupplierIntech as it’s name implies is a 3 Pass Internal Furnace Packaged Boiler. It is a conventional 3 pass smoke-tube design, designed for the combustion of coal and wood in an internal furnace and is therefore sometimes known as coal/wood fired Steam Boiler.
This Packaged Boiler comes in dry back, semi-wet back, and fully wet-back options and is most suitable for a manual firing of Solid Fuel like coal, wood or briquettes.
Â
The boiler furnace is fully submerged in the water, this helps in transferring the maximum heat from the furnace to the surrounding water. The grate bars on which the fuel is burnt are placed in the furnace to ensure desired grate area for burning fuel.
The fuel of Packaged Type Boiler is fired on the grate and flue gases are released on combustion of fuel. The flue gases then travel from the furnace to the flue gas outlet through theSecond and Third Pass Smoke Tubes, reversing from smoke boxes on their way out. Flue gases travelling at high speed ensures maximum convective heat transfer rate and 3 passes (2 tube passes and 1 furnace pass) extract the maximum amount of heat from the gases. An induced draft fan is provided in the Boiler Assembly, for proper combustion and maintaining draft in the furnace. This conventional design also ensures effective distribution of thermal and mechanical stresses in the heating equipment thereby increasing the boiler life.
Water pre-heater or Economiser may be provided in a shell and tube design to increase the efficiency of a boiler. This implies recovering waste heat from flue gases by reducing the exhaust temperature leaving the boiler.
