The Intech boiler, as its name suggests, is a packaged boiler with a 3-pass internal furnace Packaged boiler. It is a conventional 3 smoke-tube design approach and is intended for burning coal and wood within an internal furnace. As a result, it is often referred to as a steam boiler for coal/wood combustion therefore sometimes known as coal/wood fired Steam Boiler.
The Packaged Boiler is offered in three options: dry back, semi-wet back, and fully wet-back. It is particularly well-suited for manually burning solid fuels such as coal, wood, or briquettes.
The furnace of the boiler is completely immersed in water, facilitating the efficient transfer of maximum heat from the furnace to the surrounding water. Grate bars, upon which the fuel is combusted, are positioned within the furnace to ensure the optimal grate area for effective fuel burning.
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 the Second and Third Pass Smoke Tubes, reversing from smoke boxes on their way out.
Flue gases traveling 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.
