Packaged Boiler: Intech Boiler. Intech 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,
The York-Shipley 3-Pass Wetback model of firetube boiler is built with an offset furnace and large combustion chamber. The wetback design reduces the amount of refractory in the boiler, providing additional opportunity for heat to be transferred to the boiler's stored water.
In fire-tube boilers, the flue gas passes inside boiler tubes, and heat is transferred to water on the shell side. A dynamic model has been developed for the analysis of boiler performance, and Matlab has been applied for integrating it.
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.
In this work, we are interested to simulate the transient thermal-hydraulic behaviour of 3-pass fire-tube boiler during a cold start-up. A transient thermal model has been developed based upon energy balance equations of the main components of the boiler and the relevant correlations describing heat transfer phenomena taking place.
The Scotch Marine Boiler is a firetube boiler, in that hot flue gases pass through tubes set within a tank of water. The general layout is that of a squat horizontal cylinder. One or more large cylindrical furnaces are in the lower part of the boiler shell. Above this is a large number of small-diameter fire-tubes.

In a scotch boiler, the furnace is a large diameter tube, within the boiler, surrounded by water. Some older, large scotch boilers had two or three furnaces but modern boilers typically have only one. Scotch boilers may be two-pass, three-pass, or four-pass depending upon the arrangement of baffles and tubes.
The efficiency of a boiler is governed chiefly (1) by the amount of heating surface exposed to the flames; (2) by the distribution of the heating surface; (3) by the amount of fuel which can be burnt in the furnace in a given time; (4) by avoiding wastage of heat. The simplest form of boiler, depicted in Figure 78, is extremely inefficient because of its
2019-3-13 · A fire-tube boiler is a type of boiler in which hot gases pass from a fire through one or (many) more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction, heating the water and ultimately creating steam.
The package boiler is usually a two or three-pass fire-tube boiler with an internal furnace tube. This is similar to the much earlier Scotch boiler . Generating tubes filled with water are in direct contact with the heat source inside the boiler, causing damage to the pipes as well as scaling.
