Fire-tube boilers may be designed for vertical, inclined, or horizontal positions. One of the most generally used types is the horizontal-return-tube(HRT) boiler. In the HRT boiler, part of the heat from the combustion gases is transferred directly to the lower portion of the shell. The gases then make a return pass through the horizontal tubes or flues before being passed into the stack.  2, fiche 1, Anglais, - horizontal%20return%2Dtube%20boiler

The... horizontal return tube boiler... gets it's name from the horizontal fire tubes which run back-to-front through the lower half of the boiler drum. The gas burner is located under the front half of the boiler drum. The hot gases then pass to the rear of the fire box where they turn round and return to the front via the fire tubes and into the smoke box.(see this picture for a clearer description).  4, fiche 1, Anglais, - horizontal%20return%2Dtube%20boiler

Next form of haulage at Cwmdu Colliery was the installation of a small winch in October 1934. The steam to drive this winch was provided by a vertical boiler, 8 feet high and 5 feet in diameter. A small engine house had been constructed from round bush poles, roofed with galvanised corrugated iron, and it had a concrete floor... The Cwmdu Colliery syndicate had planned to replace its early vertical boiler with the horizontal boiler to give the mine an increased flow of steam power.  2, fiche 7, Anglais, - vertical%20boiler

Horizontal Rotary-Atomizing Burner. ... The burner consists of an atomizing or spinner cup, and air blower, and a region in which the air and oil are mixed. The cup, which is mounted on a horizontal motor shaft, is revolved at a speed of 3,450 revolutions per minute or higher. The oil fed to the cup is atomized by whirling the oil off the edge of the cup. As the oil droplets leave the edge, they are caught up in a horizontal air current from the blower. The resulting fuel-air mixture is ignited by a gas pilot near the cup, and the flame is projected horizontally.  2, fiche 11, Anglais, - horizontal%20rotary%20cup%20oil%20burner

Steel boilers are fabricated into one assembly of a given size and rating, usually by welding. The heat exchange surface past the firebox usually is an assembly of vertical, horizontal, or slanted tubes. The tubes may be firetube(flue gas inside, heated fluid outside) or watertube(fluid inside). The tubes may be in one or more passes. As with cast-iron boilers, dry base, wet leg, or wet base design may be used. The majority of small steel heating boilers are of dry base, vertical firetube design. Larger boilers usually have horizontal or slanted tubes; both firetube and watertube designs are used. A popular design for medium and large steel boilers, is the Scotch, or Scotch Marine, which is characterized by having a central fluid-backed cylindrical firebox, surrounded by firetubes in one or more passes, all within the outer shell.... Steel boiler sizes range from approximately 14. 7 kW(150 mBh) to the largest boilers made.  2, fiche 12, Anglais, - steel%20boiler
