[Class 51 (i).] A smoke burning firebridge of the type comprising a number of assembled sections providing two separate series of channels for the supply of steam and air to the combustion space has a perforated steam pipe 18 located at or near the outlets of one series of channels 7 and another perforated steam pipe 19 located at or near the inlets of the other channels 8, steam being supplied from a superheater 17 so as to create an upward draught of air through the channels 8 varying in accordance with the amount of steam supplied. The bridge sections 5 are supported on a carrier frame 1 and comprise tapering grooves 7, 8 which form channels for the outlet of steam and air when the sections are assembled side by side. Helical ribs 9 on each groove 8 form a baffle for the air and external serrated projections 13 serve to radiate heat and support plastic refractory material 14. The steam superheater 17 is arranged behind the bridge and comprises a coiled pipe cast in a bed of firebrick 17a. From the superheater the steam passes to the perforated pipes 18, 19 from which it issues through the steam channels 7 and into the air channels 8 creating an upward draught of air through the air channels. A valve in the steam supply pipe thus regulates both the steam and air flow through the bridge. Fig. 10 shows a modification in which a circuitous path is provided for the air which enters a curved passage 10 on one side of a section, passes through a hole 11 in the section and issues from a tapering passage 12 on the other side of the section. The sections may be so formed that they can be assembled with the outlets of adjacent pairs of sections pointing in opposite directions as shown in Fig. 6 ; this form is suitable for refractory furnaces for water-tube boilers. The grooves for the air and steam channels may be formed on opposite sides of each section and the outlets may lie in the top of the section.
