Abstract: 217,943. Loftus, F. H. Jan. 22, 1923. Gaseous-fuel furnaces.-In an openhearth regenerative furnace, gas is delivered alternately at each end of the furnace through a removable refractory water-cooled nozzle 24 across the air uptake 29 and enters the mixing-chamber 30 with air to effect mixing and complete combustion of the mixture upon entering the furnace chamber 31. An auxiliary supply of air passes from the uptake 29 and through a channel 33 extending over the top and down the sides of the mixing-chamber to form a protecting blanket for the roof and side walls. Gas is drawn alternately through the end nozzles 24 by an inducing stream of air delivered by a fan 11 through nozzles 20, 21. According to the position of the valves 34, 35, which are actuated by the operator from the working-platform, hot air is drawn from one or other of the air regenerator slag pockets 16, 17 through the pipe 14 or 15, and, after being mixed with cold air to reduce the temperature, is delivered through the pipe 19 or 19<1> to the nozzle 20 or 21. In an alternative arrangement, instead of hot air being drawn from the slag pockets at the inlet end of the furnace, waste gases may be withdrawn from the slag pockets at the outlet end of the furnace and supplied to the nozzles 20, 21 mixed with cold air. In the event of the fan being inoperative, steam or compressed air from a separate source may be supplied to the nozzles 20, 21. The valves 34, 35 are each provided with a central aperture to allow for a small supply of air to the nozzle 24 at the outlet end of the furnace to protect the nozzles. The nozzles 24 and mixing-chamber 30 are elliptical in cross-section and are provided with constrictions as shown. The nozzles 24 are mounted in sealing-troughs 23 and are adjustable.

Title: Process for the production of granules of cyanamide with a high nitrogen content
IPC: C05C7/02
Filed: 1922-01-23
Abstract: Stable granules of calcium cyanamide are made by making a homogeneous paste with about 15-20 per cent of water while avoiding too great a rise of temperature and moulding under very high pressure by passing the paste between two rollers rotating in opposite directions, one roller being perforated with a number of holes which may advantageously decrease in size from outside to inside.  The cynamide is forced through the holes and breaks off into pieces on the inside. They are allowed to harden in thin layers.  Instead of water, a strong solution of calcium nitrate may be used to make the paste, in order to increase the nitrogen content of this product. Specification 151,989 is referred to.
