Abstract: 681,326. Solid fuel stoves. FORGES DE CINEY SOC. ANON. Aug. 31, 1950, No. 21554/50. Class 126 In a domestic heating stove burning coal having a high volatile content and having a hopper feeding fuel to the grate as combustion progresses, the volatile gases released in the hopper are conducted through a passage into a zone where the flames leave the furnace chamber and air is supplied to that zone so that the gases are burned. The stove comprises a fuel hopper with a divergent lower portion 2. The front wall 5 of the hopper is provided over the whole of its height with holes 6. Volatile gases evolved in the hopper pass through the holes 6 and down a passage 7 between the wall 5 and the flue to the combustion zone. Air heated in a space 4 at the rear of the hopper passes into the hopper through restricted holes 8. The fuel burns in a space bounded by a grate 9, comprising a raking device or the like, the lower end of the front wall 5 of the hopper and a front plate 10, supplied with primary air from the ash pit. Flames escaping between the bottom of perforated wall 5 and front plate 10 ignite the gases from the passage 7, secondary air being supplied below front plate 10 through an adjustable opening 18 in the fire door. The combustion products pass out of the stove through passages 15 surrounding the hopper. External air may be heated in passage 16. An outer fire door 20 with vertical bars allows combustion to be observed through mica 22 in the inner fire door.

Patent GB-2018818-A (GB)
Title: A process for preparing a methane-rich gas
IPC: B01J23/00
Filed: 1979-04-09
Abstract: The invention relates to a methanation process wherein a preheated synthesis gas stream consisting of hydrogen and carbon monoxide generally in the proportion 3:1 v/v is combined with a recycle stream from the methanation reactor and the combined stream is passed through a nickeliferous bed of methanation catalyst in a methanation reactor. The economy of such process is improved by reducing the recycle ratio; and to obtain this the temperature of the combined inlet stream according to the invention is maintained between 175 and 250 DEG C. Under normal circumstances low temperatures would destroy the nickel catalyst and to avoid this the invention prescribes that a layer of shift catalyst is placed in the methanation reactor, directly ahead of the nickeliferous methanation catalyst. <IMAGE>
