Title: Improvements in and relating to furnace and boiler plant
Filed: 1950-09-15
Abstract: 695,727. Boiler furnaces. WALTHER & CIE AKT.-GES. Sept. 15, 1950. [Sept. 15, 1949; Sept. 30, 1949], No. 22741/50. Addition to 683,492. Class 51(i) In a modification of the boiler furnace described in the parent Specification for carrying out the method of burning solid fuel disclosed in the said Specification coarse regulation of the combustion in the lower part of the combustion chamber in accordance with the load on the boiler and fine regulation of the combustion in the upper part of the combustion chamber in accordance with excess air in the waste gases is obtained by varying the quantity of returned waste gases supplied with the combustion air to the various points in said combustion chamber. Cold air is supplied through pipes f and a to the undergrate zone W and through pipes f and b to the ash zone R by a fan FG which also supplies heated air to the forwardly directed nozzles c over the grate in the lower part U of the combustion chamber and to the tangential nozzles h in the upper part O of the combustion chamber through pipe g, air heaters L 1  and L 2  and pipe i. A second fan RG draws waste gases from the boiler convection pass at high or low temperatures from the points m or k respectively under control of a valve o, and supplies said waste gases to the cold air pipe a under control of a valve r and to mixing valves sand r controlling the passage of mixed air and waste gases to the tangential nozzles h and the forwardly directed nozzles c respectively. A branch e controlled by valve x conveys hot air to the fuel supply shaft near the feed conveyer B and a branch t shown in broken lines and controlled by a valve u conveys waste gases to nozzles arranged between the tangential nozzles h. With this arrangement the aforementioned automatic control of combustion in the upper and lower parts of the combustion chamber by the gradual replacement of air by waste gases as the load demand drops is easily achieved. A conical baffle I, Fig. 3, having a lower aperture K in the centre is disposed between the upper part O and the lower part U of the combustion chamber, facilitating separation of the ash which tends to collect thereupon and fall through said aperture K on to the grate W, and also facilitating completion of combustion in the upper part O by causing the gases from the lower part U to pass through the annular space between the baffle and the combustion chamber wall into close proximity to the tangential nozzles h. The upper part O of the combustion chamber may also be formed with walls which widen downwardly, and the restricted off-take G is provided for the passage of waste gases to the convection pass of the boiler. Specification 672,287 also is referred to.
