It is not supposed that the position of other consumers of coal is very different, It an attempt were made to purchase coal of a type which would be more likely to be free of Aeletorious products, the cost of production in all forms of industry would Increase, and with a concern like 'ithe Shanghai Power Company this would be & most serious matter, not so much in respect of the current used by the residential consumer, but of the bulk consumer, who might be faced with the choice of putting in his own plant or paying something like 80 per cent. more fox his power. The economic effect of such a condition can readily be imagined, The Power Company is experlmenting with the intention of apply-{ing a special treatment to No, 3 voller The ash and sulphur elimin pulverized fuel boller known a8 No, 4, is considered to be'satisfactory as a'result of com-plote and exhaustive tests carried out fon the grit washers of this boller house during the summer and autumn of 1935. These tests showed that 85 to 90 per cent, of the fly ash and 91 to 90 per cent, of the sulphur are eliminated in the operation of this boiler house which, in 1985, consumed 322,114 tons of coal, or Oi per cent, fof the total coal consumed by the plant, The success of this treatment in No, 4 does not necessarily mean that success in dealing with No. 3 assured, The character of the coal used for the boller houses Is of course dependent upon the particular kind fof plant. installed, and where No. 4 boiler house can tse pulverized fud, in the other boiler houses coal has to be fed by means of stokers, and the Company has to depend mainly on Shantung coals, which have a high sulphur content, The bulk of the high sulphur coal is used in No. 3 boiler house. In 1927 grit catchers were installed in the stacks of this house, Jat a cast of $125,000, to eliminate grit Jand cinders. At the time of installation sulphur was not a problem, Manchurian and Japanese coals were available, These grit catchers will of eliminate sulphur, and tests of these grit catchers made concur rently with tests of the grit washers of No, 4 house indicate that they are not very efficient in the elimination of cinders and grit,
