Description

This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1911 edition. Excerpt: ...lower part is practically a set of grate bars. Gases and vapors escape from the top. The cylinder is entirely inclosed by an iron mantle. Provision is made for the continuous ignition of airdried peat at the top of the generator. After the cylinder has been charged with peat, a mixture of air and steam, previously heated to over 400, is admitted to the enveloping chamber. The current enters through the perforations into the central section of the generator, and through the grate at the bottom. The hydrolysis of the nitrogen takes place in the middle zone of the generator, while carbonized peat descends to the lower portion to undergo a restricted combustion at a more elevated temperature. As a result, the expulsion of the water from the damp peat and its gasification take place simultaneously. Nearly 80 per cent of the nitrogen present is transformed into ammonia, and excellent power gas is secured. PRODUCTION AT THE MONT CENIS WORKS. The composition of the power gas as secured at the Mont Cenis works is 16 per cent CO., 16 per cent CO, 26 per cent IT, 5 per cent CH4. and 37 per cent N. When the percentage of nitrogen in dry peat is 1 (the ordinary figure) the yield of ammonium sulphate per ton of dry peat is 40 kilos. With 2 per cent of nitrogen it reaches 85 kilos and with 3 per cent 130 kilos. The gas has a thermal value of 1,250 to 1,350 calories. After deduction of what is needed for motive power, etc., the gas yielded by 1 ton of dry peat, in the damp form (containing 50 to GO per cent of water), is capable of generating 650 to 750 horsepower hours in gas motor engines. When production is continuous the figure rises to 900 horsepower hours. If the percentage of nitrogen reaches 1.25 per cent (calculated as before, to perfectly dry...show more
